Indusco replacement sheave with bronze bushed. Designed for small size wire rope and cable. Low carbon steel is used in the side plates while the sheaves are turned down using cold-rolled bar stock. The bearings are made from a combination of bronze and steel that is then oil impregnated to insure permanent self-lubrication. These bearings - specially designed for high load and medium speed applications - are then pressed into the sheaves. They are marked to comply with NIDA-SIDA standards.
