Description:
Cat radial needle roller and cage assemblies are self-contained, ready to mount bearings designed to be used where the housing bore and shaft can act as raceways. They are 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.

Attributes:
• Type: RA-FWJ
• Housing Diameter: 86.023 mm (3.3867 in)
• Shaft Diameter: 65.989 mm (2.598 in)
• Height: 28 mm (1.102 in)
• High load carrying capacity and stiffness
• Supports high rotational speeds
• Lowest cross-section among rolling bearings
• Non-separable unit for ease of handling and installation

Application:
Cat radial needle roller and cage assemblies are most commonly used in applications where the housing bore and shaft can be used as raceways. Typical applications for radial needle roller and cage assemblies are planetary gears, constant-mesh gears, idler gears and connecting rods.
