Description: Cat Machine Linkage Pins support rotational movement between machine frames, linkages, and work tools. They are found wherever rotation must occur between two structures. Genuine Cat Pins and Sleeve Bearings are specifically designed to operate as a system to deliver the performance you expect. Caterpillar design engineers match the right combination of dimensions, materials, heat treatment, surface treatments, and finish to each part to enable them to work and wear effectively with all the other neighboring and dependent parts. Attributes: Cat Linkage Pins are machined from high grade steel bar and hardened for exceptional strength and wear life. They work as part of the pin joint system for your specific Cat machine and are tested and proven in the world's most severe applications. The surface hardness, finish, and plating are selected for optimum performance with the sleeve bearing. They result in a lower overall cost, outstanding strength and fatigue life, superior resistance to abrasive wear, and exceptional protection against pin galling, even in high-load conditions.
