Alloy Wheel Rotary Bending Fatigue Testing Machine

Rotating-bending fatigue rig that applies a cyclic moment to car and two-wheeler alloy wheels until crack or set life. Used by wheel foundries and OEM validation labs.

Specification

The wheel is clamped on its mounting face while a loaded arm rotates, imposing a fully reversed bending moment on the rim and disc. Cycle count and deflection are monitored, and the machine stops automatically when stiffness falls by a set percentage or a crack grows.

Features

• Fixed rotating loading arm with adjustable moment
• Wheel mounting plate with bolt circle adapters
• Cycle counter with automatic stop on deflection drop
• Variable speed drive from 500 to 1500 rpm
• Heavy frame with vibration isolation feet
