LINEAR MOTION BALL BEARING

摘要

A ball bearing assembly for guiding two machine parts in linear relative motion. Upper (130), intermediate (150) and lower (170) members are assembled to an inverted U-shaped bearing body (120) which straddles the sides of a rail base (96). Grooves formed between the members and the bearing body provide circulation paths on either side of the rail base for ball bearings. All components are accommodated within the width of the bearing body.
