Description
EP-KR62 / EP-KRV62 is the EVER POWER designation for the 62 mm nominal outside-diameter size in the KR/KRV stud type track roller family. It uses a M24x1.5 stud, an outer-ring width of 29 mm and a speed reference of 6,500 rpm. This size is a practical screening point for machine tools, ATC systems and heavier automated mechanisms.

Dimensions and mounting interface
The 62 mm size marks the move into the M24×1.5 stud group. Confirm mounting-wall thickness, tightening access and the available track width before using it in a retrofit.
| Dimension | Value |
|---|---|
| G1 | 25 mm |
| B max | 30.6 mm |
| B1 max | 80.1 mm |
| B2 | 49.5 mm |
| B3 | 11 mm |
| C1 | 0.8 mm |
| rs min | 1 mm |
At M24 size, the mounting member should be treated as a structural part of the follower system. Check wall thickness, thread engagement, shoulder seating and access for controlled tightening before installation.
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.
Large followers need a centered radial load path through a rigid support. Side thrust or a diagonal wear band should trigger an alignment review rather than an assumption that a heavier follower will solve the problem.
At this M24 size, include the support plate and track structure in the inspection. A rigid-looking follower can still run poorly if the surrounding frame flexes or the contact band is not centered.
Size-specific selection perspective
Where EP-KR62 / EP-KRV62 fits
EP-KR62 / EP-KRV62 starts the M24×1.5 part of the range and is aimed at mechanisms with substantially more mounting space than the medium sizes. Machine-tool and ATC applications in this diameter class benefit from a deliberate check of mounting-wall thickness, stud engagement and the stiffness of the track support. If the follower is being replaced after wear, inspect whether the contact band is centered across the outer ring; off-center wear can indicate a geometry problem that should be corrected first. For new equipment, use the dimensional drawing to reserve service access around the stud and to confirm that the cam or rail can support the intended radial contact path without edge loading.
Use M24 thread engagement and the 62 mm ring envelope as the initial fit check. For machine-tool or ATC duty, follow with support-wall stiffness, track alignment, lubrication access and the measured condition of the old contact surface.
Replacement and cross-reference identification
IKO CF24 and WERB NAKD62 are useful identifiers for this nominal size. The KRV-family legacy row uses NAKD62V. 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-KR62 | CF24 | NAKD62 | Standard KR-family reference; confirm ordered outer-surface and lubrication details. |
| EP-KRV62 | CF24 | NAKD62V | KRV-family reference; confirm sealing/guide configuration for the order. |
| EP-KRE62 / EP-KRVE62 | — | — | Eccentric-family naming when an eccentric arrangement is required; confirm e and the complete interface. |
Selection and installation checks
Confirm D* 62 mm, C 29 mm, M24x1.5 thread, B/B1/B2 geometry and the available shoulder/corner clearance.
Inspect the mating track in the context of machine-tool or heavy cam motion. A displaced contact band, ridge or local impact mark can indicate an alignment or track problem that should be corrected before EP-KR62 / EP-KRV62 is installed.
The speed reference is 6,500 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.
