摘要

The roller has a free-wheeled bush bearing (4) installed between two ball bearings, and a front roller (1) rotating only in a direction of travel due to the bush bearing. A metal sleeve (3) is integrated in the front roller so that a fixed seat is made available for the bush bearing. A tappet (5) is provided with left-handed and right-handed threads in order to inhibit loosening of the front roller, during movement.
