This is a drawn cup needle roller bearing. It uses a precision-formed steel cup as the outer raceway. The compact cup saves space and reduces weight. It fits applications with limited radial room.
It holds a full set of small-diameter needle rollers. These rollers have a high length-to-diameter ratio. They deliver strong radial load capacity in a small size. They also provide low friction and long wear life.
The bearing works in many applications. These include automotive transmissions, engines, and industrial pumps. It handles both rotating and oscillating motion. It needs only a hardened shaft as the inner raceway. This design cuts assembly size and cost.
