When you're operating excavators on rough terrain day after day, the undercarriage takes the heaviest beating. But how do you know when to replace parts like track rollers, carrier rollers, or idler wheels?
Let’s be real — waiting too long can wreck your machine (and your wallet). Here's how to stay ahead.
Don’t ignore these red flags:
Excessive vibration or noise when operating
Uneven wear on tracks or rollers
Oil leaks from the track roller seals
Loose track tension even after adjustment
Cracks or chips on the sprockets or supporting shafts
Here’s the deal — ignoring early symptoms can lead to chain reaction failures. One worn-out roller mess up the track tension, which then wears out the sprockets faster. It’s like a domino effect.
There’s no one-size-fits-all, but here's a general idea:
Track rollers: Every 2,000 – 3,000 hours
Carrier rollers & idlers: 3,000 – 4,000 hours
Sprockets & links: Depending on wear level, around 4,000 hours
That said, rougher conditions mean faster wear — it ain't rocket science.
Well, price is a biggie — but that’s not the only thing. Top-level Chinese factories like Liancheng Machinery offer:
Forged steel with quenching & tempering treatment
OEM compatibility with brands like Komatsu, Hitachi, CAT, and SDLG
Strict QC including hardness testing, crack inspection, and metallographic analysis
Fast lead time + B2B support for bulk orders
More and more U.S. contractors are turning to China suppliers for reliable, affordable, and well-made components.
Don’t wait for a complete breakdown. If you're seeing uneven wear or hearing odd noises, it's time to check your undercarriage parts — better safe than sorry.
