ZEF2212 PART NUMBER
Four-Bolt Square Roller Bearing Unit - Spherical Roller, 2-3/4 in Bore , Non-Expansion Bearing (Fixed), Standard Duty, Cast Iron, Concentric Collar
QTY QUOTERPMBRND - RPMBRND ZEF2212
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
