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
- Outside Diameter: 80 mm (3.1496 in)
- Inside Diameter: 70 mm (2.7559 in)
- Height: 40 mm (1.5748 in)
- Able to withstand high loads, with high hardness
- Supports high rotational speeds
- Smallest cross section among rolling bearings
- One-piece unit for easy handling and installation
Applications
Cat radial needle roller and cage groups are most commonly used in applications where the housing bore and shaft can serve as raceways. Typical applications for radial needle roller and cage groups are planetary gears, constant-mesh gears, idlers, and connecting rods.
