Choose the Series, Then Match the Machine Interface
The EP-KR / EP-KRV range is organized around the roller outside diameter and stud interface. The listed sizes run from 13 mm to 90 mm outside diameter. Product cards keep the familiar KR designation and the IKO CF reference beside the EVER POWER EP- model so engineers can compare a removed follower, a drawing and a replacement search in one place.
For replacement work, start with the dimensions you can measure: roller outside diameter D, roller width C, stud diameter, thread and mounting length. Then confirm whether the running surface needs the cylindrical KR execution, a spherical KRV execution, or an eccentric KRE/KRVE arrangement for adjustment.

The KR/KRV rating table provides C and C0 values but does not print their unit. Those values are shown without a unit rather than being labelled N or kN. Confirm the rating convention before using them in a bearing-life calculation.

View specificationsHow to Choose KR, KRV or an Eccentric Execution
KR — cylindrical running surface
Use the KR route when the machine drawing or removed follower calls for a cylindrical outer running surface and the mating cam or track is aligned to support the roller across its intended contact width.
KRV — spherical running surface
Use the KRV route when the ordered execution requires a spherical outer running surface. Confirm the actual profile on the removed part or drawing rather than assuming it from a shortened cross-reference code.
KRE / KRVE — eccentric adjustment
Eccentric versions are relevant only when the mechanism is designed to shift the follower position for clearance or track adjustment. The specification table lists an eccentric value e by size; mounting geometry still has to be checked.
| Selection point | What to verify | Why it matters |
|---|---|---|
| Roller size | D and C | Controls the track contact envelope and available space. |
| Stud interface | Stud diameter, thread and mounting length | Prevents a correct roller diameter from being paired with the wrong mounting interface. |
| Running surface | Cylindrical or spherical profile | The profile must suit the mating track and machine geometry. |
| Adjustment | Standard or eccentric execution | Eccentric adjustment is useful only when the mechanism provides an adjustment direction and locking method. |
| Designation | KR/KRV/CF/legacy code | Use the code to find a candidate row, then verify dimensions before ordering. |
Across the size table, the numeric KR/KRV size corresponds to the listed roller outside diameter D — for example KR30 is shown with D = 30 mm. Treat that as a quick identification aid, not a substitute for checking the full interface.
Full KR / KRV Cross-Reference Table
The table keeps EVER POWER, KR, KRV, IKO CF and legacy WERB references on the same row. Cross-reference codes are search and identification aids; verify dimensions, running-surface profile, sealing and any suffix-specific execution before replacement.
