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. The diameter of the holding holes and the holding grooves is slightly larger than the diameter of the balls to allow the balls to circulate therethrough while the width of the slit is narrower than the diameter of the balls such that the balls are retained in the holding grooves within the bearing proper while protruding from the bearing proper through the slits to contact and slidingly engage with the guide member.
