Angular Contact Ball Bearings

7313 at a glance

7313 identifies a angular contact ball bearing reference with 65 mm bore, 140 mm outside diameter and 33 mm overall width or height.

Bore / d: 65 mm
Outside / D: 140 mm
Width / B: 33 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.

7313 belongs to the angular contact ball bearings family. Its reference envelope is 65 mm bore, 140 mm outside diameter and 33 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 65 × 140 × 33 mm establishes the boundary dimensions. The full designation, tolerances, clearance, contact angle or roller arrangement, seals, cage, lubrication and performance must also be checked.
