Abstract
A plastic element with an outer surface defining a running surface, particularly for a belt or chain, arranged at the outer circumference of a metallic insert designed as a rolling or sliding bearing, consisting of a polymeric plastic material hardened after polymerization produced in a mold comprising adding an expanding agent to the polymeric plastic material by mixing, inserting the metallic insert into the mold, filling the mold with polymeric plastic material containing an expanding agent at a low pressure compared to injection molding pressures, allowing the polymeric plastic material to expand by action of the expanding agent to the outer surface of the metallic insert and to the mold to form the running surface and hardening the polymer plastic material.
