PAGUFLEX® PLUS shaft couplings... the sure, uncomplicated, economical solution, if angled, radial and/or axially displaced drive shafts are to be frictionally connected.

Double loop-shaped, thermoplastic compensating coupling element made from HYTREL ®, a Thermoplastic Ether Ester Elastomer (TEEE) from DuPont.

Owing to the high reverse bending strength of the flexible material and the cardan-like shaping of the power transmitter, this development is the ingenious, technical solution for shaft displacement problems in motive power engineering, and in measurement and control techniques.

Recommendations for our products are for the design of: shaft-angle encoders, counting mechanisms, tachogenerators, servo valves, elevating tables, feeding drives, pumps, compressors and ventilators, kitchen equipment, office systems, textile machines and for numerous applications in the automobile and aircraft industries.

The one-piece coupling is frictionless, wear less, and silent, and works without any troubling effects (i.e., without troubling structure-borne sounds).

Thus, in changes of direction or rotation, or during torque fluctuations with load direction reversal, PAGUFLEX ® PLUS enables play-free and shock-free power transmission, together with effective vibration damping and sound insulation.

In numerous technical applications, the material HYTREL ® has been successfully substituted not only for established thermoplastics, but also for elastomers. It combines ideally the advantages of both materials, and is therefore the best innovation for flexible shaft couplings.

It enables the opening up of new areas of applications for extremely low and high temperatures. Also, in association with media in which, owing to their sensitivity, elastic elements have shown themselves to be of `limited use´. Further applications are those in which up to now the reverse bending strength of the material has set, narrow limits with regard to mechanical fatigue loading. In these, PAGUFLEX ® PLUS is now the solution.

The high flexibility of the thermoplastic coupling element effectively lightens the burden on the shaft bearings of motors and machines, even in circumstances of large radial and angular alignment errors. With the help of PAGUFLEX ® PLUS, the bearings run quieter, warm-up less, and achieve longer durability, thus lengthening service life.

RU-STEEL Italia S.R.L. is a medium company specialized in the field of the transmission couplings, from its first times (1958), the company is grown, step by step, increasing their capacities together in designing and manufacturing transmission couplings.

Since the first coupling produced, RU-STEEL’s philosophy has been designing and manufacturing a complete range of transmission couplings (from Nm 3 to 300.000, including “elastic couplings”, “self-lubricating coupling”, “flexible couplings”, “super elastic coupling”) in order to meet all customer’s requests.

TYPES OF RU-STEEL COUPLINGS

1) ELASTIC COUPLING - The RU-STEEL elastic coupling is composed with two equal gear rings, whose teeth engage themselves respectively with interposition of high resistance resilient blocks, which work only by compression. The use of RU-STEEL coupling assures the relief of incidental little misalignments between the connected shafts, which may depend, for instance, on unavoidable mistakes in the assembly, on thermic expansion, on elasticity of supporting structures, on ground settling, or on other causes. Furthermore the said coupling cushions the transmission of axial thrusts between the two connected shafts, because of its structural characteristics. G250 cast iron execution with 80Sh oil-resistant rubber plugs. It offers an elastic transmission by absorbing any shocks or vibrations, available in various lengths and sizes. It can work from -30 °C to + 120 °C.

2)   SELF-LUBRICATING GEAR COUPLINGS - The coupling of the “GD” set has got the main characteristic in the gears made by elements easily changeable in very strong resistance and self-lubricating material, while it intensifies the softness of the transmission, also avoids a further lubrication. The mentioned elements intersect each other into bores made half on the outer annulus gear and half on the inner hub. In that way the two edges, the inside of the annulus gear and the outside of the hub, can be compared to cogged surfaces and the driving elements, placed between the two constant-mesh gears, work as solid lubricating. Furthermore, the gear coupling of the “GD” set owns the capacity of working in both directions of rotation and with reversible of rotation and allows vertical and blind assembly. Execution in three pieces, completely metal in C 45 UNI EN ISO 10083/1/93, with cylinders in Teflon or bronze. These materials called "self-lubricating" allow axial sliding during the transmission of power. 

3)  FLOATING TEETH COUPLING (ZEUS) - RU-STEEL couplings with floating teeth type “ZEUS” are designed and manufactured to join two rotating shafts by transmitting a torque in a torsionally rigid way. They are totally manufactured in carbon steel “C 45”, they are composed by some hubs, produced with a “SPHERIC” toothing and by flanged coupling sleeves with a “CYLINDRICAL” toothing. The torque is transmitted by the mutual engagement of the toothing’s junction of the flanges through some gauged bolts. Full steel execution in C 45 UNI EN ISO 10083/1/93. High transmission torques with small dimensions. 

