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.Application:Consult your owner's manual or contact your local Cat Dealer for more information.
