Q355B Heavy-Duty Rear Hub Disc

Application

Heavy-Load Roller Equipment (Mining/Port)

Material

Q355B High-Strength Steel

Core Process

Rear-end closed structure reinforcement using Integral Blanking + Precision Forming. Leverages the superior yield strength of Q355B (≥355MPa) to create a "structural safety backstop," ensuring no deformation or cracking during full-load startup and emergency braking.

Precision Control

Strictly adheres to GB/T 1184-K Grade GD&T standards. Specialized inspection of hub disc Face Runout, ensuring flatness is controlled within 0.1mm/m.

Surface Treatment

Strict "Deburring" protocol using Double-Side Grinding. Sharp edges are chamfered/rounded to eliminate stress concentration. Surfaces are free of oxide scale and rust.

Material Adaptability

Source material strictly controlled per GB/T 1591. Designed specifically for heavy-load conveying environments in mining and ports.
