Replacement OEM Track Roller Undercarriage Parts For Heavy Duty Excavator Bulldozer Loader

Track roller, also known as bottom roller or lower roller, is a core undercarriage component designed for crawler excavators, bulldozers, loaders and other construction machinery. Made of high-strength alloy steel and adopting precision forging and integral heat treatment technology, our track roller features high wear resistance, strong impact resistance and stable load-bearing performance.

Strictly manufactured with OEM standard dimensions, our track roller perfectly matches various mainstream machinery brands. It effectively supports the weight of the equipment, keeps the track running smoothly, reduces friction and vibration during operation, and greatly extends the service life of the entire undercarriage system.

How to select a suitable track roller for your excavator/bulldozer/loader ?

Provide us the track roller part number or excavator model if you know it. If you don't know it, how to select a right track roller?

Tonnage matching:

1-3 ton micro excavator: need 4-6 pcs of track roller, single wheel weight ≤ 15kg;

5-8 ton small excavator: need 6-8 pcs of track roller, single wheel weight 20-35kg;

15-25 ton medium excavator: need 8-10 pcs of track roller, single wheel weight 40-70kg;

30 ton and above large excavator: 10-12 pcs of track roller, single wheel weight ≥ 80kg

Track pitch matching: The track pitch and tread width of the supporting wheels must be consistent with the track plate pitch and width - incorrect track pitch can easily cause derailment, narrow tread can easily fracture the track plate, and wide tread can increase frictional resistance

Chassis structure: Match the installation hole positions, axle diameters, and center distances of X-shaped and H-shaped chassis to avoid installation failure
