How to read SKF 7317 BEGAF
- 73Series
- Angular contact ball bearings, 73 series. For the same bore, each series has a different outside diameter and width.
- 17Bore
- 85 mm bore: 17 × 5.
- BEGAFSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
7317 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF angular contact bearings of the BEGAF series are single-row bearings with a contact angle that allows them to support radial and axial loads in one direction. They are generally mounted in pairs and are used in applications requiring high precision and rigidity, such as machine tool spindles, pumps and gearboxes. At MR Accesorios Industriales we carry them as part of our SKF bearing line.
The designation of these bearings follows the SKF system: the basic number (for example, 7216, 7310) indicates the size and the dimension series. The 72 series corresponds to medium-section angular contact bearings, while the 73 series has a wider section and higher load capacity. The suffix B indicates a 40° contact angle, and EGAF refers to the internal design, machined brass cage and other construction features. Thus, a 7216 BEGAF is a 72 series angular contact bearing with a 40° angle and a brass cage.
These bearings are used in industries such as metalworking, petrochemical, food and power generation. Typical applications include machine tool main spindles, centrifugal pumps, compressors, gearboxes and gear cases. In Argentina, they are found in industrial plant equipment, machining workshops and production lines where combined loads must be supported with high precision and rigidity.
To select an angular contact bearing, take into account the magnitude and direction of the loads, the rotation speed and the environmental conditions. Mounting must ensure precise alignment; they are generally mounted in pairs, with preload or controlled axial clearance depending on the application. Proper lubrication (grease or oil) and effective sealing are key to extending service life. It is essential to follow the manufacturer's recommendations for mounting and axial fixing.
Regarding equivalents, SKF angular contact bearings can be interchanged with those of other brands that follow the same dimensional and contact angle designation, such as FAG, NSK or NTN, but always verify the tolerances and internal design. For replacements, it is important to compare not only the basic number but also the suffixes that indicate features such as the angle and the cage.

Frequently Asked Questions
- What are the dimensions of the SKF 7317 BEGAF bearing?
- The SKF 7317 BEGAF bearing has a 85 mm bore, a 180 mm outside diameter and a 41 mm width (85 x 180 x 41 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 7317.
- What does the BEGAF suffix mean on an SKF bearing?
- The BEGAF suffix indicates internal features: B corresponds to a 40° contact angle, E to the optimized design, G to the machined brass cage, A to an execution variant and F to additional features. Always verify the full designation to ensure interchangeability.
- Can they be mounted individually or do they require mounting in pairs?
- These bearings support axial load in one direction, so they are generally mounted in facing pairs to cover both directions. Individual mounting is possible if the axial load is in one direction and is compensated by another bearing.
- What lubrication do you recommend for these bearings?
- Lubrication depends on the operating speed and temperature. For high speeds, oil is recommended, while for moderate speeds a high-quality grease can be used. It is important to follow the manufacturer's specifications and maintain rigorous cleanliness.
