Product Overview
Track Roller Bearings
Yoke type and stud type track rollers for cam drives, conveyors, guideways and heavy-duty automation.
Yoke Type and Stud Type Track Roller Bearings
Track rollers use a thick-section outer ring to run directly on tracks, cams and guide surfaces. We support full-complement, caged, sealed, crowned and cylindrical outer-ring designs.
Popular Track Roller Series
- NNTR and RSU double-row yoke track rollers
- NUTR and PWTR full-complement yoke rollers
- NUKR, NUKRE, KR, KRV and CF stud type cam followers
- NATR and NATV needle roller track rollers
- LFR profiled outer-ring track rollers

Inspection records
Request dimensional, marking, packing or supplier-document checks with the RFQ. Availability is confirmed before order placement.
Factory and equipment media
Only dated media supplied by the selected manufacturing partner or captured during the relevant inspection is used as evidence.
Customer applications
Cases are published only with permission or in anonymized form using verified order and application facts.
