Product Description
KR35 needle roller track roller
EP-KR35 stud type cam follower bearing with 35 mm outside diameter, M16 x 1.5 metric stud thread and CF16 cross-reference designation.
EP-KR35 steps away from the M12 pair to a 16 mm stud with M16 x 1.5 thread. The roller outside diameter is 35 mm and C is 18 mm, creating a clear interface transition before the larger KR40 size.
The drawing table lists B1 max = 52.1 mm, B2 = 32.5 mm and B3 = 8 mm, while the rating table lists a mass of 169 g. These dimensions can be checked against a machine drawing when service access prevents a complete measurement in place.
EP-KR35 is listed with D = 35 mm, C = 18 mm, stud diameter 16 mm and M16 x 1.5 thread. The legacy WERB references shown for this row are NAKD35 and NAKD35V.
Key Specifications
EP-KR35 uses the M16 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-KR35 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-KR35 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 = 0.35 mm belongs to the related KRE/KRVE execution for EP-KR35. 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-KR35 and CF16 to locate the candidate row, then verify the dimensions that matter on this machine. For this size, thread M16 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-KR35 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.
M16 Mounting Step and Eighteen-Millimetre Track Width
KR35 is identified by the combined 35 mm running diameter, 18 mm roller width and M16 x 1.5 thread. This is a larger jump in stud size than the change from KR30 to KR32, so the mounting-hole and nut arrangement usually provide a useful visual clue even before the component is removed.
The next KR40 row moves to a 40 mm outer ring, 20 mm C width and M18 x 1.5 thread. Although both use a 1.5 mm thread pitch, the nominal thread diameter changes. Recording the full thread designation avoids the common mistake of treating pitch alone as the mounting specification.
KR35 lists e = 0.35 mm for the eccentric counterpart and a 10,000 rpm limit-speed figure. For printing, packaging or indexing equipment, note whether the follower position is used to set cam engagement. If adjustment is part of the machine setup, include that requirement in the RFQ rather than ordering only by KR35.
A mid-size follower also warrants a close look at the mounting face. Rust fretting, witness marks or a contact band at one outer-ring edge can reveal movement or angular error in the bracket. Replacing the bearing without checking those signs may leave the original cause of uneven track contact unchanged.
Applications for EP-KR35
Conveyor & material handling
Track-guided carriers, transfer stations and repeated material movement with accessible rail inspection.
Printing & packaging machinery
Cam-driven timing, folding, registration and transfer functions with medium-size follower envelopes.
Machine tools & production equipment
Indexing, guide and fixture mechanisms where rigid stud support and a clean contact band are important.
Indexing tables & cam drives
Repeated cam contact in machinery that cycles between defined positions.
Automation transfer systems
Larger transfer and fixture mechanisms that use stud-mounted rollers on a track.
General industrial track rollers
Rail-following mechanisms where D, C, thread and outer-surface profile are checked from a drawing or removed part.
EP-KR35 application review should start from its M16 x 1.5 stud and 35 mm roller rather than from a generic “mid-size” description. Those dimensions make it easier to decide whether a machine-tool, cam drive or conveyor position actually belongs in this row.

What IKO reference is shown for EP-KR35?
The cross-reference table shows CF16 on the same size row as EP-KR35. 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-KR35 use?
The listed stud thread for EP-KR35 is M16 x 1.5.
What is the related KRV or eccentric designation?
The paired KRV designation is EP-KRV35. If the machine is designed for eccentric adjustment, the naming convention for the corresponding eccentric executions is EP-KRE35 / EP-KRVE35; the table lists e = 0.35 mm for the size row.
What information should I send for a quote?
For EP-KR35, provide the CF16 reference if present, 35 mm D, 18 mm C, M16 x 1.5 thread, quantity, mounting-face condition and any eccentric-adjustment requirement. A photo of the cam path is useful for reviewing contact width.
Get a Quote for EP-KR35
An EP-KR35 quotation request should identify the M16 x 1.5 stud and 35 mm roller together. Include any signs of edge loading or bracket movement so the discussion covers installation condition as well as the replacement code.
