The bolt shaft of the bolted roller bearing has been quenched in the rolling track area. The thick-walled outer ring of the roller features an arched outer surface to prevent concentration of applied force. The outer ring has two integral flanges, guided axially by the rollers. The bolt shaft head and the pressed side flange provide axial support to the outer ring through the rollers.

Outer race of bolted roller bearing (KR KRV series) contains a stop edge on the bolt and a fixed spacer on the bolt.
