Strong, general use steel sheaved pulleys for applications with wire rope. 2- 3/8″ x 5/8″ single pulley featuring a steel sheave, stainless steel side plates and a sealed needle bearing. Bearings decrease the amount of surface area in contact with the axle, which creates a more efficient transfer. By rolling the load around the axle, load on the transfer point is increased, which results in faster wear, shortening the life of the pulley. Made in the U.S.A.
