Founded in 1990, China Famen Bearing Co., Ltd. is specialized torque coupling manufacturer and torque couplings distributor of all types of custom and cheap bearings. We obtained ISO9002, ISO14001, and QS9000 certificates in 1995 and 1996, 1999 respectively. Other advanced equipments include four RGB and RCI series heat treatment production lines with a treatment quantity totaling 1,500 kilograms per hour. The Multi-points temperature control meters and CNC display meters with bi-directional control have been adopted to complement these units.

Resists Shock and reverse backlash
Precise radial adjustment
Can be mounted directly over key way
Self Centering
Trantorque keyless bushings grip like a mechanical shrink fit on a shaft, eliminating backlash, and resisting shock and torque reversals better than keyways. Single-nut design self centers accurately and locks or unlocks with a twist of a wrench. Thus, hubless devices like plate sprockets, hubless gears and disc brakes can be easily mounted. Precise radial adjustment of timing gears permits exact initial timing with easy readjustment of the bushing being a major advantage over a fixed keyed connection. The Trantorque can be mounted directly over empty key ways to repair a worn or damaged connection. Bushings can be removed and reinstalled many times; a distinct advantage for prototype work and new product development. Replacement Torque Discs For Oldham couplers made from black Acetal. Conventional hub designs incorporate a tightening screw requiring the assembler to access the coupling through a hole in a flange in order to assemble it to a shaft. Often in a break-down maintenance situation the tightening screw does not line up with the flange access hole making nearly impossible to disassemble the coupling from the drive shaft. The BK5 is the perfect solution in this situation. The bellow also isolates the shaft bearings of the drive and driven elements from any side loading due to misalignment, thus extending their service life.

Type 303 Stainless
Low torque levels (0.01 oz. in.) with negligible power loss
Operating Angle: 5 degrees at full torque and RPM
Permits angular, radial and lateral misalignment
Exhibits low friction loss and has a low moment of inertia
This Stainless Steel Mini-Joint Coupling unit permits angular, radial and lateral misalignment in shaft location, without introducing loads or acceleration errors. The constant velocity assembly exhibits low friction loss and has a low moment of inertia, which allows the coupling to operate efficiently and smoothly, even at high speeds and can be used at low torque levels (0.01 oz. in.) with negligible power loss. Formed from Type 303 Stainless Steel and lubricated with molybdenum disulphide and grease. Used in many applications, from actuating of sensitive controls to couplings of rugged servo motors. Operating Angle: 5 degrees at full torque and RPM. Torque overload protection is often overlooked in machine design until something jams resulting in expensive damage and down time. The R+W Series SK5 safety coupling was developed specifically for this purpose. It uses a reliable ball detent system that is absolutely backlash-free and will disengage within 1 to 3 milliseconds when an overload is detected.
