Decoding SKF 7308 BECAP
- 73Series
- Angular contact ball bearings, 73 series. Series differ in outside diameter and width even when the bore is the same.
- 08Bore
- Bore 40 mm (08 × 5).
- BECAPSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7308 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 7308 BECAP measures 40 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (40 x 90 x 23 mm).

Angular contact bearings from SKF handle combined radial and axial forces. The offset raceway design creates an oblique ball-to-raceway contact that gives high axial capacity in one direction, which suits arrangements that need stiffness and running accuracy.
The BECAP suffix breaks down into four parts: B for a 40° contact angle, EC for the optimized internal geometry with a polyamide cage and more balls, A for the standard execution variant, and P for normal precision tolerance. Reading the code this way, 7308 BECAP is a bearing from the 73 series built to BECAP characteristics, so you can identify the main features before opening a catalog.
Typical installations include machine tool spindles on milling machines and lathes, centrifugal pumps, screw compressors, speed reducers and transmission equipment, across metalworking, petrochemical, food and process plants. Because axial capacity runs in one direction only, these bearings usually work in pairs so the arrangement absorbs forces both ways.
Selection depends on load magnitude and direction, operating speed and the surrounding environment. Mounting calls for accurate alignment and, in many cases, a controlled preload. Grease or oil lubrication must match the duty, and sealing is chosen according to the contamination present. On paired arrangements, check axial clearance and confirm the layout.
SKF angular contact bearings can be interchanged with equivalents from other manufacturers that use the same international designation, provided dimensions and tolerances agree. Contact angle and internal design still need checking, since suffixes are not always equivalent between brands.

Frequently asked questions
- SKF 7308 BECAP bearing: what are its dimensions?
- SKF 7308 BECAP measures 40 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (40 x 90 x 23 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7308.
- What does the BECAP suffix mean on an SKF bearing?
- BECAP covers four points: B is a 40° contact angle, EC is the optimized internal design with polyamide cage and more balls, A is the standard execution variant, and P is normal precision tolerance. These define the main selection characteristics.
- How are angular contact bearings mounted?
- They are commonly mounted in pairs so the arrangement takes axial loads in both directions. Accurate alignment is important, and controlled preload is often required. Lubrication and sealing follow the working conditions.
- Can I replace an SKF bearing with another brand?
- Yes, when the international designation matches in dimensions and tolerances. Contact angle and internal design can differ between manufacturers, so validate the application before substituting.
