Product Description
The E120B Top Roller is Kubota's compact powerhouse component designed for excavators in demanding Australian projects. This precision-engineered bottom roller ensures durability, excellent load-bearing capacity, and smooth operation in compact construction machinery.The E120B top roller is a critical undercarriage component designed for compact excavators, primarily serving to support the upper run of the rubber track and reduce friction between the track and machine frame. This ensures smooth, consistent movement during operation and helps distribute the machine’s weight evenly to prevent track slippage or uneven wear. As a key wear part, regular inspection and replacement of the top roller are essential to maintain undercarriage performance and extend the lifespan of the excavator.
