Decoding SKF 7221 BECBP
- 72Series
- Angular contact ball bearings, 72 series. Series differ in outside diameter and width even when the bore is the same.
- 21Bore
- Bore 105 mm (21 × 5).
- BECBPSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
7221 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 7221 BECBP measures 105 mm across the bore and 190 mm across the outside diameter; its width is 36 mm (105 x 190 x 36 mm).

The SKF 72 BECBP series covers single row angular contact ball bearings built to handle combined radial and axial loads in one direction. Their contact angle design suits setups that call for precision and rigidity.
The suffix tells you what you are holding. B is the 40° contact angle. E is a glass fibre reinforced polyamide cage. C is standard internal clearance for the series. The second B is a recess on the inner ring that simplifies mounting. P is normal tolerance. Bore sizes run across the series: the 7201 BECBP takes a 12 mm shaft, while the 7208 BECBP takes a 40 mm shaft. Reading the code this way speeds up identification on the floor.
These bearings fit equipment where radial and axial forces arrive together and precision matters: centrifugal pumps, compressors, machine tool spindles, gearboxes and transmission units. Because each bearing accepts axial load in only one direction, they are often mounted in opposed pairs so the arrangement covers both directions.
Selection comes down to the radial and axial load, the rotational speed, the internal clearance and the lubrication method. During mounting, alignment must be accurate and preload is often adjusted to achieve the required rigidity. The bearings are open; sealing depends on the working environment and can be handled with shield plates where needed. Grease or oil lubrication both apply. Keep the installation clean, since contamination shortens service life.
Interchange with other brands that use the same international designation is possible when dimensions and suffixes line up, but tolerances and internal clearance can differ between manufacturers, so confirm before substituting. For a replacement, send the complete part number from the original bearing or drawing.

Frequently asked questions
- SKF 7221 BECBP bearing: what are its dimensions?
- SKF 7221 BECBP measures 105 mm across the bore and 190 mm across the outside diameter; its width is 36 mm (105 x 190 x 36 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 7221.
- What does the BECBP suffix mean on an SKF bearing?
- B is the 40° contact angle. E is a glass fibre reinforced polyamide cage. C is standard internal clearance for the series. The second B is a recess in the inner ring for easier mounting. P is normal tolerance.
- Do these bearings come with seals or shields?
- No, the BECBP designation covers open bearings. Sealed versions exist in the series under other suffixes, so ask us if your application needs sealing.
- How do I know if I can replace a bearing from another brand with this SKF one?
- Check that bore, outside diameter and width match, and that the design type is the same. International designations are usually equivalent, but tolerances and internal clearance can vary, so confirm with our team before replacing.
