1. Functional use:
   PNW series microcomputer-controlled electro-hydraulic servo torsional fatigue testing machine is mainly used for torsional fatigue test and rotating gap,

static torsional stiffness and strength test of vehicle constant velocity drive shaft . The above test can be carried out on any shaft rod by replacing the attachment. There are 3000N.m, 5000N.m,

6000N.m, 10000N.m, 20000N.m and other specifications to choose from. Take 3600N.m as an example below. 2. Main technical specifications:
1. Maximum test torque: ±3600N.m, indication accuracy from 10%FS≤±FS
