Truck Brake Drum Volvo Supplier Factory

Truck Brake Drum Volvo

Volvo heavy‑duty trucks demand brake drums that conform to precise OEM specifications and deliver consistent performance in regional and long‑haul applications. The Truck Brake Drum Volvo offerings from Xingtai SNT Auto Parts Factory are engineered to match these exacting standards, combining material quality with exacting manufacturing processes.

OEM‑Level Design Replication

Using detailed Volvo engineering drawings and 3D scans, our design team recreates the exact bolt‑pattern, bore dimensions, and cooling‑fin profiles specified for Volvo axles. This ensures a drop‑in fit and maintains the original braking geometry critical for consistent pedal feel and stopping distance.

Controlled Casting and Material Integrity

Drum blanks are cast from grey iron alloys chosen for stable graphite content and thermal fatigue resistance. Our low‑porosity casting methods and controlled mold temperatures produce uniform wall thickness and minimal defects. Internal cooling‑fin arrangements mirror the Volvo design, promoting heat transfer and preventing thermal warping.

Advanced Machining Workflow

Each drum undergoes:

• Rough turning to remove excess metal.

• CNC precision turning to achieve bore concentricity within ±0.02 mm and flange flatness within ±0.03 mm.

• Fine grinding of the braking surface to specified roughness for optimal lining contact.

Quality measurement tools—laser trackers and CMMs—verify dimensional integrity before proceeding to final inspection.

Comprehensive Testing Regimen

We subject drums to:

1. Dynamic balancing to eliminate vibration.

2. Non‑destructive inspection (magnetic particle) to detect surface cracks.

3. Hardness testing to confirm compliance with Volvo’s Rockwell specifications.

4. Thermal endurance trials on sample drums, simulating repeated high‑load braking cycles.

Passing drums receive traceable batch identifiers and are ready for shipment with full test reports.

Technical Support and Maintenance Guidance

Our Volvo‑compatible brake drums come with detailed installation instructions, including run‑out measurement procedures and torque sequences. Maintenance guidelines specify resurfacing limits, inspection intervals, and best practices for lining selection. Through reliable manufacturing and dedicated support, Xingtai SNT Auto Parts Factory meets the demands of fleet operators using Volvo trucks worldwide.
