SELECTION CONTEXT
Match the bearing
to its duty.
6307 belongs to the deep groove ball bearings family. Its reference envelope is 35 mm bore, 80 mm outside diameter and 21 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 35 × 80 × 21 mm establishes the boundary dimensions. The full designation, tolerances, clearance, contact angle or roller arrangement, seals, cage, lubrication and performance must also be checked.
