If you’re in the construction business, you already know the track roller is not just “another part.” It’s one of the most important components keeping your excavator running smoothly, especially under tough working conditions in the U.S.
So, how do you make sure you’re buying the right one? Let’s break it down.
It sounds obvious, but you’d be surprised how many people order the wrong parts. Start by confirming:
Brand & Model (Komatsu PC200, CAT E320, Hitachi EX200-5, etc.)
Undercarriage type
Number of track rollers per side
If you get this wrong, the roller might not fit, or it might cause premature wear. No one wants that headache.
Every excavator has different roller dimensions, so check:
Diameter & width
Bolt hole spacing
Bushing type (single flange or double flange)
Material & hardness grade
Here’s the thing — for heavy-duty work like quarry or demolition, you want forged steel with deep quench hardening. This improves wear life big time.
OEM parts are made by the machine’s original manufacturer, but they come at a premium. Aftermarket Chinese suppliers offer competitive options, especially when they follow ISO-certified production and full QC inspection.
A good China manufacturer can match OEM performance at a fraction of the cost, making it ideal for fleet owners or rental companies.
Reputable Chinese suppliers will:
Provide material test reports
Perform crack detection & hardness checks
Offer at least 12 months warranty on rollers
If your supplier can’t provide these, think twice.
For U.S. buyers, sea freight from China takes around 20–30 days, plus production time. Plan ahead so you’re not left waiting with idle machines.
Choosing the right track roller isn’t rocket science — but it’s a decision that can save you thousands in repair costs. The key? Get your specs right, vet your supplier, and don’t settle for low-quality parts.
And yeah, don’t wait until the roller literally falls off — that’s too late.
