Heavy Equipment Undercarriage Parts
Undercarriage Parts for Tracked Equipment
The undercarriage carries machine weight, transfers power to the ground, and works continuously in dirt, rock, mud, and abrasive material. Construction Parts PNW helps equipment owners and maintenance teams identify replacement undercarriage parts for excavators, dozers, compact equipment, and other tracked machines.
Main Undercarriage Components
- Track chains and rail assemblies
- Bottom rollers and carrier rollers
- Front idlers and recoil-related components
- Sprockets and segments
- Track shoes, pads, and track groups
- Grouser bars and related wear components where available
Availability varies by machine and component. Browse the undercarriage product catalog or submit machine information for parts that are not displayed online.
What Causes Undercarriage Wear?
Ground conditions, machine alignment, track tension, travel speed, packing, side loading, and operating technique affect service life. Inspect components as a system because uneven wear can shorten the life of newly installed parts.
Related Tracked Equipment Parts
For compact tracked machines, compare rubber tracks and rubber track pads. You can also browse the heavy equipment parts catalog or use the Part Finder for machine-specific assistance.
Common Questions
What information helps identify undercarriage parts?
Provide the manufacturer, model, serial number, component needed, measurements, and photos. Part numbers stamped on the current component are especially useful.
Should worn undercarriage components be inspected together?
Yes. Chains, rollers, idlers, sprockets, and shoes wear together. Reviewing the full system helps avoid pairing a new component with excessively worn mating parts.

Reduce Downtime with Accurate Machine Information
Undercarriage components can vary by serial range, machine configuration, and track setup. Share complete machine details so the parts team can compare compatible options and availability.
If the exact part is not shown online, use the Part Finder instead of guessing from appearance alone.
