Description: Cat® Machine Linkage Sleeve Bearings support rotational movement between machine frames, linkages and work tools. They are found mostly in the arms and buckets of machines. Genuine Cat Pin 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, surface finish, and manufacturing processes, to each part to enable them to work and wear effectively with all the other neighboring and dependent parts. Attributes: Cat heavy duty Sleeve Bearings are built with high grade steel and hardened for exceptional strength and wear life. They work as a system for your specific Cat machine and are tested and proven in the world's most severe applications. These bearings offer lower overall cost, outstanding strength and fatigue life, superior resistance to abrasive wear, and exceptional protection against galling, even in high-load conditions. Recommended Application: Cat Sleeve Bearings are designed for conditions that require demand and load strength for longer bearing life. Cat Sleeve Bearings are the top choice for maximum performance in demanding applications. They are designed to match to the mating pin.
