346-5215 Needle Bearing (Debris Resistant)
Cat® Cage and Roller Assembly Bearing
Description
Cat radial needle roller and cage assemblies are self-contained, ready-to-install bearings suited to applications where the housing bore and shaft serve as the raceways. They support heavy loads and run smoothly and reliably at high speeds.
Features
- Housing Diameter: 56.019 mm (2.205 in)
- Shaft Diameter: 39.99 mm (1.57 in)
- Height: 20.8 mm (0.818 in)
- High load capacity and rigidity
- Supports high rotational speeds
- Smallest cross section among rolling bearings
- Non-separable unit, easy to handle and install
Applications
Cat radial needle roller and cage assemblies are most commonly used in applications where the housing bore and shaft serve as the raceways. Typical applications for radial needle roller and cage assemblies are planetary gears, constant mesh gears, idler gears, and connecting rods.
