Established in 1998, China Xiaowei Bearing Co., Ltd. is a high-tech enterprise specializing in torque coupling manufacturer and design many kinds of bearings. We have a modernized staffs of tech research and fog machine development, ISO9001 certificated, and manufacturing adopts advanced domestic and foreign standards such as GB, API, JIS, DIN, BS, NF and ANSI. Our custom torque couplings are exported to countries and regions in Europe(UK, France, Italy, Germany), North America(USA, Canda), the Middle East and Southeast Asia.

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.

This coupling also features a unique keyed tapered hub design allowing it to be quickly mounted and dismounted. When the two coupling halves are properly pretensioned this coupling is torsionally rigid with zero backlash. The stainless steel bellow compensates for axial, angular, and lateral misalignment simultaneously making this one of the most versitle couplings on the market.
