Product Description
KR62 track roller bearing
EP-KR62 stud type cam follower bearing with 62 mm outside diameter, M24 x 1.5 metric stud thread and CF24 cross-reference designation.
EP-KR62 moves into the M24 x 1.5 stud sizes with a 62 mm outside diameter and 29 mm roller width. It shares its principal dimensions and rating-row values with KR72 except for the larger model’s outside diameter and mass.
B1 max is listed as 80.1 mm and B2 as 49.5 mm, while the KR62 mass is 790 g. These figures help when a large follower cannot be removed immediately and the maintenance team has access to a machine drawing or spare-parts record.
EP-KR62 is listed with D = 62 mm, C = 29 mm, stud diameter 24 mm and M24 x 1.5 thread. The legacy WERB references shown for this row are NAKD62 and NAKD62V.
Key Specifications
EP-KR62 uses the M24 x 1.5 stud interface shown above. Its C and C0 entries remain in the rating table without an added load unit because that unit is not printed in the project size table.
Full Dimension Table
Use the drawing for EP-KR62 to locate D, C, the stud diameter, thread and axial lengths before measuring the removed part. Those interfaces are the primary replacement checks; the cross-reference code should agree with the dimensions rather than override them.
The running-surface note for EP-KR62 allows cylindrical or spherical execution depending on design. Confirm which surface profile the machine requires before choosing between the KR and KRV routes.

Eccentric value e = 0.4 mm belongs to the related KRE/KRVE execution for EP-KR62. The C/C0 columns are reproduced without a unit because none is printed in the table; confirm the unit convention before calculation.
Selection and Replacement Notes
Use EP-KR62 and CF24 to locate the candidate row, then verify the dimensions that matter on this machine. For this size, thread M24 x 1.5, roller diameter and roller width should agree with the removed follower or drawing before running-surface and lubrication details are reviewed.
Inspect the contact band while EP-KR62 is still in the mechanism if access allows. A centred, even band supports the size check; edge polishing or grooving is a reason to examine the rail, bracket and stud alignment instead of assuming a new follower alone will resolve the wear.
M24 Stud Pair: Establish the 62 mm Diameter
KR62 and KR72 both use a 24 mm stud, M24 x 1.5 thread, C = 29 mm and identical listed axial dimensions. The outside diameter is the main selector between them: 62 mm for KR62 versus 72 mm for KR72. A ten-millimetre difference is large enough that it should be verified directly before procurement.
The IKO reference changes from CF24 on KR62 to CF24-1 on KR72. Use those codes to navigate drawings and purchasing records, then check D so that a missing suffix does not lead to the wrong roller envelope. The mass values, 790 g and 1040 g respectively, offer a secondary distinction if a documented weight is available.
The rating row gives 6,500 rpm as the limit-speed value and e = 0.40 mm for the corresponding eccentric execution. On larger machinery, actual speed may be modest while track loads and impact dominate. Include duty, track material and lubrication method in the enquiry rather than evaluating the follower from the speed figure alone.
Large studs need sound support. Inspect the mounting face for fretting or distortion and check whether the track loads the centre of the roller. A visible edge-contact pattern can indicate bracket deflection or misalignment, which should be corrected before a replacement KR62 is expected to run evenly.
Applications for EP-KR62
Material handling & heavy conveyors
Large track-guided carriers and transfer systems where the follower has to fit a larger stud and roller envelope.
Heavy indexing & cam mechanisms
Industrial indexing mechanisms and cam drives with larger track geometry and mounting interfaces.
Large machine-tool mechanisms
Heavy auxiliary guide or indexing functions where the mounting face and stud support are substantial.
Large packaging & converting equipment
Cam-driven stations using larger followers where track wear and service access need review.
Industrial rail-following systems
General machinery that uses a large stud-mounted roller against a defined track.
Automation & transfer equipment
Larger automated transfer mechanisms when the measured interface and duty suit the selected size.
EP-KR62 belongs in larger material-handling, indexing or machine mechanisms only after the 62 mm running diameter is established. Because KR72 shares the M24 mounting platform, machine size or application description by itself is not enough for identification.
Related Products and Nearby Sizes
Compare EP-KR62 directly with EP-KR72 to resolve the M24 same-thread pair, and use EP-KR52 as the lower boundary where the stud drops to M20 and the roller width returns to 24 mm.

What IKO reference is shown for EP-KR62?
The cross-reference table shows CF24 on the same size row as EP-KR62. Use that designation as a cross-reference search aid and verify D, C, stud thread, running-surface profile and any suffix-specific execution before replacement.
What thread does EP-KR62 use?
The listed stud thread for EP-KR62 is M24 x 1.5.
What is the related KRV or eccentric designation?
The paired KRV designation is EP-KRV62. If the machine is designed for eccentric adjustment, the naming convention for the corresponding eccentric executions is EP-KRE62 / EP-KRVE62; the table lists e = 0.4 mm for the size row.
What information should I send for a quote?
For EP-KR62, send CF24 or the existing code, 62 mm D, 29 mm C, M24 x 1.5 thread, quantity, mounting-face photos, track width and operating duty. Mention any eccentric setting or recurrent edge wear.

An EP-KR62 replacement enquiry should include the 62 mm roller measurement and a view of the M24 mounting face. Those details distinguish the part from EP-KR72 and help identify alignment or support issues before installation.
