275101789 Brake Disc For XCMG Loader

As a key cast steel component in the drive axle system of XCMG loaders, the 275101789 brake disc is custom-developed for mainstream 50-60 ton models (such as the XCMG LW500KV and LW600FV). Leveraging high-strength materials and precision craftsmanship, it serves as a key safety feature in heavy-duty applications such as mining and infrastructure construction.

The 275101789 brake disc strictly adheres to the original design specifications of XCMG loaders, achieving a 1:1 replica of key dimensions and mounting holes. It can be directly replaced with the original factory part without any additional modification or adjustment. Passing compatibility testing by the XCMG Engineering Machinery Research Institute, it seamlessly integrates with the original factory brake caliper and hydraulic system, ensuring consistent and stable braking response. It meets the drive axle braking requirements of XCMG loaders across the entire range of heavy-duty models 50 tons and above.

1. High-Temperature, Anti-Fade Material

The 275101789 brake disc utilizes a low-alloy, high-strength cast steel base material. Through a comprehensive heat treatment and surface nitriding process, it forms a wear-resistant layer with a hardness of HV350-400. This effectively prevents common thermal fade issues above 700°C during continuous downhill braking or heavy-load sudden braking, maintaining over 90% braking efficiency.

2. Balanced Lightweight and Wear Resistance

The 275101789 brake disc utilizes topological optimization to reduce the thickness of the non-stressed areas, achieving a 12% reduction in unsprung mass while maintaining strength. This reduces wheel bounce and improves grip. The braking surface features a spiral groove design with high-density heat dissipation channels.
3. Ultra-Long Service Life Design

Thanks to precise metallographic structure control and surface hardening treatment, the 275101789 brake disc boasts a service life exceeding twice that of traditional brake discs under standard heavy-duty conditions. Based on an average annual loader operation of 2,000 hours, it can last 3-5 years without replacement under normal maintenance.

 

275101789 Brake Disc Applications

 

For high-frequency loader operation in mining, infrastructure construction, ports, and other environments, the 275101789 brake disc demonstrates exceptional environmental adaptability.

In open-pit mines with temperatures exceeding 45°C, it can withstand heavy braking for 8 hours without performance degradation.

For dusty construction sites, the grooved structure and sealed mounting design effectively block impurities and prevent brake jams.

Suitable for frequent starts and stops in complex terrain, braking distance is shortened by over 15% compared to traditional cast iron brake discs, improving operational safety.
