Abstract

A linear ball bearing with a substantially sleeve-like cage for receiving axial ball loops distributed across the circumference of the cage. Each ball loop has a first ball channel open radially to the inside and outside for the row of the carrying ball, and a second ball channel open radially towards the outside for the row of the non-carrying balls and has deflection channels connecting the ball channels of a ball loop to each other. At least the first ball channel is covered on the outside by a load-bearing carrier plate. Individual support surfaces on the carrier plates rest on predetermined support regions on the outer lateral surface of the cage. The carrier plates are positioned via interacting positioning projections in the predetermined positions on the cage. The carrier plates, which rest against the cage, are fixed to the cage via holding rings that are slid over the carrier plates.
