Angular Contact Ball Bearings
7318 at a glance
7318 identifies a angular contact ball bearing reference with 90 mm bore, 190 mm outside diameter and 43 mm overall width or height.
- Bore / d
- 90 mm
- Outside / D
- 190 mm
- Width / B
- 43 mm
A contact angle supports combined radial and axial loads. A single row supports axial load in one direction; paired arrangements require preload and matching to be specified.

SELECTION CONTEXT
Match the bearing
to its duty.
7318 belongs to the angular contact ball bearings family. Its reference envelope is 90 mm bore, 190 mm outside diameter and 43 mm overall width or height.
A contact angle supports combined radial and axial loads. A single row supports axial load in one direction; paired arrangements require preload and matching to be specified.
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 90 × 190 × 43 mm establishes the boundary dimensions. The full designation, tolerances, clearance, contact angle or roller arrangement, seals, cage, lubrication and performance must also be checked.
