We are all aware that plastics expand and contract at different rates. When designing plastic plane bearings, one of the most critical considerations is to understand the thermal reactions of the material; designing not just for the normal operating temperatures of your environment, but to consider the minimum and maximum operating temperatures as well. Otherwise, you may lose the press fit (in cold temperatures) or expand to the point of shaft seizure (with hot temperatures).
