Product Description
The D65 Top Roller is a precision-engineered component designed for 6.5-ton excavators, ensuring durability, excellent load-bearing capacity, and smooth operation in demanding construction environments.
This vital undercarriage component for Komatsu D65 bulldozers maintains optimal track alignment, reduces friction between the track chain and rollers, and supports machine weight during operation. Working with idlers, sprockets, and carrier rollers, it ensures stability and efficiency in heavy-duty tasks like digging, pushing, and traversing rough terrain.
