When it comes to keeping your excavator or bulldozer moving smoothly across rugged terrain, few parts are as critical as the track roller. This small but mighty component supports the entire weight of your machine and guides the track chain to stay aligned—day in and day out.
Whether you’re operating a Komatsu PC200 in California or a CAT D6 in Texas, having high-quality track rollers is essential for uptime and performance. So let’s dive into what they are, how they work, and where to find the right track roller supplier—especially if you're looking for cost-effective options from China.
A track roller, sometimes called a bottom roller, is a part of the undercarriage system found on tracked equipment like excavators, bulldozers, and crawler loaders. It sits beneath the machine and rolls along the track link, supporting the machine’s weight while maintaining track tension and alignment.
There are generally two types:
Single-flange rollers – mostly used on smaller or narrow track frames
Double-flange rollers – more stable, often used for medium and heavy machinery
Without a properly functioning track roller, your entire undercarriage system could wear unevenly—or worse, derail during operation. And nobody got time for that.
Track rollers are under constant stress, which means they eventually wear out. Here are some red flags to watch for:
Excessive vibration during movement
Cracks, oil leaks, or worn flanges
Uneven track tension
Noisy operation or binding sounds
If you ignore these signs, you're not only risking downtime—but also potential damage to other parts like the track chain or sprocket. That’s gonna cost way more in the long run.
U.S. contractors and machinery dealers are increasingly turning to Chinese track roller manufacturers—and for good reason. Chinese factories like Jinjiang Anhai Liancheng Machinery Co., Ltd. have made huge improvements in quality, automation, and heat treatment technology over the past decade.
Here’s what makes a China track roller supplier a smart move:
🏭 In-house forging and CNC machining for exact tolerances
🔥 Induction hardening of roller surfaces for wear resistance (HRC 55-60)
⚙️ Grease-sealed + floating bushing designs to extend lifespan
📦 OEM compatibility with Komatsu, Hitachi, CAT, SANY, Volvo, SDLG, and more
💸 Lower cost per unit with flexible MOQ and fast export service
We manufacture hundreds of excavator and bulldozer track roller models, with strict quality checks including hardness testing, concentricity, and crack inspection.
Our rollers don’t just look good—they roll hard for thousands of hours.
Not all track rollers are made equal. Before you make a purchase, ask your supplier these questions:
What material is used—casting or forged alloy steel?
Is the roller heat treated? What hardness is achieved?
Is the internal seal greased and pressure-tested?
Can they provide exact drawings or OEM part numbers?
What’s the delivery time to the U.S.?
We has supply track roller to more than 30 countries—and yes, that grammar was on purpose 😉
