UHMW Sprockets

 Mill chain sprockets are machined or molded from UHMW or polyurethane. With superior impact resistance and light weight, they reduce operating noise and are easy on the chain, prolonging life far beyond a metal-to-metal system. These sprockets resist chemicals and need no lubrication or bearings. All sizes and tooth profiles are available, as well as splits and drives. the charts below show some of the typical sprockets we supply. Call or email us for your special requirements.
