Sferax is a Swiss company that specialises in linear bearings manufacture. They produce a wide variety of different bearing types, including Metric ball bearings, Open ball bearings and Miniature ball bearings. Sferax also produces Compact ball bearings and bearings for rotating shafts in both stainless steel and other materials.
A Brief History of Sferax Linear Bearings Manufacture
The Sferax company was originally founded by Claude-André Bétrix back in 1962, before notable expansions in 1967 and 1980 brought the company closer to the globally renowned entity they are regarded as today. These days, not only do they continue to operate out of their main facility in Cortaillod in the west of Switzerland (in a building architecturally designed by Bétrix’s eldest daughter), but they also have subsidiary premises in Emmendingen, Germany.
Sferax Linear Bearing Product Specifications
The dynamic load of Sferax linear bearings is usually half of a static load, with the preload specifications depending on the application of the machinery they are being used with and the dimension they are intended to fit. In general, it can be anywhere between 0.002 and 0.02mm on the shaft diameter.
The maximum movement speed for the ‘Standard’ Sferax linear ball bearing is 5 m/s, with an acceleration of 100 m/s squared (150 m/s squared for the ‘Special’ Sferax linear ball bearings). It should also be noted that in the event of ball-bearing movement, there must be a reduction of the speed at the end of the stroke.
As the Sferax linear bearings feature a significant reduction in friction, this allows any heavy loads they are managing to be shifted longitudinally with a minimum expenditure of power and energy. This makes the Sferax linear ball bearings some of the most energy and power efficient bearings on the market, hence their popularity around the world.
The bearings do require lubrication, with there being a strong preference for thin-bodied oil during high speed applications. A lithium-based grease is recommended, but again the viscosity will be entirely dependent on how much speed is being applied in the process. If it is a slower paced application, then a thicker lube is fine, but the faster the process goes the thinner the lubricant needs to be to allow the bearings to operate at full functionality.
Sferax Linear Bearings Maintenance Advice
It’s imperative that the bearings are kept clean, so make use of rectified benzene and/or petroleum to ensure the cleanliness of the bearing is maintained. Another good piece of advice regarding keeping the bearings clean is to use compressed air, either in a canister or other source. This allows you to blast the hard to reach areas clean without causing them any unnecessary wear and tear.

The Rollon range consists of three product lines that provide effective solutions for a wide range of industries and application. These include aerospace, railway, medical, special vehicles, automation and industrial machinery.Linear Line
Rollon’s Linear line is a range of dedicated linear motion rails. The range includes roller guides and recirculating ball bearing carriages. Rails and sliders are available in various profiles, sizes and types to suit all applications.Telescopic Line
The Rollon Telescopic Rail product line is made up of eight models with full and partial extension, with various cross-sections and intermediate elements, in S-shape, double T or square. High loads, in combination with cost-efficiency and free movement, have long been the outstanding properties of the Telescopic Rail product line.Actuator Line
The Rollon Actuator line is dedicated to linear actuators and linear motion systems. Their linear units feature extruded aluminium profile, and are available in different types of belt and ball screw driven models and configurations.

Thread rolling is the core expertise of Eichenberger Gewinde AG. Not surprisingly, we utilize this process to form the thread profiles of all the screws we produce.
Even though all Eichenberger lead screws are made using the rational thread rolling process, individual model series feature distinct differences in design and performance. Product characteristics therefore need to be considered when selecting the right product.

MSA Series MSA series can achieve a well balanced preload for increasing rigidity in four directions while keeping a low frictional resistance. This is especially suit to high precision and high rigidity required motion.
MSB Series MSB series can achieve a well balanced preload for increasing rigidity in four directions while keeping a low frictional resistance. This is especially suit to high precision and high rigidity required motion.
MSR Series The full roller type linear guideway, MSR series, equip with rollers instead of the ball, and therefore the MSR series can provide higher rigidity and loading than the normal type with the same size. Especially suit for the requests of high accuracy, heavy load and high rigidity.
MSC Series MSC stows with Gothic-arch groove and designed to contact angle of 45° which enables it to bear an equal load in radial, reversed radial and lateral directions. Furthermore, ultra compact and low friction resistance design is suit to compact equipment. The lubrication route makes the lubricant evenly distribute in each circulation loop.
SME Series The ball chain type linear guideway, SME series, equip with the patent of ball chain design can make the vement smooth and stability, especially suit for the requests of high speed, high accuracy.
SMR Series The roller chain type linear guideway, SMR series, equip with rollers instead of the ball, and therefore the SMR series can provide higher rigidity and loading than the normal type with the same size. Besides, the patent of roller chain design can make the movement smooth and stability, especially suit for the requests of high accuracy, heavy load and high rigidity.

Bahr Modultechnik is a German manufacturer of Linear Positioning System made of aluminium profiles.The systems can have roll-guidings or linear ball guide ways.
These positioning systems can be driven by: ACME screw, ball, screw, tooth belt, rack or linear motor. Bahr offers these systems in following sizes: 30, 40, 60, 80, 80S, 100, 125, 60x120, 80x160 and 100x200.
For longer lengths, the system is delivered in more pieces with a jointing block. Bahr also has positioning systems for clean room applications.
A modern, pleasing and nevertheless timeless design, which easily inserts itself in each manufacturing route, distinguishes our positioning systems. Depending upon application, different guiding systems, propelled by toothed belts, ball screw spindles, trapezoidal screw spindles, racks or linear motors are available. Also the construction of wide portals over 12 meters length and 6 meter width is possible subject to our general term of delivery. By an innovative, future-oriented development the applications are unlimited to the users.
The EGT / EGK positioning system with spindle drive from Bahr Modultechnik is available in models with varied sizes like 30, 40, 60, and 80. This mechanical linear unit is engineered with external sliding guides with an inner trapezoidal thread. It is designed with the capability to provide operators with a trapezoidal thread speed that reaches up to 0.5 m/s.
DST/DSK positioning systems have a linear unit with two internal rail guides that support higher moments. An internal trapezoidal thread or a ball screw is used to drive the system. The positioning system DST P/DSK P has a rectangular aluminum profile and two rail guides. A rotating spindle with leading nut drives the carriage. If two linear units are made use of, or two carriages are mounted onto a unit, then the leading nut receiver can adjust the carriage symmetry. A curved aluminum sheet covers the carriage side. The carriage and the aluminum sheet have a small gap. The cover can be adjusted according to the mounting position.
