CuSn6P CuSn8P0.3 Bronze Thrust Washer with Lubricant Pockets
ZR-090W bronze thrust washer is made from high grade alloyed, hot rolled, phosphorous tin bronze . The slide bronze thrust washers are especially designed to withstand heavy loads and to be shock-resistant. The entire bearing sliding surface consists of lubrication pockets that build up a lubricating film that reduces friction, both at startup and during operation.
ZR-090W is intended for radial, oscillating and axial movements and are especially suited for medium to high loads.
Material Structure
