Cam Follower Bearings for Conveyor and Material Handling Systems
cam follower conveyor track roller / stud type bearing conveyor system
Conveyors and material-handling machines use stud-mounted followers in track guidance, lift-and-transfer modules, indexing stations and moving fixtures. These mechanisms can combine repeated loading with dust, fibres, packaging debris or process residue. Track condition and service access therefore matter just as much as the nominal bearing code.
EP-KR30, EP-KR40, EP-KR47 and EP-KR52 are useful mid-to-large references for many track mechanisms when their dimensions match the machine. For heavier or larger envelopes, EP-KR62 through EP-KR90 provide additional size options. An eccentric KRE/KRVE-style execution can be considered when the mechanism is designed for clearance adjustment.

Typical Mechanisms
Track-Guided Carriers
Rollers following a rail or cam path on pallet, carrier and transfer systems.
Lift-and-Transfer Modules
Stud-mounted rolling contact in mechanisms that raise, lower or shift workpieces between conveyor levels.
Indexing and Stop Stations
Repeated cam-driven positioning where impact, reversal and mounting support should be reviewed.
Suspended and Accumulation Mechanisms
Guided motion in conveyor modules where contamination and later service access can be significant.
What to Check Before Selecting
| Selection check | Why it matters |
|---|---|
| Track material and finish | The outer ring and track form one contact system, so a worn or damaged rail can quickly mark a new follower. |
| Contamination and cleaning | Dust, fibres and product debris can change lubrication and inspection intervals. |
| Stud support and load direction | Larger followers need a rigid mounting structure that supports the stud close to the loaded section. |
| Clearance adjustment | If the machine uses an eccentric follower to set rail clearance, record the required offset and adjustment direction. |
Recommended Size References
EP-KR30 / EP-KR40 / EP-KR47 / EP-KR52 are practical catalogue references for many conveyor track mechanisms. Verify the measured interface and actual duty; for larger structures, compare EP-KR62 through EP-KR90 as needed.

View specificationsTrack Inspection and Service Access
A new follower will run on the existing track, so inspect the rail before replacement. Grooves, dents, edge polishing or packed debris can reproduce the same contact problem on the new part. Check the mounting face and stud support at the same time.
For mechanisms that use eccentric adjustment, send the existing follower marking or a dimensioned sketch. The eccentric offset must work with the mounting hole, available wrench access and the direction in which clearance needs to be adjusted.
Application FAQ
Which sizes are useful for conveyor track mechanisms?
EP-KR30, EP-KR40, EP-KR47 and EP-KR52 cover a useful mid-to-large range, while EP-KR62 to EP-KR90 provide larger options. Dimensions and duty decide the final model.
When should an eccentric execution be considered?
Use an eccentric execution only when the machine is designed to adjust follower position or track clearance. Include the required offset and mounting geometry with the enquiry.
