Factory Price SK140 Lug-Pattern Excavator Top Roller Carrier Roller for 14-Ton Kobelco SK140-Series.

The SK140 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 SK140 top roller is a critical wear component in the undercarriage system of the Kobelco SK140 excavator, designed to support the track and ensure smooth movement between the sprocket, idler, and track links. Regular replacement of top rollers is essential to maintain excavator performance, as worn rollers can cause increased friction, uneven track wear, and reduced operational efficiency.
