1J-3710: Drawn Cup Needle Roller Bearing

Description: Cat drawn cup needle roller bearings such as 1J-3710 are self-contained, ready to mount bearings designed with a case-hardened cup which retains a full complement of through hardened needle rollers. This bearing is designed to carry large loads and function smoothly and dependably through high rotational speeds. 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.
