Standard round belts and V-belt idler pulleys are available. UHMWPE, which is impact resistant, makes superior line shaft pulleys.
We offer a wide variety of custom-designed UHMW pulleys that meet customer specifications. Our UHMW pulleys are self-lubricating and offer wear and noise reduction advantages over their metal counterparts. UHMW pulley features higher impact strength with more chemical resistance and display high abrasion resistance with near-zero water absorption.
