RPMBRND — RPMBRND ZEF2303
- Provides economic and versatile arrangements for supporting shafts that carry substantial radial or combination radial and thrust loads and oscillatory or dynamic conditions
- 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
- Easy to mount, sealed, pre-lubricated and does not require adjustment during mounting
- Cast iron housing with contact seal