4) RIGID COUPLINGS - Execution in cast iron G250 UNI ISO 185. Useful for connecting particularly long shafts of the same diameter, both with and without key. Completely rigid transmission.

5) FLEXIBLE ALL STEEL COUPLINGS - Full steel execution in C 45 UNI EN ISO 10083/1/93, with reinforced lamellar packs in AISI 304 10083/1/97 stainless steel, flexible but torsionally rigid, without spacer, ATEX certified.

Founded in 1975, Stafford Manufacturing Corp. is built on commitment to quality products, superior customer service and employee development. Arthur Stafford started the company on a shoestring budget but with a clear vision of what was required to accomplish those goals.

Stafford Manufacturing Corp. is a manufacturer and distributor of shaft collars, rigid shaft couplings and specialty mechanical components.

They’re used in a wide range of industrial and consumer OEM and MRO applications, including:

Power transmission

Linear motion

Motion control

Fixturing

Material handling

Display

Automation

Assembly

Shaft collars are machine components featuring a simple design that consists of a round metal or plastic ring with a clamp screw or screws. Tightening the screws causes the ring to tighten or loosen around the shaft. When securely tightened, shaft collars can serve as mechanical stops or hold components in place along a shaft. Despite their simple design, shaft collars play an important role in a wide range of industrial applications. 

TYPES OF SHAFT COLLARS

Shaft collars provide three primary functions: 1) holding components in place, 2) locating or positioning components on a shaft, and 3) creating an attachment between shaft and another component. Some of the types commonly available include:

Threaded shaft collars. Threaded shaft collars have a threaded interior that allows for use on threaded shafts, making them an excellent choice for heavy-load applications requiring high axial holding power. The threaded design also allows for easy adjustments and precise positioning.

One-piece shaft collars. They feature a simple design featuring a single screw. They work by surrounding the shaft with an evenly distributed compressive force . Since they cannot be disassembled, one-piece collars are only suitable for applications where the end of the shaft is accessible.

Two-piece shaft collars. These can be completely disassembled, allowing them to be used in situations where the end of the shaft is not accessible. Two-piece collars also provide greater holding force and shock-load resistance.

Hinge shaft collars. Their design allows for easy disassembly and reassembly along the shaft. They consist of a single unit that can be installed without the risk of dropping loose parts.

Heavy-duty shaft collars. Compared to other shaft collar designs, heavy-duty shaft collars feature larger clamping screws and greater outer diameters and widths. The torsional holding capacity of heavy-duty collars is approximately twice that of standard collars.

Shaft Collar Bore Varieties. Bore shaft collars are manufactured in round, threaded, hexagonal, and square configurations. Round bore shaft collars are used as stops, locators, spacers, and bearing faces for a broad range of motion control, power transmission, and mounting applications. They are suitable for use on shafts, piping and tubing, and split hubs. Threaded bore shaft collars provide exceptional axial holding power without damaging threaded shafts. Their simple yet flexible design enables quick assembly and easy adjustments. Hexagonal shaft collars and square shaft collars are exclusively manufactured by Stafford Manufacturing to fit hexagonal or square shafts.

Product Details:

GZLINK is a modern enterprise focused on the design and manufacturing of high-precision shaft couplings and ball screw support unit. Established in 1998, the company has grown from a small producer into a major supplier of couplings with over 20 series of products, jaw type, disc type, bellows type, beam type, oldham type and so on.

 

The types of shaft couplings that we can provide are shown below:

1. Curved Jaw Coupling - The curved jaw coupling consists of two metal hubs and a polyurethane elastic body, which gives it an excellent impact absorption performance. 

2. Disc Coupling - The disc couplings consist of two metal hubs and a stainless membrane. The stainless membrane is thin and easy to bend, thus allowing it to better absorb deviations. The disc couplings are classified into a single and double membrane shaft coupling.

3. Beam Coupling - The beam couplings use the slit to balance the relative torque and transmit the torque. It features no backlash and is easy to maintain. Beam couplings are classified into helical slit couplings and parallel slit couplings.

4. Oldham Coupling - The Oldham couplings consist of two hubs and a centre block, with the centre block made of a plastic material in order to absorb deviation, reduce vibration, and ensure electrical insulation.

5. High-Gain Rubber Type Coupling - High-gain rubber type couplings consist of aluminium alloy and rubber. There is no clearance, and it features a better response ability over other shaft coupling types.

