INA HK2516B 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.
Verify housing bore tolerance, shaft hardness and finish, lubrication method, sealing need, and through-shaft arrangement.
