This thrust washer has excellent mechanical strength and is specialized for sliding performance. It can be used with no greaseless, and can be used on sliding parts to reduce the occurrence of friction and ensure a quiet. Excellent abrasion resistance properties such as back-and-forth moving parts and high-speed rotational parts. There are 1 cut out so you can install it in the middle of a shaft. UHPE is a sliding film with excellent abrasion resistance and low friction. Compared to conventional ultra-high molecular weight polyethylene, it can be used with a wide range of usage temperatures (heat resistance up to 30 degrees Celsius). Excellent mechanical strength and is ideal for applications such as thrust washers without lubrication. RoHS 2 compliant product.
