Overview

Needle roller and cage assembly

Needle roller and cage assemblies consist only of needle rollers and a cage, without inner or outer rings, using the shaft and housing directly as raceways. They are very compact and lightweight, accommodating high loads and speeds when used with hardened, ground shaft and housing surfaces.

Key features

Minimal section, no rings
Lightweight and compact
High radial load and speed
Shaft/housing serve as raceways

Typical applications

Gear bore supports
Connecting rods
Small reducers
Automotive and power tool drives

Selection guidance

Verify raceway hardness and finish of shaft and housing, lubrication, cage material, load, and speed.
