Track Chains & Rails
Replacement Track Chains and Rails
Track chains, also called track rails, carry the machine weight and provide the moving foundation for a steel-track undercarriage. Correct fit depends on the machine model, serial range, pitch, link count, shoe configuration, and mating sprocket and roller dimensions.
Where Track Chains Are Used
- Excavators and mini excavators
- Crawler dozers and loaders
- Tracked specialty and road-building equipment
Start at the undercarriage parts hub to review the full system. Inspect chains together with rollers, idlers, sprockets, segments, and track shoes because uneven wear can shorten the life of new parts.
How to Identify the Correct Chain
Provide the equipment make, model, serial number, link count, pitch, shoe width, and photos of the current undercarriage. Use the Part Finder when the part number or configuration is uncertain.
Track Chain Selection and Wear
Match the Complete Undercarriage System
Pitch, link design, pin and bushing condition, rail height, and sprocket engagement all matter. Replacing one component without checking the others can cause accelerated wear or poor tracking.
