KR22 cam follower bearing metric
EP-KR22 stud type cam follower bearing with 22 mm outside diameter, M10 x 1.25 metric stud thread and CF10 cross-reference designation.
EP-KR22 introduces the M10 x 1.25 stud interface in this range. Its 22 mm outside diameter and 12 mm roller width create a size that can be confused with KR26 if the buyer looks only at the thread and axial dimensions.
The row shows B1 max = 36.2 mm, B2 = 23 mm and a mass of 44 g. Those values become useful cross-checks when the outside diameter cannot be measured easily because the follower is still captured inside a track or cam mechanism.
EP-KR22 is listed with D = 22 mm, C = 12 mm, stud diameter 10 mm and M10 x 1.25 thread. The legacy WERB references shown for this row are NAKD22 and NAKD22V.
Key Specifications
EP-KR22 uses the M10 x 1.25 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-KR22 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-KR22 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-KR22. 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-KR22 and CF10 to locate the candidate row, then verify the dimensions that matter on this machine. For this size, thread M10 x 1.25, 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-KR22 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.
Distinguishing KR22 from the Same-Thread KR26
KR22 and KR26 share the listed 10 mm stud diameter, M10 x 1.25 thread, C = 12 mm, G1 = 12 mm and the same principal axial lengths. The decisive dimension between those two rows is the outer running diameter: 22 mm for KR22 versus 26 mm for KR26. That four-millimetre difference should be measured before an order is placed.
The cross-reference entries also differ: KR22 is paired with CF10, while KR26 is paired with CF10-1. Because suffix conventions can vary between brands and executions, use that distinction to find the correct row, then let the measured D value settle the selection.
Both size rows show the same C/C0 numbers and the same 17,000 rpm limit-speed value in the supplied rating table. The load-rating unit is not printed, so those numbers remain unitless on this site. For engineering calculations, confirm the intended unit convention before using them in a life or load comparison.
When KR22 is installed against a narrow cam or guide rail, inspect whether the full 12 mm roller width has been used. A polished band much narrower than the outer ring can signal track-width or alignment issues. Correcting those conditions may be as important as selecting the right M10 follower.
Applications for EP-KR22
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.
EP-KR22 is the smaller of the two M10 x 1.25 rows. In machine tools, automation or packaging equipment, confirm that the track was designed around a 22 mm running diameter rather than assuming the shared M10 stud makes KR26 an equivalent choice.
Related Products and Nearby Sizes
Compare EP-KR22 directly with EP-KR26 because the two rows share the stud thread and many axial dimensions. Add EP-KR19 to the comparison when the removed component sits near the transition from an M8 to an M10 mounting hole.

What IKO reference is shown for EP-KR22?
The cross-reference table shows CF10 on the same size row as EP-KR22. 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-KR22 use?
The listed stud thread for EP-KR22 is M10 x 1.25.
What is the related KRV or eccentric designation?
The paired KRV designation is EP-KRV22. If the machine is designed for eccentric adjustment, the naming convention for the corresponding eccentric executions is EP-KRE22 / EP-KRVE22; the table lists e = 0.3 mm for the size row.
What information should I send for a quote?
For EP-KR22, send the CF10 or existing code, measured 22 mm running diameter, 12 mm width, M10 x 1.25 thread, quantity and a photo of the track. State explicitly if KR26 is also being considered so the 22/26 mm diameter difference can be checked.
Get a Quote for EP-KR22
An EP-KR22 request should include the 22 mm D measurement, because M10 x 1.25 alone does not distinguish it from EP-KR26. A simple caliper photo of the roller diameter is often the fastest way to prevent a same-thread mix-up.