6. Bellows Coupling - The bellow couplings are capable of absorbing a large radical, axial and angular deviation.

7. Rigid Coupling - The rigid shaft couplings feature strict requirements for installation, and cannot deviate. Because of their small volume and easy installation, they are becoming increasingly popular.

8. Encoder Coupling - Encoder couplings are used in encoders, and are popular due to their excellent elasticity and ability to absorb a large deviation.

 

All are available in a variety of mounting options including set screw, keyway, clamp, conical and shrink disc configurations.

 

Uses of Shaft Coupling/Servo Motor Coupling:

• To transfer power from one end to another end.

(Commonly used in transferring motor power to another one).

• To provide for misalignment of the shafts

• To improve mechanical flexibility.

• To help/protect against overloads, reducing the transmission of shock loads from one shaft to another.

Magnaloy Coupling Company has been manufacturing precision machined products since 1956, including the original light weight, heavy-duty flexible drive coupling.  Today, Magnaloy offers many products in addition to Flexible Drive Couplings including, Pump/Motor Mounts, Cylinder Rod End Alignment Couplers, Hydraulic Manifolds & Manifolding Accessories and Hydraulic Reservoirs.

Flexible Drive Couplings
Magnaloy is the original lightweight, heavy-duty flexible drive coupling. Light weight magnesium construction makes Magnaloy couplings 76% lighter than cast iron and 36% lighter than aluminum units... and they’re stronger than either!

The benefits are many... Reduced loads on bearings, shafts and pumps, for longer component life. Easier handling and installation. Rust proof and corrosion resistant.

Magnaloy’s close machining tolerances (TIR of .002”) assures vibration-free operation and easy, accurate alignment without need for special tools. Solid magnesium alloy permanent mold castings are heat treated and offer the highest strength-toweight ratio available. They also offer better corrosion resistance and easier handling

Magnaloy Couplings are available with a variety of special features which include splined bores. Many additional splined bores are available by contacting the factory, including straight sided “PTO” type splines and metric splines.

The Clamp-Type Coupling utilized the basic Magnaloy coupling with the addition of the clamp feature. Developed to compensate for variations in spline formation methods and tolerances. Assures centering of the coupling and positive retention on the shaft. The clamp feature is suggested for all splined couplings, but is also available in smooth bored and keyed models.

Magnaloy’s Steel Bushed Splined Bore Coupling combines all the design and lightweight features of the Magnaloy Coupling with the added spline tooth strength and wear resistance of steel. Under normal conditions the standard “Splined Bore” coupling will perform satisfactorily and the addition of the “Clamp Feature” compensates for various fit conditions. When heavy cyclic loads, reverse loading and high torque loads exist in combination with fit variations, spline tooth failures and fretting can be corrected by utilizing Magnaloy’s steel bushed coupling. Of course, to achieve optimum benefits, Magnaloy’s clamp feature is recommended - assuring accurate centering and positive retention of the coupling on the shaft.

PM 90 Couplings
When your priorities for a coupling are economy and strength... specify the all-new Magnaloy Type PM90. The PM90 is made from high-density powdered metal and is available in standard bores up to 1 1/8 inch maximum. Double set screws are standard in all bores 1/2 inch and over. The set screws are placed over the keyway and at a 450 angle to the keyway to allow greater hoop-stress generation and maximum shaft gripping. Magnaloy’s exclusive insert design allows easy installation and replacement without hub removal. The drive lug design provides even compressive loading with no radial loading of insert drive elements.

Magnaloy Couplings offer four-way flexibility (parallel, angular, axial and torsional) and require no lubrication. They are easily installed and properly aligned without use of special tools or equipment - a straight edge and hex wrench are the only tools required. Magnaloy’s insert reduces noise and vibration and permits needed flexibility for proper operation within alignment capabilities.

Magnaloy Coupling’s full range of flexible inserts permit custom design performance for a wide range of applications. All insert materials offer complete electrical insulation, as Magnaloy’s design eliminates all metal-to-metal contact.

ECOLOC Couplings

 

ECOLOC Metal Bellows Couplings are characterized by proven quality at an attractive price. Backlash-free torque transmission and a very good balance of axial, radial and angular shaft misalignment are other features of these products. The shaft connection on both sides occurs by installation-friendly clamping hubs.

Series ECE ECOLOC

 

The Servo-Insert Couplings of the series ECOLOC ECE are used wherever vibration damping is required. By an optimization of the spider an increased shaft misalignment compensation is achieved. The power transmission happens through a positive-locking keyway connection.

