Product Overview
The carrier roller supports the upper run of the track and helps keep the track chain aligned as the machine travels. A seized or worn top roller can increase drag, noise and track wear.
Undercarriage catalogs list AX30-family top rollers under Hitachi/Airman-style references such as 4392416 depending on production version. Measure the original roller before ordering.
