SELECTION CONTEXT
Match the bearing
to its duty.
6301 belongs to the deep groove ball bearings family. Its reference envelope is 12 mm bore, 37 mm outside diameter and 12 mm overall width or height.
Suitable for radial loads and moderate axial loads in both directions. Confirm sealing, clearance and lubrication for the duty.
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 12 × 37 × 12 mm establishes the boundary dimensions. The full designation, tolerances, clearance, contact angle or roller arrangement, seals, cage, lubrication and performance must also be checked.
