Stud Type Track Roller

EX-WORKS (Incoterms 2020) Seoul, Korea — Buyer arranges freight, duties, and insurance.
INA KR19-PP-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.
Check stud diameter and thread, outer ring profile, eccentric adjustment need, load, speed, and lubrication.
