RNR 4 in Single Service Line Pulley w/Aluminum Sheave & Steel Sideplates

$89.50

Description

4″ x 1/2″ single pulley featuring an aluminum sheave, stainless steel side plates and a roller 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 USA.
