Overview

INA HK4518-RS Drawn Cup Needle Roller Bearing with open ends is a compact radial bearing with a thin-walled drawn outer ring and needle rollers. It is pressed into the housing bore, providing an economical high-load solution for gears, levers, and small drive units with limited radial space.

The thin outer ring is produced by forming and has open ends for through-shaft arrangements. It commonly runs directly on the shaft without an inner ring, so shaft surface quality and lubrication must be controlled.

Key features

Very low radial cross-section
Press-fit mounting with minimal axial retention parts
High radial load capacity
Cost-effective compact design

Typical applications

Small gearboxes
Levers, hinges, and pivots
Automotive auxiliary devices
Power tools and small motors

Selection guidance

Verify housing bore tolerance, shaft hardness and finish, lubrication method, sealing need, and through-shaft arrangement.
