Shaft Materials, page 51 Wear and Pressure Different loads greatly infl uence the bearing wear. Among the iglidur plain bearings, certain materials are optimized for low loads, while others are better suited for high or extremely high loads. Wear and Temperature Within wide temperature ranges, the wear resistance of the iglidur® plain bearings shows little change. In the maximum temperature range, however, the temperature increases and the wear of the plain bearing increases. The table on the following page compares the “wear limits”. One particular exception is represented by iglidur® X. The wear resistance of iglidur® X increases greatly as temperature increases and reaches the optimum wear resistance at a temperature of + 160 °C. Then resistance decreases again, gradually.
