KR32 cam follower bearing
EP-KR32 stud type cam follower bearing with 32 mm outside diameter, M12 x 1.5 metric stud thread and CF12-1 cross-reference designation.
EP-KR32 retains the M12 x 1.5 stud and 14 mm roller width found on KR30, then increases the outer running diameter to 32 mm. The CF12-1 reference is useful for locating the row, while the diameter measurement confirms which M12 size is actually installed.
Its listed axial dimensions match KR30, including B1 max = 40.2 mm and B2 = 25 mm, while the mass is 90 g. That close dimensional relationship explains why these two models should be compared deliberately during MRO replacement work.
EP-KR32 is listed with D = 32 mm, C = 14 mm, stud diameter 12 mm and M12 x 1.5 thread. The legacy WERB references shown for this row are NAKD32 and NAKD32V.
Key Specifications
EP-KR32 uses the M12 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-KR32 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-KR32 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 = 0.3 mm belongs to the related KRE/KRVE execution for EP-KR32. 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-KR32 and CF12-1 to locate the candidate row, then verify the dimensions that matter on this machine. For this size, thread M12 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-KR32 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.
Two Extra Millimetres at the Running Diameter
If an old follower has an M12 x 1.5 thread, do not stop there. KR32 requires a 32 mm D measurement and C = 14 mm. The KR30 row uses the same thread, stud diameter and width but a 30 mm outer ring. A caliper across the roller is therefore the fastest practical discriminator.
CF12-1 appears on the KR32 line, whereas CF12 appears on KR30. Treat the suffix as an identification hint that should agree with the measured diameter. This approach is especially useful on machines where a previous service replacement may not carry the original brand marking.
The KR32 table row repeats the same 590/450 C/C0 numbers and 14,000 rpm limit-speed listing as KR30. Because the C/C0 unit is absent in the rating table, those figures are not assigned N, kN or another unit here. Any calculation should begin by confirming that missing unit convention.
For track inspection, look at whether the 32 mm roller is contacting across the intended width and whether the mounting face keeps the stud square to the cam. A larger diameter does not correct an angled bracket; visible edge loading should be addressed as an installation issue as well as a bearing replacement.
Applications for EP-KR32
Machine tools & CNC
Guide tracks, indexing mechanisms and auxiliary slides that use a stud-mounted roller against a defined cam or rail.
Industrial automation
Robot fixtures, transfer units and automated mechanisms where compact mounting and repeated cam motion are common.
Packaging machinery
Feeding, folding and indexing functions driven by cams or profiled tracks.
Conveyor track systems
Guided carriers and transfer mechanisms where the outer ring repeatedly follows a rail.
Precision handling equipment
Inspection, electronics and semiconductor-related mechanisms when the selected size and service conditions match.
Indexing and transfer mechanisms
Rotary or linear indexing assemblies where the stud interface and track geometry must be verified together.
When EP-KR32 is considered for an application, the important distinction is not the industry label but the 32 mm outer ring on the shared M12 platform. Check the cam radius, available radial space and contact band before assuming the KR30/KR32 pair can be exchanged.
Related Products and Nearby Sizes
Use EP-KR30 as the first comparison for EP-KR32 because both rows show M12 x 1.5 and C = 14 mm. EP-KR35 then marks the next change to an M16 stud and an 18 mm roller width.

What IKO reference is shown for EP-KR32?
The cross-reference table shows CF12-1 on the same size row as EP-KR32. 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-KR32 use?
The listed stud thread for EP-KR32 is M12 x 1.5.
What is the related KRV or eccentric designation?
The paired KRV designation is EP-KRV32. If the machine is designed for eccentric adjustment, the naming convention for the corresponding eccentric executions is EP-KRE32 / EP-KRVE32; the table lists e = 0.3 mm for the size row.
What information should I send for a quote?
An EP-KR32 enquiry should include the CF12-1 or old code, a confirmed 32 mm roller diameter, 14 mm width, M12 x 1.5 thread, quantity, track profile and photographs that show the mounting face and contact band.
Get a Quote for EP-KR32
Send EP-KR32 requests with a 32 mm D measurement and CF12-1 marking if available. Those details prevent confusion with EP-KR30, which uses the same M12 x 1.5 stud but a smaller outside diameter.
