BK4520 SKF Drawn Cup Needle Roller Bearing With A Closed End 45x52x20mm

Drawn cup needle roller bearings, as the name suggests, are needle roller bearings with a deep drawn, thin walled outer ring with either open ends or a closed end. They are characterized by a very low sectional height and high load carrying capacity. Drawn cup needle roller bearings are typically used in applications where the housing bore cannot be used as a raceway for a needle roller and cage assembly, but where a very compact and economical bearing arrangement is required.

Generally, drawn cup needle roller bearings have a recommended maximum operating temperature of 140 °C, unless otherwise stated. The maximum operating temperature is limited by the seal and cage materials and the applied grease.
