Linear motion guide assembly consists of rail, block, balls, retainer, recirculator(reverse unit), sealing gasket and side panel. When the block moves in a linear direction relative to the rail, balls run along four raceway grooves which have been quenched and precisely finished. In the top of the block, balls again pass through the recirculator(reverse unit) into reciprocating hole then into raceway repeatedly. The recirculator(reverse unit) has rubber-sealing gasket on both sides to eliminate dust and keep foreign material away.

Advantage
By placing appropriate recirculating balls between rail and block, friction between the block and the rail changes from slide friction to rolling friction, the latter is less than the former greatly.
Then:
A. The difference between dynamic and static friction is small. It benefits to raise responsible speed and sensibility of CNC system. B. Required driving power could be slowed down greatly, compared to the traditional form, which is only 1/10. C. Compare to V type X-Y cross guide, resistance of friction is only 1/40 of the traditional form. D. Suitable for high-speed linear motion and instantaneous speed is 10 times of that of sliding guide. E. High positioning accuracy and high repetitive positioning accuracy.
Capacity of zero clearance motion, raising rigidity of the mechanical system.
Use double guides assembly, error homogenization effect can be attained, processing accuracy requirements can be lowered and cost of manufacture can be saved.
Suitable ratio of radius groove of raceway sectional plane assured that contact force turns small and carrying capacity and rigidity could be also raised greatly. Value of rolling friction is less than that of double-arc raceway.
Surface hardness process make guide good-adjustable; Core part keep good mechanical characters
