Product Overview

The Track Roller, also known as Bottom Roller or Lower Roller, is an important undercarriage component installed beneath the track frame of Sumitomo crawler excavators.

The compatible roller for SH55, SH60 and SH80 supports the machine operating weight, guides the track chain and helps maintain correct crawler alignment during travelling and excavation.

Track rollers operate in demanding conditions involving:

• Continuous machine loading
• Uneven terrain impact
• Soil and gravel abrasion
• Mud and water contamination
• Repeated travelling and excavation loads

A worn or damaged track roller may cause:

• Track chain misalignment
• Increased travelling vibration
• Abnormal track noise
• Uneven track wear
• Accelerated sprocket and idler wear
• Increased maintenance costs and downtime

Our Sumitomo SH55/SH60/SH80 track rollers are manufactured using professional undercarriage production processes to provide a reliable aftermarket replacement solution for equipment dealers, repair workshops and machine owners.
