Introduction
The Bearing Torsion Testing Machine is designed to evaluate the torsional performance of bearings and related mechanical components. The machine applies controlled torque to the test specimen and measures torque, torsion angle, speed, and other test data. It can be used for torque, peak torque, torsion angle, cycle, and failure testing, providing test curves and data for product development and quality control.
Application
The Bearing Torsion Testing Machine is suitable for:
(1) Bearing and bearing assembly torsion testing
(2) Automotive and mechanical components
(3) Shafts, pulleys and other transmission components
(4) Torque and torsion angle measurement
(5) Cycle, constant-torque and destructive testing
(6) Product development and quality inspection
Standards
(1) GB/T 2611 — General requirements for testing machines
The applicable testing standard can be configured according to the bearing type, test method, specimen structure, and customer requirements.
