Factory Price D41 Lug Pattern Excavator Track Roller Bottom Roller

The D41 Track 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 D41 Track Roller is a vital wear part in the undercarriage system of bulldozers, specifically designed for models like the Komatsu D41-3, D41-6, and other bulldozers sharing the same track chain specifications. Its primary function is to support the machine's weight, guide the track chain along its correct path, and absorb shocks from uneven terrain—ensuring stability and efficiency during heavy-duty tasks like digging, pushing, and traversing rough ground. Proper maintenance of the D41 Track Roller is essential to minimize downtime and extend the lifespan of the undercarriage.
