Material Notes:
Ultraflon 601 (AC) POM lined metal backed bearing system, boundary lubrication required, high PV. Ultraflon 601 POM Liner is a lubricant enhanced acetal material for use in lubricated or unlubricated environments. With lubrication, PV ratings can be met without limitations. Lubrication reservoirs are available on the liner to produce a constant storage and pumping action for better hydrodynamic film generation.
