FridayParts understands that your heavy machinery’s stability and traction depend on its undercarriage parts. Whether you operate excavators, dozers, or track loaders, a durable undercarriage ensures efficiency on every job site. Over time, undercarriage wear is inevitable — especially in rock, mud, or uneven terrain. Uneven track tension, excessive vibration, or slippage are the main symptoms indicating it’s time to inspect or replace worn undercarriage parts before larger failures occur.
More than half of your tracked machine’s lifetime costs come from the undercarriage, making quality replacement a smart investment. Therefore, FridaParts provides OEM-quality chassis parts, which can save you high maintenance costs while ensuring quality.
The undercarriage parts form a complete track system that propels and stabilizes machinery. Each part handles a specific task:
| Component | Function | Typical Replacement Interval | FridayParts Advantage |
| Track Roller | Supports track load | 1,500–2,000 hours | Enhanced sealing & wear resistance |
| Carrier Roller | Guides the upper track | Every 2–3 years | Precision heat treatment for strength |
| Front Idler | Maintains tension | 2,000–4,000 hours | Smooth tracking & noise reduction |
| Sprocket | Drives track | 2,500 hours | OEM‑level fit & finish |
| Bucket Tooth | Digs & breaks ground | 500–1,000 hours | Strong penetration & easy installation |
| Chain Guard | Protects the chain system | 4,000 hours | High impact protection |
