Decoding SKF 7308 BEGBY
- 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).
- BEGBYSuffix
- 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 BEGBY measures 40 mm across the bore and 90 mm across the outside diameter; its width is 23 mm (40 x 90 x 23 mm).

SKF BEGBY series bearings are single-row angular contact bearings built to take radial and axial loads acting together in one direction. Machine tool spindles, pumps and gearboxes are typical homes for them, where precision and rigidity matter. MR Industrial Accessories supplies this line within its SKF bearing catalog.
Reading the BEGBY code helps you confirm what you are ordering. The digits at the front give the size and dimension series, as in 7211, 7306 or 7308. B stands for a 40° contact angle, so the bearing can carry significant axial load. E signals an internal design with improved load capacity. G points to a special cage treatment that lowers noise and vibration. Y means a one-piece inner ring with a polyamide cage. Together, these suffixes suit demanding duty.
You will find these bearings in metalworking, food, petrochemical and mining operations. They sit in milling machine and lathe spindles, centrifugal pumps, compressors, speed reducers and transmission equipment. Because they take combined loads, they fit assemblies where the shaft has to turn with precision and rigidity, such as machine tools and precision equipment.
Selection starts with load direction and size, rotation speed and the surrounding conditions. Mount the bearing with the contact angle facing the right way, and expect to set axial adjustment to reach the internal clearance you need. Pick lubrication that matches operating temperature and speed, check shaft-to-housing alignment to avoid extra stress, and choose sealing based on contamination; in dirty areas, sealed or shielded bearings are the better choice.
For interchangeability, SKF BEGBY series bearings can be replaced by bearings from other makers that use the same international designation, such as FAG, NSK or NTN, provided dimensions and contact angle match. Tolerances and internal clearance can differ from one manufacturer to another, so confirm them. When in doubt, give a specialist the complete bearing code.

Frequently asked questions
- SKF 7308 BEGBY bearing: what are its dimensions?
- SKF 7308 BEGBY 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 BEGBY suffix mean on an SKF bearing?
- BEGBY shows a 40° contact angle, improved load capacity, a polyamide cage and an internal design that cuts noise and vibration. It is an SKF designation for high-performance angular contact bearings.
- Where are BEGBY series angular contact bearings used?
- They serve applications needing combined load support and high precision, such as machine tool spindles, pumps, compressors, gearboxes and transmission equipment in metalworking, food and petrochemical industries.
- Are SKF BEGBY series bearings interchangeable with other brands?
- They can interchange with bearings from other brands that share the same international designation and dimensions. Check tolerances and internal clearance, since these vary between manufacturers, and consult a specialist.
