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

• High radial load-bearing capacity
• High rigidity
• Small cross-section
• It can withstand bidirectional axial displacement
