Rolling Contact Fatigue Tester

• 

Rolling Contact Fatigue Tester is a specialized testing system designed to investigate traction, wear, and rolling contact fatigue under controlled rolling and sliding conditions. The tester evaluates material behavior under alternating surface stress fields that lead to crack initiation and material removal. Featuring an open-platform architecture, dual independently controlled high-torque servo motors, and servo-driven loading, the system delivers high repeatability and precise measurement for rolling contact fatigue studies in lubricant, automotive, railway, and aerospace applications.

Application

Rolling Contact Fatigue Research

Evaluation of rolling contact fatigue (RCF) under pure rolling, pure sliding, and combined rolling–sliding conditions.

Traction and Wear Analysis

Measurement of traction force and wear behavior at different rolling–sliding ratios.

Lubricant Performance Evaluation

Assessment of lubricant influence on rolling contact fatigue, wear evolution, and surface damage mechanisms.

Automotive and Rail Components

Testing of bearings, gears, wheels, and rails under realistic rolling contact conditions.

Aerospace and Turbine Components

Reliability assessment of rolling elements and transmission components subjected to cyclic contact stresses.
