Product Overview
The Track Roller — also called Bottom Roller or Lower Roller — is the load-bearing roller mounted under the track frame of the Liugong CLG936 excavator. It carries the full machine weight, keeps the track chain aligned, and transfers the load evenly to the ground. A worn or seized track roller causes track misalignment, accelerated wear on the chain and sprocket, and expensive downtime on the jobsite. Our rollers are manufactured to the original dimensional drawings of the CLG936 undercarriage, covering the CLG936, CLG936D and LG936 series for a direct, bolt-on replacement.

Why Trust Our Undercarriage Solutions?
For a 36-ton class excavator like the CLG936, every track roller carries a significant share of the machine's total weight — a failed roller means track misalignment, extra wear on the entire undercarriage and expensive downtime. Every roller we produce is 100% inspected for hardness, dimensional accuracy and sealing quality before shipment. Our goal is to deliver genuine-compatible durability at a competitive price, backed by a clear warranty. Contact us with your machine serial number, current part number and position (left/right, SF/DF) to confirm the correct fitment.
