Description
Cat machine linkage pins support rotation between the frame, linkages and work tools. They are used anywhere rotation must occur between two structures. Genuine Cat pins and sleeve bearings are specially designed to work together as a system to deliver the performance you expect. Caterpillar design engineers match each part with the right combination of size, material, heat treatment, surface finish and manufacturing process so it works effectively and wears in sync with all other adjacent and dependent parts.

Applications
Cat hardened linkage pins are designed for situations that require superior load-carrying capacity, strength and wear resistance, extending pin joint life. Cat linkage pins are the first choice for maximizing performance in demanding applications.
