137-2919: 80.25mm Internal Diameter Sleeve Bearing

Description:Cat® Machine Linkage Sleeve Bearings support rotational movement between machine frames, linkages and work tools. They are found mostly in the arms, links, and cylinders of machines. 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, 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 machined from high grade steel and hardened with a special heat treat process for exceptional galling resistance, 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. 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.Applications:Cat Hardened Steel Plain Sleeve Bearings with Special Heat Treat are designed for conditions that require exceptional galling resistance and superior load carrying capacity, strength and wear resistance 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.
