摘要

The linear unit (1) has a base element, at which a carriage (4) is mounted in a linear movable manner in axial direction of a main axis (3). The base element has multiple longitudinal guide paths (12,12a,12b) extended to the main axis. A supporting roller (22) is fixed with a carriage body (14) of a carriage. The supporting roller is movement-coupled with circumferential-sided circular-cylindrical bearing surface (23) such that supporting roller is unrolled during the linear movement of the carriage on the assigned guide paths.
