Founded in 1990, China Famen Bearing Co., Ltd. is specialized linear bearing manufacturer and linear bearings 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.

LSMs have better performance and higher power density than their induction counterparts, and they can operate with a larger mechanical clearance between their stationary and moving parts. Paying equal attention to the design and the applications of LSMs, Linear Synchronous Motors offers a unique opportunity to master the inner workings of LSMs, discover new research results, and keep abreast of their emerging applications. Electromechanical designers, electrical and mechanical engineers, as well as linear motor enthusiasts will welcome this broad and authoritative work to their reference collections. Four to six lines of balls arranged within a narrow space, supported by a tough outer shells, smoothly move against external forces applied from various directions forming an energy-efficient bearing with less sleeve resistance.

HEPHAIST SEIKO manufactures compact, easy-to-use and high performance linear ball bearings by rationally arranging solid plastic-structured cage, steel balls and snap rings on the outer shells of rational design structure based on the unique idea.
We first started the mass production of miniature series of linear ball bearings in the world. Compact, easy-to-use and high quality linear ball bearings of HEPHAIST SEIKO are important mechanical elements essential to mechatronics systems for speeding up, downsizing and energy saving.
Integrated flange type with cold forging has been developed. Different from the jointed flange type, it ensures high rigidity, machining accuracy and reliability. It also contributes to impact resistance and vibration resistance in actual use.
