Plain bearings carry load by sliding. They are compact and lightweight and have a high load-carrying capacity. While most plain bearings require lubrication of some kind, polymer plain bearings can be made self-lubricating and dry-running. In this article, Matthew Aldridge describes some new developments in polymer bearing technology, which allow plain bearings to be used at a higher pressure and temperature than before.
