NK40/20 Budget Needle Roller Bearing 40mm x 50mm x 20mm
Single row needle roller bearing with machined rings, with flanges, without inner ring.
Single row needle roller bearings without an inner ring consist of an outer ring with a needle roller and cage assembly. They are an excellent choice for compact bearing arrangements in applications where hardened and ground raceways can be provided on the shaft. The outer ring includes two non-separable closure rings that act as flanges to guide the bearing axially.
