Description
EP-KR16 / EP-KRV16 is the EVER POWER designation for the 16 mm nominal outside-diameter size in the KR/KRV stud type track roller family. It uses a M6x1 stud, an outer-ring width of 11 mm and a speed reference of 25,000 rpm. This size is a practical screening point for bond-head mechanisms, small electronics equipment and compact automation.

Dimensions and mounting interface
EP-KR16 keeps a small 16 mm outside diameter while stepping to an M6×1 stud. This can help when the mechanism needs slightly more mounting section than the smallest size without moving into the larger M8/M10 group.
| Dimension | Value |
|---|---|
| G1 | 8 mm |
| B max | 12.2 mm |
| B1 max | 28.2 mm |
| B2 | 16 mm |
| B3 | — |
| C1 | 0.6 mm |
| rs min | 0.3 mm |
Direct stud mounting suits compact frames, provided the M6 thread is supported by adequate material. Compare the shoulder and axial lengths with the existing bracket and keep tightening access clear of nearby sensors or moving members.
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.
Design the contact path around radial loading of the outer ring. Side thrust from a misaligned compact mechanism should be corrected at the guide or track instead of being accepted as an assumed bearing duty.
When comparing this size with EP-KR13, focus on the changed stud and support geometry rather than assuming the diameter step is the only difference. The bracket and track should be measured as one interface.
Size-specific selection perspective
Where EP-KR16 / EP-KRV16 fits
The 16 mm follower is often considered where a compact mechanism needs a little more mounting section than the smallest size while remaining in a low-inertia package. Bond-head and electronics automation layouts can be sensitive to runout, alignment and the stiffness of the support into which the M6 stud is installed. For replacement work, compare the outer-ring width, shoulder position and usable stud length before relying on the model marking. For a new design, review the cam or rail surface together with cycle rate and lubrication access. That sequence is more useful than choosing by outside diameter alone because the mounting interface governs how the follower is supported.
Screen the 16 mm size by matching its M6 stud and outer-ring position to the mechanism, then review acceleration, lubrication and environmental cleanliness. In compact equipment, the quality of alignment usually matters more than choosing from a broad size range by code alone.
Replacement and cross-reference identification
IKO CF6 and WERB NAKD16 are useful identifiers for this nominal size. The KRV-family legacy row uses NAKD16V. 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-KR16 | CF6 | NAKD16 | Standard KR-family reference; confirm ordered outer-surface and lubrication details. |
| EP-KRV16 | CF6 | NAKD16V | KRV-family reference; confirm sealing/guide configuration for the order. |
| EP-KRE16 / EP-KRVE16 | — | — | Eccentric-family naming when an eccentric arrangement is required; confirm e and the complete interface. |
Selection and installation checks
Confirm D* 16 mm, C 11 mm, M6x1 thread, B/B1/B2 geometry and the available shoulder/corner clearance.
Inspect the mating track in the context of compact precision motion. A displaced contact band, ridge or local impact mark can indicate an alignment or track problem that should be corrected before EP-KR16 / EP-KRV16 is installed.
The speed reference is 25,000 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.
