What the designation 2200 ETN9 means
| Code | Meaning |
|---|---|
| 2 | Self-aligning ball bearing, wide width series (higher capacity) |
| 20 | bore code "20" = 20 × 5 = 10 mm |
| E | Optimized internal design |
| TN9 | Glass-fibre-reinforced PA66 cage |
Basic rating life of the 2200 ETN9
Basic rating life is L10 = (C / P)p million revolutions, where P is the equivalent dynamic load and p = 3 (ball bearing). For a 2200 ETN9 with C = 8.06 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 1.61 kN on this bearing. Use the Load Calculator to work out P for your actual radial and axial loads.
Equivalents of the 2200 ETN9
Brand-by-brand equivalents for this exact designation are not yet in the Rotec AI cross-reference tables. The Cross-Reference tool accepts SKF, FAG, NSK, NTN, Timken, Koyo and NRB designations, and shows what is catalogued.
Where the 2200 ETN9 is used
Self-aligning ball bearings are chosen for: Radial load with some axial load, where shaft/housing misalignment is expected. Typical equipment: Conveyors, agitators, textile machinery, general light-to-moderate industrial equipment. Self-aligning by design (spherical outer raceway) — most misalignment-tolerant ball bearing, but at lower load capacity for the same bore than a comparable deep groove ball.
Other sizes in the same series
The 2200 ETN9 is size 1 of 13 in the Rotec AI catalogue for the “2-series wide” series. The next size up, the 2201 ETN9, has a bore of 12 mm and a rating of 8.52 kN (+6%).
Common problems on bearings like the 2200 ETN9
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:
