EP-KR / EP-KRV stud type track rollers
The live catalogue follows the KR/KRV size progression from 13 mm through 90 mm. Each buyer-facing model uses the EP- prefix while retaining the original dimensional values. A model page is useful when you already know the size; the series page is better when you are still comparing outside diameter, thread and stud geometry.
How to start a selection
Match the mating-track diameter and physical envelope first. Check the stud thread, B/B1/B2/B3 dimensions, speed reference and access for mounting. If the existing part only shows a CF or NAKD designation, use the cross-reference page to find a candidate EP size, then verify dimensions before ordering.
The basic-load table does not state the unit for its C / C0 values. Those figures are intentionally not published as load ratings on this site until the unit and ordered configuration are confirmed.
