Torsion performance testing instrument for automobile pulley, steering column and other components

 The torsional fatigue testing machine for automobile parts such as drive shaft steering column tensioner pulley is mainly used for torsion test of automobile transmission shaft, automobile bearing, steering column, steering knuckle and other parts and various materials such as metal and non-metal, and performs static or dynamic torsion.
Fatigue durability test can realize the measurement and control of torque and torsion angle
.

It can also be equipped with high temperature furnace, low temperature box, corrosion box and other environmental boxes to complete the mechanical test of materials in different environments
.

Widely used in auto parts, rail vehicles, aerospace, ships and other fields
.
