KR16 needle roller cam follower
EP-KR16 stud type cam follower bearing with 16 mm outside diameter, M6 x 1 metric stud thread and CF6 cross-reference designation.
EP-KR16 moves one step above the smallest follower while keeping a compact overall form. The table gives a 16 mm outside diameter, 11 mm roller width and M6 x 1 stud thread, providing a clear dimensional signature for small automated mechanisms.
Its B1 maximum length is listed as 28.2 mm and the mass as 18 g. These values help distinguish KR16 from a smaller KR13 installation when the roller is partly hidden behind a bracket and only the stud side can be measured directly.
EP-KR16 is listed with D = 16 mm, C = 11 mm, stud diameter 6 mm and M6 x 1 thread. The legacy WERB references shown for this row are NAKD16 and NAKD16V.
Key Specifications
EP-KR16 uses the M6 x 1 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-KR16 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-KR16 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 = 0.25 mm belongs to the related KRE/KRVE execution for EP-KR16. 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-KR16 and CF6 to locate the candidate row, then verify the dimensions that matter on this machine. For this size, thread M6 x 1, 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-KR16 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.
Six-Millimetre Stud Interface and Width Match
A KR16 identification becomes much more reliable when the M6 x 1 thread is checked together with the 6 mm stud diameter. The 16 mm D value confirms the running diameter, while C = 11 mm tells the buyer how much track width is engaged. This combination is more useful than treating CF6 as a stand-alone replacement statement.
KR19 is worth checking when a removed follower measures 11 mm across the roller, because KR16 and KR19 share that C dimension. They do not share the same interface: KR19 increases the outside diameter to 19 mm and uses an M8 x 1.25 thread. The thread gauge therefore resolves a common ambiguity quickly.
The KR16 row shows a limit-speed value of 25,000 rpm and a 0.25 mm eccentric value for the corresponding eccentric execution. If the machine uses adjustment through an eccentric stud, confirm that arrangement from the assembly rather than assuming every KR16 position should be converted to KRE/KRVE.
On compact robot tooling, inspection fixtures or transfer devices, service access may be limited. Record whether the nut can be reached without moving the track, and photograph the contact band on the outer ring if possible. Those observations help separate a simple follower replacement from a rail-alignment or bracket-clearance problem.
Applications for EP-KR16
Industrial robots & compact automation
Small cam paths, transfer mechanisms and fixture motion where a compact stud-mounted follower fits the available envelope.
Semiconductor & electronics equipment
Wafer, inspection and precision handling mechanisms where compact geometry and controlled lubrication access matter.
Machine-tool auxiliary mechanisms
Compact indexing, guide and tool-handling functions where the follower interface must match a defined machine drawing.
Packaging and labelling machinery
Light cam-driven feed, timing and indexing stations with frequent cycles.
Inspection and indexing equipment
Repeatable cam or track motion in gauges, test fixtures and small indexing assemblies.
Linear track and transfer modules
Stud-mounted rolling contact along a rail where track alignment and contact width can be inspected.
EP-KR16 sits between the KR13 and KR19 compact sizes, so the application examples should be read with the M6 mounting interface in mind. Verify that the machine provides the 16 mm roller envelope and enough service access to tighten the stud without forcing the track out of alignment.

Use the neighboring EP-KR13 and EP-KR19 cards as boundary checks for EP-KR16. The roller width alone is not enough: KR19 also shows C = 11 mm, while the outside diameter and stud thread change.

What IKO reference is shown for EP-KR16?
The cross-reference table shows CF6 on the same size row as EP-KR16. 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-KR16 use?
The listed stud thread for EP-KR16 is M6 x 1.
What is the related KRV or eccentric designation?
The paired KRV designation is EP-KRV16. If the machine is designed for eccentric adjustment, the naming convention for the corresponding eccentric executions is EP-KRE16 / EP-KRVE16; the table lists e = 0.25 mm for the size row.
What information should I send for a quote?
When requesting EP-KR16, provide the existing CF6 or KR marking, measured 16 mm outside diameter, 11 mm C width, M6 x 1 stud thread, quantity, track condition and a photo that shows the mounting nut and available axial space.
Get a Quote for EP-KR16
An EP-KR16 quote is easier to review when the M6 x 1 thread and 16 mm running diameter are visible in the same sketch or photo. Add the machine function and quantity so the selection discussion starts from the real interface rather than from a shortened code.
