INA BK0509-B Nadelhülse (geschlossen)

Overview

INA BK0509-B Drawn Cup Needle Roller Bearing with closed end uses a thin-walled outer ring closed on one side to support shaft ends while saving space. It suits compact gearboxes, levers, and automotive auxiliary devices requiring high radial load capacity at shaft-end positions.

One side of the formed thin outer ring is closed to cover the shaft end. Like open-end versions, it often runs directly on the shaft without an inner ring, making shaft surface quality and lubrication important.

Selection guidance

Check closed-end orientation, housing bore tolerance, shaft hardness, lubrication, and mounting depth.
