SELECTION CONTEXT
Match the bearing
to its duty.
30212 belongs to the tapered roller bearings family. Its reference envelope is 60 mm bore, 110 mm outside diameter and 23.75 mm overall width or height.
Tapered rollers carry combined radial and axial load. Confirm cone and cup designations, overall width and arrangement before selecting a replacement.
For a manufacturing enquiry, provide the complete designation and operating conditions. Matching the dimensional envelope alone does not confirm interchangeability or equivalent performance.
Is the same size a direct replacement?
No. Matching 60 × 110 × 23.75 mm establishes the boundary dimensions. The full designation, tolerances, clearance, contact angle or roller arrangement, seals, cage, lubrication and performance must also be checked.
