Overview
NTN KRV30H/3AS Stud Type Track Roller is a cam follower with an integrated stud and bearing outer ring. It mounts without a separate shaft, saving space while supporting repeated loads in cams, guide rails, and automated handling equipment.
Needle or cylindrical rollers run inside a thick outer ring, while a threaded stud acts as the shaft. Options such as eccentric studs, seals, and lubrication holes improve adjustment and maintenance.
Key features
- Integrated stud for simple mounting
- Thick outer ring for cam and track contact
- Handles repeated shock loads
- Eccentric versions allow position adjustment
Typical applications
- Cam follower mechanisms
- Automated transfer rails
- Packaging and printing machines
- Lifts, doors, and guide systems
Selection guidance
Check stud diameter and thread, outer ring profile, eccentric adjustment need, load, speed, and lubrication.
