Industrial automation and robotics can use cam followers in transfer units, indexing fixtures, guided mechanisms and auxiliary robot motion. the application guidance directs attention to the compact EP-KR13 through EP-KR35 sizes and highlights lightweight construction, speed and small packaging. These applications usually benefit from starting with the interface envelope and motion profile rather than selecting by a generic “robot bearing” label.
Compact-motion priorities
Small outer diameter and stud geometry can matter when a follower sits inside a gripper, transfer unit, indexing fixture or compact actuator assembly.
The smaller listed sizes carry higher catalogue speed references. That makes EP-KR13 to EP-KR22 useful dimensional starting points for faster, lighter mechanisms when the actual load permits.
Track alignment, stud seating and consistent contact influence repeatable motion. A replacement should be checked as part of the mechanism, not treated as an isolated rolling element.
Compact EP-KR / EP-KRV range
| EP model | D* (mm) | Stud thread | Speed reference | Automation screening note |
|---|---|---|---|---|
| EP-KR13 / EP-KRV13 | 13 | M5×0.8 | 29,000 rpm | Smallest size in the range; useful where the mechanism envelope is very tight. |
| EP-KR16 / EP-KRV16 | 16 | M6×1 | 25,000 rpm | Compact step up with a larger stud interface. |
| EP-KR19 / EP-KRV19 | 19 | M8×1.25 | 20,000 rpm | Useful in compact transfer or actuator mechanisms. |
| EP-KR22 / EP-KRV22 | 22 | M10×1.25 | 17,000 rpm | Common transition into the mid-size group. |
| EP-KR26 / EP-KRV26 | 26 | M10×1.25 | 17,000 rpm | Larger outer ring while keeping the listed M10×1.25 thread. |
| EP-KR30 / EP-KRV30 | 30 | M12×1.5 | 14,000 rpm | Mid-size option when the mounting envelope grows. |
| EP-KR32 / EP-KRV32 | 32 | M12×1.5 | 14,000 rpm | Larger outer diameter with the same listed thread group as EP-KR30. |
| EP-KR35 / EP-KRV35 | 35 | M16×1.5 | 10,000 rpm | Upper end of the industrial-automation range in the application guidance. |
Integration checks before a new build or retrofit
Confirm D*, outer-ring width, stud thread, stud length and wrench/tool access. Compact automation often fails on a small clearance detail rather than the nominal diameter.
A follower should meet the cam or guide surface evenly through the motion. Include a sketch of the track direction and follower orientation for a retrofit.
For MRO work, send the old marking plus any noise, wear or looseness observed. That helps distinguish a simple dimensional replacement from a mechanism issue.
Describe whether the follower is used in transfer, indexing, guided motion, fixture actuation or robot-support motion, and include cycle rate or speed data where available.
Match the compact follower to the actual mechanism
Send the existing model or target envelope, quantity, D*, stud thread, motion cycle, track orientation and available installation space. We will start with the EP-KR13 to EP-KR35 range and narrow it by real interface conditions.
