Patent ID: 8317397

Claim:
A linear ball bearing, comprising: a cage for receiving a plurality of axial ball loops which are distributed over a circumference of the cage, each of the ball loops having a first ball channel which is open radially to an inside and to an outside for a row of load-bearing balls, a second ball channel which is open radially to an outside for a row of non-load-bearing balls and deflection channels which connect the first ball channel and the second ball channel to one another, the cage having end edge sections and an outer circumferential face with predefined supporting regions and the supporting regions having positioning projections; at least one holding ring; and load-bearing carrying plates covering at least the first ball channel on the outside, the carrying plates having supporting faces with positioning recesses, which rest on the supporting regions on the outer circumferential face of the cage, wherein the carrying plates are positioned in a predefined position on the cage via positioning projections and the positioning recesses, wherein the carrying plates, which bear against the cage, are fixed on the cage by the at least one holding ring, which is pushed over the carrying plates, wherein one of the supporting faces, which rests on one of the supporting regions of the cage that lies between two of the ball loops, is formed on a longitudinal edge of a load-bearing face of the carrying plates that interacts with the load-bearing balls, and wherein the supporting faces, in axial end regions, are each widened in a circumferential direction to form an arcuate supporting foot, which rests on the end edge sections of the cage.
