A linear rolling bearing comprises a guide carriage (1) that can be mounted on a guide rail (2) through rolling elements (5). The guide carriage (1) comprises at least one endless rolling element channel (3) for the rolling elements (5). The rolling element channel (3) comprises a load-bearing channel (4) for load-bearing rolling elements (5), a return channel (6) for returning rolling elements (5) and deflecting channels (7) arranged at both ends of the load-bearing channel (4) and the return channel (6), which deflecting channels (7) connect the load-bearing channel (4) and the return channel (6) endlessly to each other and deflect the rolling elements (5) out of the return channel (6) into the load-bearing channel (4), and vice versa. The rolling elements (5) are received in pockets (8) of a cage strip (9) having at least two free ends (13, 14). The cage strip (9) comprises spacers (10) that define the cage pockets (8) and are arranged, as seen in circulating direction, between successive rolling elements (5). The cage strip (9) further comprises cage belts (11) arranged on both sides of the rolling element row to connect the spacers (10) to one another. The cage belts (11) are received in guide channels (12) of the rolling element channel (3) for guiding the cage strip (9) in the rolling element channel (3). Adjacent free ends (13, 14) of the cage strip (9) comprise movable legs (15, 16, 22, 23, 27, 31) that are arranged substantially crosswise to the cage strip (9), and opposing end surfaces of the legs (15, 16, 22, 23, 27, 31) are configured as contact surfaces (17, 18, 24, 25, 28) for the legs (15, 16, 22, 23, 27, 31) with each other.
A linear rolling bearing comprising a guide carriage that can be mounted on a guide rail through rolling elements, said guide carriage comprising at least one endless rolling element channel for the rolling elements, said rolling element channel comprising a load-bearing channel for load-bearing rolling elements, a return channel for returning elements and deflecting channels arranged at two ends of the load-bearing channel and the return channel, which deflecting channels connect the load-bearing channel and the return channel endlessly to each other and deflect the rolling elements out of the return channel into the load-bearing channel, and vice versa, the rolling elements being received in pockets of a cage strip comprising at least two free ends, said cage strip further comprising spacers that define the pockets and are arranged, as seen in circulating direction, between successive rolling elements, said cage strip further comprising cage belts arranged on both sides of the rolling element row to connect the spacers to one another, the cage belts being received in guide channels of the rolling element channel for guiding the cage strip in the rolling element channel, wherein the free ends of the cage strip are adjacent to each other, and each of these adjacent free ends comprises a movable leg that is arranged substantially crosswise to the cage strip, and opposing end surfaces of the legs are configured as contact surfaces for the legs with each other.