Metal Bellows Couplings

 

Metal bellows couplings made by GERWAH are the perfect choice in many areas where torsionally rigid and backlash-free shaft connections are required. Our high-quality products can compensate angular, axial and radial misalignments and transmit the rotational angle with highest precision. Compact shape and low moments of inertia can be taken for granted in our self-aligning couplings.

Line Shafts

 

GERWAH backlash-free Line Shafts are the perfect choice when large centre distances have to be covered. The elements are available with metal bellows or elastomeric spiders. Torque and rotating movements are transmitted with highest angular accuracy while misalignments are compensated easily. Installation lengths of up to six metres are possibl

The Kop-Flex® products continue to innovate the industry with leading solutions such as the evolutionary High-Performance Disc 2.0 coupling, torque monitoring systems, and patented ground bearing technology. The strength of the brand lies in its ability to provide a wide range of critical applications; from high-speed, High-Performance couplings for the Oil and Gas Industry, to high torque gear spindles for Metals and Mining applications.KOP-FLEX introduced the FAST’S® Gear Coupling in 1918. These have allowed KOP-FLEX to maintain its technological leadership in the coupling industry. It has distinguished itself in engineered couplings for high speed or high-performance applications, as well as in mill couplings.

KD® Disc Couplings KD flexible shaft couplings provide reliable transmission of mechanical power. This can be applied where a low maintenance, non-lubricated coupling is required. KD Disc Couplings are specifically designed to accommodate general purpose drive system applications such as centrifugal pumps, compressors, generators, cooling towers, machine tools, printing and pulp and paper machines.KD Couplings transmit torque and provide for both angular and axial misalignment between shafts with a coupling comprised of shaft mounted hubs connected through flexible disc packs with spacer or sleeve assemblies. All KD Couplings use stainless steel discs as flexible members, providing high strength and good corrosion resistance.

Gear CouplingsKop-Flex® offers the widest range of gear couplings, with no limit in sizes. Available with multiple different seal features and lubrication capacities. Available with alloy and nitride gearing to increase strength and extend wear.

FAST'S® Gear Couplings
The FAST’S® design, with its lifetime all-metal end ring, provides up to 300% greater lubricant capacity. This means that longer periods between relubrication may be scheduled. It is the only coupling designed to use oil lubrication. The all-metal end ring, used exclusively in FAST’S® couplings, eliminates the need for any type of perishable lube seal (o-rings, lip seals, cork gaskets, etc.). The end ring not only provides the dam over which lubricant must flow to escape, but it additionally pilots the sleeve with respect to the hub during start-up and shut-down operations. It further eliminates partial tooth disengagement with resulting tooth overloads by providing sleeve teeth which are flush against the inside wall of the end ring. WALDRON® Gear CouplingsFULL ENGAGEMENT TEETHThe WALDRON® gear coupling has been designed with full length tooth engagement with the inherent result of longer life and improved performance. OPTIONAL PILOT RINGSThe standard WALDRON® coupling consists of two identical half couplings. Optional precision steel pilot rings are available when more accurate centering of the two sleeves is required. HIGH MISALIGNMENT SEALCompetitive gear couplings incorporate an O-ring seal. In order to conform with today’s high misalignment capacities, this O-ring must fit into a groove that is larger than the ring. WALDRON® couplings use a truly high misalignment seal that seals remarkably under misaligned conditions.WALDRON® POWERLIGNThis flangeless design transmits identical torques as the standard WALDRON® Coupling. Having a smaller outside diameter, however, it is more compact, lighter, and can run at greater speeds
Elastomeric Couplings Kop-Flex® Elastomeric couplings use a flexible element to compensate for high angular misalignment and dampen torsional vibrations. Many models also feature a no lubrication schedule and provide virtually maintenance-free operation.

Product Details:

It all began in 1949, when Minnesota inventor Sterling Stageberg designed a unique mechanical variable speed transmission drive. Stageberg's design varied the output speed from a constant input from zero to maximum. Initially, it was used on automotive windshield wipers and became an instant success. The product filled an important industry need at the time, which helped launch the company. It also provided the idea for the Zero-Max brand, a name carried on all of today's Zero-Max products sold throughout the world.

Flexible Shaft Couplings

Shaft misalignment can limit the performance of machines, cause excessive wear, and often lead to premature failure. Flexible shaft couplings can help prevent these issues by transmitting torque while also accommodating for parallel, axial, and angular misalignment between drive components. High performance flexible shaft couplings can also reduce vibration, dampen noise, and protect drive shaft components from overload.
