Category: Stud Type Track Roller

Overview

INA NUKR72-A 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.
