Linear rolling element bearing with rollers retained in a flexible cage

摘要

The device has a movable part (2) including a roller circulation passage with a loaded roller rolling surface (4d). The rollers are placed in the passage with a rotation axis of each roller parallel to each other to circulate based on a motion of the part (2) of a track part (1). Retainers hold the rollers slidable and rotatable. The part (1) has a protrusion in contact with an axis-line-direction end surface of the roller.
