Kendrion UK Ltd (formerly Binder Magnete UK Ltd) is the U.K subsidiary of the Kendrion Group which specialise in products for a wide range of industries.

Binder offers a wide range of brake motors, from frame size 80 through to 180. Both brake and motor can have a protection degree of up to IP66. The motors are fitted with brakes which are all single disc, electrically released. Their ‘failsafe’ characteristic engages the brake.

Since the beginning of this century, Binder has utilised the power of magnetism for technical progress. Electromagnetic components have been produced for the automotive industry and power transmission markets.

Active Clutch Line

The ACTIVE CLUTCH LINE includes slip-ring free single-disc clutches for direct current in which the action of force of an electromagnetic field (electromagnetically closing) is used to transfer the torque. The ACTIVE CLUTCH LINE is characterized by a secure, residual moment-free lifting in any position and by a backlash-free transfer of the torque. During their whole life-time they require little or no maintenance. Depending on the clutch version a higher switching capacity can be achieved.

Classic Line

The CLASSIC LINE includes spring applied single-disc and multi-disc brakes for direct current which, due to their robust design and the variable connection technology, meet the requirements of demanding applications. Electromagnetically operated spring applied brakes build up the braking torque when the current is switched off and the electromagnetic force is therefore neutralized.

or over 50 years, Formsprag Freewheel Clutch has been the recognized leader in designing, manufacturing, and delivering dependable long-lived Overrunning Clutches to the power transmission markets.

By offering the broadest range of both Sprag and Ramp & Roller type overrunning clutches and backstops available in the world, Formsprag Clutch, together with its sister company Stieber Clutch in Germany, is the world's leading authority for solving applications requiring Overrunning Clutches.

Some of Formsprag's industrial products include:

Overrunning Clutches

All Formsprag/Stieber clutches described in this catalog are essentially “overrunning” clutches, i.e., they will drive in one direction but overrun (freewheel) in the other direction.Through the wide variety of designs offered by Formsprag Clutch and Stieber Clutch in both Sprag and Ramp & Roller Designs virtually any application can be met where this function is required.

Indexing Clutches

Through the wide variety of designs offered by Formsprag Clutch and Stieber Clutch in both Sprag and Ramp & Roller Designs, virtually any application can be met where reciprocating motion applied to the driving race is transformed into intermittent motion in only one direction at the driven race.

Bi-Directional Clutches

Available in six sizes, the Formsprag RL Clutch is a sprag type no-back which permits transmission of driving torque from input to output shaft in both directions of rotation, but restrains any feedback torque of the driven load from rotating the output shaft in either direction

Linear Bearings

Formsprag offers four different sizes of Rollerway linear bearings used for supporting and guiding heavy duty machine elements with low friction.

General Purpose – Ball Bearing Supported

The Freewheels are directional couplings, which means that the driving member rotates the driven member in one direction, while automatically disengaging itself from the driven part when the direction of rotation is reversed. The two operating states are Transmission of torque and Idling (Overrunning). two operating states are Transmission of torque and Idling (Overrunning).

Type CSK is a sprag type freewheel integrated into a 62 series ball bearing (except sizes 8 and 40). It is bearing supported, delivered grease lubricated and protected against dust of more than 0,3mm. The use of additional "nylos" type seals is recommended especially when the working temperature exceeds 50°C. Oil bath lubrication is also possible.

All the CSK versions are equipped with "Formchromed" sprags. The process increases several times the overrunning life time.

Torque transmission is ensured by a press fit assembly into a rigid outer housing with N6 tolerance, and onto a shaft with n6 tolerance. The initial bearing radial clearance is set at C5, and is reduced if using the press fit as specified.

CTS company, established in January 1977, started his activity with the aim of marketing bearings and special drives and, in the same year, started the production of cylindrical roller freewheels.

The GF Series (sizes 8.20) and GV Series are bushed; the GF Series (sizes 25.60) have ball bearings. The GF Series are used as intermittent feed, non-return and overspeed units mainly inside closed guards. To lubricate this range of freewheels, a pre-existing oil circulation may be sufficient, provided the type of oil used is one of those we recommend for cylindrical element contact units. The GV Series are used for return or intermittent feed applications and are located outside guards on drive shafts where the transmission torque is provided by the lever welded on the outer race. These types are supplied greased-for-life and with gasket.

