The thermal expansion of polymers is approximately 10 to 20 times higher than metals. In contrast to metal, this expansion is non linear in plastics. The coeffi cient of thermal expansion of the iglidur® plain bearing is a signifi cant reason for the required play in the bearing. At the given application clearance, seizing of the bearing to the shaft does not occur at high temperatures. The coeffi cient of thermal expansion of iglidur® plain bearings was examined for signifi cant temperature ranges and the results are given in the individual materials tables, at the start of each chapter.
