Heavy-Duty Conveyor Rear Hub Disk (Q355B Structural Steel Component)
Application – Mining & Port Bulk Material Handling Systems
Engineered for heavy-duty conveyor drum assemblies, this rear hub disk functions as a critical load-bearing safety component in high-stress environments such as mining operations, port logistics, and bulk material transportation systems.
Structural Engineering – High-Load Reinforced Design
Manufactured using integrated blanking and precision forming processes, the component is designed as a closed reinforcement structure for conveyor drums.
Optimized for extreme operating conditions:
- Withstands full-load start-up torque
- Resistant to emergency braking impact loads
- Eliminates risk of deformation and fatigue cracking under cyclic stress
Engineering Advantage:
Transforms Q355B steel strength into stable long-term structural reliability.
Precision Control for Rotational Stability
- Complies with GB/T 1184-K geometric tolerance standards
- End-face runout and flatness controlled within 0.1 mm/m
- Dedicated inspection for rotational symmetry and face alignment
Ensures stable operation in high-speed conveyor drum systems.
Surface Engineering – Stress Reduction Treatment
- Double-side mechanical grinding for full-edge deburring
- Edge radiusing to eliminate stress concentration points
