If you read our last post about why quality excavator supporting products matter, you already understand how vital these parts are. But now comes the big question — how do you choose the right ones?
Don’t worry, we’ve got you covered. Let’s walk through some key factors that will help you make the best decision for your machine.
Different excavators have different specifications. Whether you’re using Komatsu PC200, CAT E320, or Hitachi EX200-5, always confirm the exact part number and tooth or spline count.
Even a small mismatch in design can cause big trouble later — trust me, it happens more often than you think.
Good supporting parts start with good steel. Look for components that are:
Forged, not cast
Tempered for strength
Machined with precision
High-end Chinese factories (like ours) use CNC machining, forging lines up to 4000 tons, and heat treatment systems to ensure toughness and durability.
Cheap materials? They might work at first, but they don’t last. And yes, that’s a big headache later.
A reliable China manufacturer and supplier should have:
Crack detection
Quench depth testing
Metallographic analysis
These ensure every roller, flange, and gear meets the OEM standard. So before placing an order, don’t be afraid to ask for test reports — it’s your right as a buyer.
You want a supplier that doesn’t just sell parts — but supports you afterward. Whether it’s a Lonking, SDLG, or XGMA model, your supplier should provide guidance and replacement advice.
That’s why long-term cooperation with trusted manufacturers is worth it. It saves time and avoids lots of headaches down the road.
Choosing excavator supporting products isn’t rocket science, but it does require care. The right supplier ensures long-lasting performance, the wrong one brings endless repair bills.
As we mentioned in our previous blog, quality and precision are key. So, take your time, ask questions, and partner with an experienced China factory and exporter. You’ll thank yourself later — seriously.
