BK3020 INA Drawn Cup Needle Roller Bearing 30x37x20

BK3020 INA Drawn Cup Needle Roller Bearing 30x37x20 BK Series - Closed one end

Drawn Cup Needle Roller Bearings have a deep thin-walled outer ring with either open ends (HK series) or one closed end (BK series). They are designed for applications where the housing bore cannot be used as a raceway for a needle roller and cage assembly. Drawn cup needle roller bearings generally run directly on a shaft, if the shaft cannot be hardened and ground they can be combined with an inner ring.

Sealed bearings are available in this range and use the following suffix:

• RS - Seal on one side of the bearing
• 2RS - Sealed on both ends
