Cross-reference tables are useful when a maintenance team starts with a legacy marking rather than a drawing. The table below maps EP-KR / EP-KRV size references to IKO CF and WERB NAKD identification names. Treat it as an identification aid. A final replacement decision still needs the physical interface and ordered features checked.
| EVER POWER reference | IKO reference | WERB legacy reference | Outside diameter D* (mm) | Stud thread |
|---|---|---|---|---|
| EP-KR13 / EP-KRV13 | CF5 | NAKD13 | 13 | M5x0.8 |

Why a name match is not enough
Outer-ring profile, sealing, lubrication, tolerance details and eccentric or mounting features can differ between manufacturers or configurations even when a catalogue cross-reference points to the same nominal size. For an MRO replacement, send a clear photo of the marking and the mating-track arrangement, then measure the main dimensions where possible.
