Description
EP-KR35 / EP-KRV35 is the EVER POWER designation for the 35 mm nominal outside-diameter size in the KR/KRV stud type track roller family. It uses a M16x1.5 stud, an outer-ring width of 18 mm and a speed reference of 10,000 rpm. This size is a practical screening point for industrial automation, packaging cams and machine subassemblies.

Dimensions and mounting interface
The move to M16×1.5 changes both the stud interface and overall length envelope. For retrofits, check wrench access, mounting-wall thickness and the relationship between the outer ring and cam track.
| Dimension | Value |
|---|---|
| G1 | 17 mm |
| B max | 19.6 mm |
| B1 max | 52.1 mm |
| B2 | 32.5 mm |
| B3 | 8 mm |
| C1 | 0.8 mm |
| rs min | 0.6 mm |
The move to M16 makes support thickness and tightening access more significant. Verify that the threaded member has enough engagement and that the shoulder seats squarely without the hex or tool fouling surrounding hardware.
Construction and configuration choices
The family can use a cylindrical or spherical outer surface depending on design. Confirm the mating-track geometry and edge-contact requirement.
When eccentric adjustment is required, use the KRE / KRVE naming as the enquiry reference and confirm the eccentric value and mounting orientation.
If the mechanism needs a particular KRV sealing arrangement, grease specification, clean-production lubricant or washdown resistance, state it as an ordered requirement.
Use the M16 follower where the cam reaction is carried radially through a stiff support. Visible side wear on the ring is a cue to inspect machine guidance and alignment before replacing the part.
The larger M16 mounting step makes support stiffness more visible. If the old follower loosened repeatedly, inspect the mounting face and thread condition before assuming the bearing itself was the root cause.
Size-specific selection perspective
Where EP-KR35 / EP-KRV35 fits
At 35 mm outside diameter the series changes to an M16×1.5 stud, which shifts the selection emphasis toward support stiffness and mounting-wall geometry. This size can suit industrial automation and packaging subassemblies that need a more substantial follower without moving into the M18/M20 groups. Retrofit work should include a check of the threaded engagement, shoulder seating and tool access around the larger hex/stud area. If the old follower shows edge polishing or asymmetric wear, inspect the track alignment before fitting a replacement. For a new mechanism, consider how the support deforms under the real radial contact path; a nominal bearing size cannot compensate for a flexible or poorly aligned mounting structure.
Begin with the M16 support interface and the thicker mounting member it usually implies. Next check track alignment, radial contact width and service access; these factors distinguish a workable EP-KR35 installation from a thread-only match.
Replacement and cross-reference identification
IKO CF16 and WERB NAKD35 are useful identifiers for this nominal size. The KRV-family legacy row uses NAKD35V. Use these references to narrow the search, then verify the physical interface and ordered configuration before treating the parts as interchangeable.
| EP reference | IKO reference | WERB legacy | Replacement note |
|---|---|---|---|
| EP-KR35 | CF16 | NAKD35 | Standard KR-family reference; confirm ordered outer-surface and lubrication details. |
| EP-KRV35 | CF16 | NAKD35V | KRV-family reference; confirm sealing/guide configuration for the order. |
| EP-KRE35 / EP-KRVE35 | — | — | Eccentric-family naming when an eccentric arrangement is required; confirm e and the complete interface. |
Selection and installation checks
Confirm D* 35 mm, C 18 mm, M16x1.5 thread, B/B1/B2 geometry and the available shoulder/corner clearance.
Inspect the mating track in the context of high-cycle cam motion. A displaced contact band, ridge or local impact mark can indicate an alignment or track problem that should be corrected before EP-KR35 / EP-KRV35 is installed.
The speed reference is 10,000 rpm. Real operating suitability still depends on load, lubrication, temperature, contamination and cycle pattern.
State KR/KRV/KRE/KRVE preference, outer-surface geometry, lubricant/sealing requirement and any inspection/documentation needs in the RFQ.
