Overview

ZBR2203 FLG CARTRDGE BLK W/ND BRG
- Series 2000 collar mounted spherical roller bearing units provide economic and versatile arrangements for supporting shafts that carry substantial radial or combination radial and thrust loads and oscillatory or dynamic conditions
- The rollers are aligned by the retainers and the outer races, so despite misalignment, the roller load is always equally distributed across the surface
- This distribution of load, prevents high edge load stresses on the rollers and therefore it is not necessary to derate the bearing for misalignment conditions
- This series of bearing is easy to mount, sealed, prelubricated and does not require adjustment during mounting
- Cast iron housing
