Single row needle roller bearings without inner ring consist of an outer ring assembly with needle rollers and cage. In applications with hardened and ground raceways on the shaft surface, this bearing is an excellent choice for compact bearing configurations. The outer ring contains two non-separable closed rings that act as retaining edges to guide the bearing axially.

• High radial load carrying capacity
• High rigidity
• Small cross-section
• Can withstand bi-directional axial displacement
