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 Nonmetallic Self Lubricating Sleeve Bearings are produced from a special blend of woven fibers and resin for high strength and PTFE fibers for wear and galling resistance without grease or oil lubrication. 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 increase machine up time by eliminating the need to periodically lubricate the pin joints, but wear life may be less than that of a well lubricated hardened steel bearing.Applications:Cat Nonmetallic Self Lubricating Plain Sleeve Bearings are designed for conditions that require good load carrying capacity and superior galling resistance without periodic lubrication. Cat Sleeve Bearings are the top choice for maximum performance in demanding applications. They are designed to match to the mating pin.
