The DH300 Top Roller is a precision-engineered component designed for 30-Ton Doosan DH300-series excavators. This lug-pattern carrier roller ensures durability, excellent load-bearing capacity, and smooth operation in demanding construction environments.
The DH300 top roller is a critical wear part in the undercarriage system of DH300-series excavators (including Daewoo DH300, DH300LC-7 models). Its primary function is to support the upper run of the rubber track, reducing friction between the track and excavator frame while ensuring smooth, consistent movement during operation. As a load-bearing component, it withstands repeated vertical and horizontal forces from the track, making durability and precision essential to prevent track slippage, uneven wear, and costly downtime.
