Abstract

The stop (10) has a cage (26) including lower and upper annular elastic sealing lips (262, 264) radially arranged at the exterior of rolling bodies (24) e.g. balls, and whose contact walls are respectively supported against lower and upper washers (20, 22) or lower and upper supports (12, 16). The contact walls are formed of a solid polymer matrix including pores in which lubricant is confined. The lower support transmits forces of a coil spring to the lower washer and the upper support transmits the forces exerted by the upper washer to a body of a vehicle.
