BPW Brake Drum 03272048780 Supplier

BPW Brake Drum 03272048780

The BPW Brake Drum 03272048780 model is identified for a specific axle configuration commonly associated with trailer systems. While the designation refers to a recognized pattern, Xingtai SNT Auto Parts Factory produces this brake drum based on the provided dimensional and performance specifications. The focus remains on precision, consistency, and thorough validation processes to ensure compatibility and safe braking behavior.

Model-Specific Requirements

Brake drum 03272048780 must conform to exact dimensions:

• Bolt circle diameter and stud hole pattern: Matching the corresponding axle hub assembly to enable correct mounting.

• Inner bore diameter: Ensuring proper fit with hub splines or pilot surfaces.

• Drum depth and flange thickness: Providing sufficient material for heat absorption and structural strength while allowing room for brake shoe engagement.

• Cooling-fin design: If specified, facilitating airflow to dissipate braking heat according to the expected load profile.

Xingtai SNT Auto Parts Factory’s engineering team works from detailed drawings or measurement data to replicate these dimensions accurately.

Material and Casting Approach

Key steps include:

1. Selection of cast iron alloy: Composition aligned with fatigue resistance and thermal conductivity requirements.

2. Controlled melting procedures: To maintain consistent chemical makeup, minimizing batch-to-batch variation.

3. Sand mold preparation: Using CAD-derived patterns to shape the drum cavity precisely, including internal cooling-fin configurations.

4. Casting under monitored conditions: Regulating pouring temperature and cooling rate to reduce porosity and internal stress formation.

Machining and Dimensional Control

After casting:

• Rough machining: Removes excess material and shapes the inner bore and mounting flange roughly to size.

• CNC finish machining: Refines critical surfaces with tolerances often within ±0.05 mm for bore concentricity and flange flatness.

• Surface grinding: Achieves the braking surface finish necessary for predictable friction, aiding bedding-in of linings.

• Laser inspection: Conducted post-machining to verify that all dimensions conform precisely to the 03272048780 specification.

Quality Verification and Testing

To ensure safety and performance:

• Non-destructive testing: Magnetic particle or ultrasonic inspection to detect cracks or inclusions that might compromise integrity.

• Dynamic balancing: Checking and correcting mass distribution to minimize vibration during rotation.

• Hardness testing: Verifying material properties after any heat treatment or stress-relief processes.

• Thermal endurance checks: Sample drums may undergo simulated braking cycles to confirm they resist distortion under repeated heating.

Each drum passing these checks is recorded with a batch identifier linking to inspection records.

Installation Guidance and Maintenance

For operators fitting drum 03272048780:

• Installation instructions: Including recommended torque sequences, run-out measurement procedures, and alignment checks to avoid uneven wear.

• Inspection intervals: Advising frequency of visual checks for cracks, measurements of run-out, and thickness measurements to determine when resurfacing or replacement is needed.

• Resurfacing limits: Clear specifications for minimum allowable diameter after machining to maintain safety margins.

• Compatibility notes: Confirming that linings and hardware used with this drum match intended dimensions and performance requirements.
