Overview

INA K115X123X27 Needle Roller Cage Assembly is an ultra-light radial load element consisting only of needle rollers and a cage, without inner or outer rings. It uses adjacent components as raceways, making it ideal for gears, connecting rods, and compact drives needing high load capacity in minimum radial space.

The cage guides needle rollers at uniform spacing, while the shaft and housing bore act as raceways. Hardness, surface finish, and geometrical accuracy of these mating surfaces determine bearing performance.

Key features

High radial load capacity in minimum space
Lightweight design without inner or outer rings
Cage guidance supports high-speed operation
High design flexibility using mating 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.
