ZF Axle Maintenance: The Overlooked Critical Service for Mining Loaders
By TIANJIN XIAOHANG CONSTRUCTION MACHINERY CO.,LTD – Complete Drivetrain Solutions


🛑 Introduction: It’s Not Just About the Gearbox
When people think “ZF,” they usually think about the transmission. But for mining loaders and heavy graders (like the XCMG GR series or LiuGong 856H), the ZF Axles (AP and BP Series) bear the brunt of the load.
Search data shows that “Wet brake failure” and “Axle overheating” are top concerns for mine operators in 2025. Ignoring axle maintenance is the fastest way to turn a productive machine into a parked statue.
I. The Critical Components: Wet Multi-Disc Brakes
ZF axles use a sophisticated wet brake system housed inside the axle hub.
- The Failure Point: If the specialized axle oil isn’t changed, or if inferior friction discs are used, the braking material disintegrates.
- The Consequence: This debris travels through the axle oil, destroying the expensive planetary gears and differential.
- 👉 Deep Dive: Just like transmission clutches, axle brakes require specific friction materials. Ensure you choose [Genuine vs. “OEM Quality”: The Truth About Friction Materials] to avoid dangerous brake fade.
II. The “Wheel End” Vulnerability
The Wheel Hub (Final Drive) operates in the worst conditions—mud, sand, and water.
- The Seal Risk: The Cassette Seal (Hub Seal) is the only barrier between your gears and the dirt. Once this seal fails, water enters, and the planetary gears will grind to dust within days.
- Our Solution: We stock complete ZF Axle Overhaul Kits, including high-performance Hub Seals and Planetary Pins, ready for immediate shipment.
III. One Supplier, Full Drivetrain
Why split your orders between multiple suppliers? Tianjin Xiaohang is your one-stop source for both Transmission AND Axle parts. We verify compatibility between your gearbox output and axle input to ensure the whole drivetrain sings in harmony.
- 👉 Deep Dive: Mining environments are tough and downtime is expensive. See how we helped a South American copper mine recover from a critical axle failure in our [Case Study: Saving a Mine 3 Weeks of Downtime].
💡 Summary: Inspect Your Axles Today
Don’t wait for a grinding noise. Regular replacement of axle seals and brake discs is the cheapest insurance you can buy.
