DX & DU (Dry Bushes And Washers), DX is a quality material which is used for applications of dry lubrication and is used in textile machineries, induction furnace, and so on. We use DX to manufacture top class dry bushes and washers. The DU (TFP) type bearing material is a PTFE and lead lining and is designed to operate without lubrication at temperatures between -200c and +280c. It can withstand specific loads up to 250Nmm, dependent on conditions.
