Decoding SKF 7310 BEGAY
- 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).
- BEGAYSuffix
- 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 BEGAY measures 50 mm across the bore and 110 mm across the outside diameter; its width is 27 mm (50 x 110 x 27 mm).

For equipment that sees both radial and axial forces in one direction, SKF BEGAY series angular contact bearings are a common choice. Their angular raceway and ball arrangement allows higher speed and rigidity than deep groove ball bearings, which suits precision work in pumps, compressors, spindles and gearboxes. MR supplies this line to customers across the United States and Latin America.
Reading the designation helps you confirm the right part. Take 7310 BEGAY: the 73 prefix identifies a single row angular contact bearing with a particular raceway design. The 10 is the size code, which in the 73 series generally means a 50 mm bore. The BEGAY suffix carries the application detail: BE for a 40° contact angle, GA for reduced internal clearance, and Y for a machined brass cage.
These bearings appear in petrochemical, food, steel and power generation plants. Typical equipment includes centrifugal pumps, screw compressors, gearboxes, machine tool spindles and transmission units. Because they take axial load in one direction, they are often installed in pairs, face-to-face, so the pair handles forces in both directions. High-speed positions that need precision and rigidity are another common use.
Selection should start with load magnitude and direction, running speed and the environment. If contaminants are present, consider sealed or shielded variants. Internal clearance must match the application to avoid overheating or noise. Grease or oil lubrication is chosen based on speed and temperature. During mounting, alignment and fit are critical, since these bearings are sensitive to installation errors that shorten service life.
Several brands make angular contact bearings that can interchange when the main dimensions and load capacities match. Series and suffixes differ between manufacturers, so verify equivalences rather than relying on the part number alone. SKF offers a broad range with various contact angles and clearances. MR can advise on the best option for your equipment.

Frequently asked questions
- SKF 7310 BEGAY bearing: what are its dimensions?
- SKF 7310 BEGAY 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 BEGAY suffix mean in an SKF bearing?
- In the BEGAY suffix, BE indicates a 40° contact angle, GA indicates reduced internal clearance, and Y indicates a machined brass cage. These details define load capacity and speed behavior.
- How are angular contact bearings mounted?
- They are generally mounted in pairs, face-to-face or in tandem, to support axial loads in both directions. Precise alignment and correct fit are essential to avoid premature failure. Lubrication and sealing must suit the working conditions.
- Can I replace an SKF BEGAY bearing with another brand?
- Yes, as long as dimensions and load capacities are equivalent. Designations may vary between manufacturers, so verify the technical specifications. MR can help you find the right equivalent.
