What the designation 7207 BEP means
| Code | Meaning |
|---|---|
| 72 | Angular contact ball bearing, light dimension series |
| 07 | bore code "07" = 7 × 5 = 35 mm |
| B | 40° contact angle |
| E | Optimized internal design |
| P | Glass-fibre-reinforced PA66 cage, ball-centred |
Basic rating life of the 7207 BEP
Basic rating life is L10 = (C / P)p million revolutions, where P is the equivalent dynamic load and p = 3 (ball bearing). For a 7207 BEP with C = 29.1 kN, the table shows what that gives at different load levels. It is the ISO 281 basic life only: it does not include lubrication, contamination, misalignment or reliability modifiers.
| C / P | P as share of C | L10 (million rev) | L10 at 1,500 rpm | L10 at 3,000 rpm |
|---|---|---|---|---|
| 3 | 33.3% | 27 | 300 | 150 |
| 5 | 20.0% | 125 | 1,400 | 690 |
| 8 | 12.5% | 512 | 5,700 | 2,800 |
| 12 | 8.3% | 1,728 | 19,200 | 9,600 |
For example, a C / P of 5 means the equivalent load is 5.82 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.
Equivalents of the 7207 BEP from other brands
These parts share the main boundary dimensions of the 7207 BEP and are commonly used as its equivalent. Published load ratings differ a little between makers because internal designs differ.
| Brand | Part | C (kN) | C0 (kN) | Dynamic rating vs SKF |
|---|---|---|---|---|
| SKF | 7207 BEP | 29.1 | 19 | Reference |
| Timken | 7207 B | 27.1 | 18.4 | 93% of SKF |
Check clearance class, cage, seals and any special suffix before ordering. A matching main size does not guarantee the parts are interchangeable in every detail.
Where the 7207 BEP is used
Angular-contact ball bearings are chosen for: Combined radial and axial load; precision/high-speed arrangements. Typical equipment: Pumps, compressors, spindles, generators, aerospace accessories. Often paired/preloaded; contact angle and lubrication matter.
Other sizes in the same series
The 7207 BEP belongs to the “72 light” series. The next size down, the 7206 BEP, has a bore of 30 mm and a dynamic rating of 22.5 kN. The next size up, the 7208 BEP, has a bore of 40 mm and a rating of 34.5 kN (+19%).
Common problems on bearings like the 7207 BEP
Most field failures trace back to lubrication, contamination, fits and alignment rather than the bearing itself. These guides explain how to recognise and prevent them:
