Abstract: A flanged linear ball bearing is provided with a linearly translocatable flange which can be secured to a flange support. A gap is formed between the flange and the ball bearing proper and an intermediate member is adapted to fit in the gap so as to secure the flange to the outside of the bearing proper. The flange is adapted to be secured to a flange support which extends around the bearing proper.

Abstract: A linear ball bearing has a bearing proper in sliding engagement with a guide member through a plurality of balls. The bearing proper is made up of an intermediate member and a pair of end members each of which is provided on a respective end of the intermediate member. The intermediate member in turn is provided with at least one holding hole and a holding groove associated with each holding hole. The holding groove has a slit which is open to and extends along the surface of the intermediate member. Each of the end members has a transfer groove open between a respective holding hole and a respective holding groove. The holding hole, the holding groove and the transfer grooves collectively define a ball circulating passageway through which a plurality of balls are circulated.
