Truck Steering Parts 1041QS-3001030B Steering Knuckle Pin

• Medium-Duty Logistics Trucks: Primary steering pivot module for regional delivery trucks and commercial box transport vehicles.
• Urban Vocational Fleets: Infrastructure support for short-haul utility vehicles, public service trucks, and refuse collectors undergoing constant turning cycles.
• Intercity Commercial Buses: Wheel-end steering axle pivot core for passenger buses demanding smooth, predictable handling characteristics.

• Carburized Dual-Zone Metallurgy: The 20CrMnTi alloy achieves an outer shell hardness of HRC 58-63 to resist abrasive needle bearing wear, while its tempered core remains ductile to absorb intense pothole impacts without snapping.
• Ultra-Precise Centerless Grinding: Final sizing via CNC centerless grinders guarantees a precise h5/h6 cylindrical tolerance, ensuring uniform load distribution across the steering knuckle bushings to eliminate localized hot spots.
• Polished Low-Roughness Finish: A surface roughness index below Ra 0.40 μm minimizes friction coefficients, drastically lowering steering wheel resistance and extending the lifespan of the entire wheel-end assembly.
• CNC-Milled Draw-Key Geometry: The lock bolt notch is machined to exact positional tolerances, ensuring a rigid metal-to-metal interference fit inside the axle beam eye to completely prevent structural pin rotation.
