Decoding SKF 7310 BEGAF
- 73Series
- Angular contact ball bearings, 73 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- BEGAFSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7310 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 7310 BEGAF measures 50 mm across the bore and 110 mm across the outside diameter; its width is 27 mm (50 x 110 x 27 mm).

Single-row angular contact bearings in the SKF BEGAF range are built to carry radial and axial loads acting in one direction. Because of that one-direction capability, they normally work in pairs. Machine tool spindles, pumps and gearboxes are common homes for them, since those applications call for precision and rigidity. MR Industrial Accessories supplies this series within its SKF bearing offering.
Reading the SKF designation helps you order correctly. The basic number, such as 7216 or 7310, sets the size and the dimension series. A 72 number belongs to the medium section; a 73 number has a wider section and takes higher loads. The letter B means a 40° contact angle. The EGAF string covers the internal design, the machined brass cage and other construction details. So 7216 BEGAF is a 72 series bearing with a 40° angle and a brass cage.
Metalworking, petrochemical, food processing and power generation plants all use these bearings. You will find them in machine tool main spindles, centrifugal pumps, compressors, gearboxes and gear cases, wherever combined loads must be carried with precision and rigidity.
Choosing the right one starts with load size and direction, then running speed and the surrounding environment. Alignment at mounting has to be accurate. Pairs are the usual arrangement, set with preload or a controlled axial clearance depending on the job. Grease or oil lubrication, matched to the application, plus effective sealing, keeps service life where it should be. Follow the manufacturer's instructions for mounting and axial fixing.
For equivalents, bearings built to the same dimensions and contact angle designation can be swapped in, including products from FAG, NSK or NTN, but check tolerances and internal design first. When replacing, look beyond the basic number and compare the suffixes that define angle and cage. Ask us if you want help matching an equivalent.

Frequently asked questions
- SKF 7310 BEGAF bearing: what are its dimensions?
- SKF 7310 BEGAF measures 50 mm across the bore and 110 mm across the outside diameter; its width is 27 mm (50 x 110 x 27 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7310.
- What does the BEGAF suffix mean on an SKF bearing?
- BEGAF describes internal characteristics: B for the 40° contact angle, E for the optimized design, G for the machined brass cage, A for an execution variant and F for additional features. Check the full designation before confirming interchangeability.
- Can they be mounted individually or do they require mounting in pairs?
- Axial load is accepted in one direction only, so facing pairs are the usual setup to handle both directions. A single bearing can work if the axial load runs one way and another bearing counteracts it.
- What lubrication do you recommend for these bearings?
- It comes down to operating speed and temperature. Oil suits high speeds; a quality grease works at moderate speeds. Keep to the manufacturer's specifications and maintain strict cleanliness.
