How to read SKF 7220 BECBY
- 72Series
- Angular contact ball bearings, 72 series. For the same bore, each series has a different outside diameter and width.
- 20Bore
- 100 mm bore: 20 × 5.
- BECBYSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
7220 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 7220 BECBY bearing has a 100 mm bore, a 180 mm outside diameter and a 34 mm width (100 x 180 x 34 mm).

SKF BECBY series angular contact bearings are single row bearings with oblique raceways, designed to support combined radial and axial loads. They are used in applications where high precision and rigidity are required, such as machine tool spindles, pumps, compressors and gearboxes. Their angular contact design allows optimal load distribution, which translates into longer service life and reliability. At MR Accesorios Industriales we sell this SKF line, a brand we sell, to provide technical solutions in power transmission.
The designation of these bearings follows a clear scheme: the basic number, for example 7204, indicates the size and dimension series. The suffix B indicates a contact angle of 40°, while EC refers to a glass fiber reinforced polyamide cage, window, ball guided. The final Y indicates an optimized internal design. Thus, a 7206 BECBY is an angular contact bearing with those characteristics. Knowing these codes allows you to quickly identify the bearing's capabilities and its suitability for your application.
These bearings are used in industries such as metalworking, petrochemical, food and process industries. Typical applications include main spindles of milling machines and grinders, high-pressure centrifugal pumps, screw compressors, gearboxes and transmission equipment. In Argentina, they are common in the automotive sector, in machine tools and in pumping equipment. Their ability to support axial loads in one direction makes them ideal for paired arrangements, where two bearings are combined to absorb forces in both directions.
To correctly select an angular contact bearing, take into account the magnitude and direction of the loads, the rotation speed and the environmental conditions. Mounting requires precise alignment and adequate preload to achieve the necessary rigidity. Lubrication is critical: it can be grease or oil, depending on speed and temperature. Sealing will depend on external contamination; there are variants with seals or shields. Respect the specified internal clearance and avoid blows that could damage the raceways. Careful installation prolongs the service life of the bearing.
As for equivalences and interchangeability, SKF BECBY series angular contact bearings can be replaced by products from other brands that follow the same international designation. However, always verify the tolerances and contact angle, as they can vary between manufacturers. Interchangeability is not automatic: consult the technical specifications of each alternative. At MR Accesorios Industriales we can advise you on the best option for your equipment, guaranteeing compatibility and performance.

Frequently Asked Questions
- What are the dimensions of the SKF 7220 BECBY bearing?
- The SKF 7220 BECBY bearing has a 100 mm bore, a 180 mm outside diameter and a 34 mm width (100 x 180 x 34 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 7220.
- What does the BECBY suffix mean in an SKF bearing?
- The BECBY suffix indicates a contact angle of 40°, glass fiber reinforced polyamide cage, window, ball guided, and an optimized internal design. These codes define key characteristics for bearing selection.
- Can I replace a BECBY bearing with one from a different brand?
- Yes, as long as the international designation matches and tolerances and contact angle are verified. Not all manufacturers maintain the same specifications, so it is advisable to consult before interchanging.
- How should I mount an angular contact bearing?
- Mounting requires precise alignment and controlled preload. The manufacturer's instructions for internal clearance and lubrication must be followed. Avoid blows and make sure the support surfaces are clean and in good condition.
