Volvo Brake Drums China Factory

Volvo brake drums

play a critical role in ensuring safe, controlled stopping for heavy‑duty vehicles. At Xingtai SNT Auto Parts Factory, we focus on producing brake drums that meet the precise requirements laid out by Volvo’s engineering teams, delivering components that integrate smoothly into existing systems without the need for modification or adjustment.

Design and Material
Each brake drum is manufactured from high‑grade gray cast iron, selected for its balance of strength, thermal conductivity and wear resistance. The design takes into account the specific wheel‑hub dimensions used on Volvo models, with exacting tolerances to ensure proper fit and run‑out values. This alignment is crucial to prevent uneven lining wear and to maintain consistent braking torque under varying loads and speeds.

Manufacturing Process
Our production line begins with a thorough inspection of raw materials, followed by a controlled casting process. Once the iron solidifies, each blank undergoes stress‑relief heat treatment to stabilize the microstructure. CNC machining then brings the drum to final dimensions: the inner surface is turned to achieve a smooth finish, while the mounting face is milled to ensure precise concentricity. Finally, all drums are shot‑blasted to remove any surface irregularities and are coated with a rust‑inhibiting primer.

Quality Assurance
At Xingtai SNT Auto Parts Factory, every drum is subjected to a series of checks before leaving the plant. Dimensional inspections verify adherence to Volvo’s published specifications for diameter, width and flange thickness. A dynamic run‑out test confirms that the drum will not wobble during rotation, minimizing vibration and noise in service. We also perform hardness tests to guarantee that the braking surface withstands repeated thermal cycles without cracking or glazing.

Application and Compatibility
These brake drums are designed to match the original Volvo parts in form, fit and function, fitting models such as the Volvo FH, FM and FMX series without alteration. They accept standard lining kits and sealing assemblies, allowing fleet operators to use existing maintenance procedures and spare‑parts inventories. Whether installed on a single axle or in multi‑axle configurations, our drums deliver consistent performance over extended service intervals.

Conclusion
By combining precise engineering, rigorous testing and careful material selection, Xingtai SNT Auto Parts Factory provides Volvo brake drums that maintain braking reliability and contribute to vehicle uptime. Our commitment to process control and dimensional accuracy helps ensure that each component performs as intended, supporting the safety and efficiency expectations of Volvo fleets worldwide.