US, USNU and UF Series freewheels used for intermittent feed, non-return or overspeed applications are generally placed inside closed guards (gears, end covers, etc.) in proximity to pre-existing bearings or additional bearings. The external and internal components must therefore be centred to each other; in the axial direction, they must not be under load or in tension. When pressing or extracting, simultaneously apply pressure both on the internal and external parts to avoid damage to the contact elements and springs. To lubricate this range of freewheels, a pre-existing oil circulation may be sufficient, provided the type of oil used is one of the recommended types for roller type

GM and GP are two types of cage, one with metric measures (GM) and the others with inches measures. The smaller dimensions and the high transmission torque offer some interesting technical and cost-saving solutions. When the application needs torques bigger it is possible to mount more cages side by side. The cage needs one or two bearings for centering, and the two rings (outer and inner) where the cage works must be a surface hardness of 60/62 HRC.

Cross and Morse Freewheels Clutch provide positive one-way drive with high torque capacity within a small unit. A ratchet and pawl mechanism is used with materials and heat treatment selected for a long operating life, with safe, positive transmission. IRF's are suited to low speed (up to 150 r.p.m.) overrun applications where shock loads may be encountered, such as Agricultural machinery. Standard stock units are available in two configurations; as standard sprocket for 1/2 inch pitch chains, or with a drilled flange to fit conveyor rollers, pulleys, or wheels. Standard units have threaded bore to cycle standards, but a range of Adapters enable fitting to keyed shafting. IRF clutches are also stocked in part-assembled condition for reworking to custom design, including finish parallel bore and key seat. Many special Industrial Ratchet Freewheels have been manufactured to meet customers' requirements with torques over 1,000.

Cross Safegard Overload Clutches
The Safegard series of overload clutches were developed to provide overload protection of high torque values with a compact unit. Directly interchangeable with other units in the market, this series offers low cost precision with minimal maintenance for a long reliable service life.
Safegard clutches are in two basic series, the Standard series, for optimum speed and torque, and the Mini series, for lower cost option on slower speed drives. Both series are also available as shaft couplings.

Torque Limiters & Couplings
The Morse Torque Limiter is a protective device that LIMITS TORQUE transmitted in a drive system by slipping when the torque demand exceed a preset value as a result of shock loads, overloads, or machine jams. It automatically re-engages when the overload torque has passed; no re-setting is required. It prevents machine damage and eliminates costly breakdown time.
The Torque Limiter utilises spring loaded friction surfaces for its operation; slip torque is preset by adjustment of the spring force. The Torque Limiter can be used with a sprocket, gear, sheave or flange as the centre member clamped between two friction facings. Offered complete with a range of specially machined platewheels and shaft to shaft couplings, with torque range 3 - 8540 Nm.


Spring loaded tensioners extend the life of roller chain, particularly on long centre distance drives. These products are suitable for simplex and multistrand applications.

Rotary Tensioner: Automatic 90° tensioning action.

Linear Tensioner: Automatic linear adjustment.

Straight Racks
Straight racks are available in standard lengths of 0.5, 1.0, 2.0 and 3 metres machined to 20° PA with pitch range 1 Mod. to 8 Mod. These are designed to combine with the standard spur gears to provide low cost conversion of rotary to linear motion.

The insert elements consist of a cage, sprags - number in relation to the shaft size - and a spring to preload the friction contact between the sprags and the mating parts. So called insert elements are not self centering and require additional bearing support for proper function as provided with our complete units, ball bearing sizes and backstops.

Function: The sprag clutch design shows at the contact surfaces a sophisticated geometrical shape, the engagement curve, which results in a certain pitch angle (αa, αi) when the sprags get in contact with the round mating parts. When torque is applied to the clutch the sprags roll in along the engagement curve until an equilibrium of forces between the torque and tension in the sprags and mating parts is achieved. This part of the engagement curve is called operating zon.

Fersa Bearings is a Spanish multinational company devoted to the design, development, manufacture and distribution of high-quality complete bearing solutions for the automotive market. We have over 50 years of industry expertise and –since 2016- we are part of Fersa Group together with the Austrian industrial bearing manufacturer, NKE.Tapered roller bearings This type of bearing is composed of an inner ring, outer ring, and tapered rolling elements. Thanks to the geometry of their design, tapered roller bearings can withstand combined loads (axial and radial). In addition, this design allows rolling movement without the rollers slipping off the tracks of the outer and inner rings.
Cylindrical roller bearingsThe cylindrical roller bearings are bearings capable of enduring high radial loads. This typology has high resistance to rapid and high accelerations thanks to the line contact between the rollers and the rolling tracks.Ball bearingsThe deep groove ball bearings are composed of an inner and an outer ring as well as a cage with a precision ball set.
These bearings are mainly designed to support radial and axial loads from any direction and allow operation at a relatively high speed.
Needle bearingsNeedle bearings are distinguished by being formed by a cage that houses a large number of rollers with a much smaller diameter in relation to its length. Needle bearings have a high load capacity taking into account the size of their section.
