Product range
One series, clear size choices.
Start with the outside diameter and stud thread you need, then check width, stud geometry, speed and the mating track. EP-KR and EP-KRV references are shown together so replacement work stays easy to navigate.
Dimensions Before Model Names
Use D, C, D1, thread, G1, B/B1/B2/B3, C1 and minimum corner radius as practical checkpoints.

Cross-Reference Support
Use legacy CF and NAKD designations as search aids, then confirm the physical interface and ordered configuration.
Open cross reference →Engineering first
A cam follower is part of a motion interface, not an isolated part number.
The outer ring runs against a mating track or cam. That makes track condition, mounting, alignment, lubrication and repeated-cycle behavior part of selection. In replacement projects, we recommend checking the physical dimensions instead of assuming two catalog names are identical.
Applications
Where track rollers earn their place.
They are used where a compact rolling element follows a cam, guide or track. The operating questions change with the machine, so each application page focuses on duty, environment and maintenance instead of repeating the same product copy.

Motion architecture
Track roller or linear guideway?
They solve different problems. A stud type track roller follows a mating surface with a rotating outer ring; a linear guideway uses a rail-and-block architecture for constrained linear motion. The choice starts with the mechanism, load path, accuracy need and space envelope.
