<p>A roller unit (RU) (200) has rollers (231, 241) to run on profiled elements (101, 102) on opposite sides of a rail (100). The rollers are mounted on the RU by means of pre-stressed angular ball-bearings (236, 246) and can be pre-stressed in relation to the rails by a pre-determined force. The RU and the rails can be displaced in relation to each other in the longitudinal direction of the rails. An independent claim is also included for a roller unit for a linear guide.</p> |
