The twin roller tribometer (TwinRoller-3000) is designed to study traction, wear and rolling contact fatigue (RCF) under various combinations of rolling and sliding. In-line sensors for measuring torque and acoustic emission allows quantification of minimal differences. With an open platform architecture that allows easy access, the tester comprises of two high torque independently controlled servo motors.

The force is applied using electro servo drives. Tests are performed under controlled environmental conditions, and run both dry and lubricated setups. The lubricant can be contained in a container or actively circulated during the test. Fully automated test programs and advance controllers allows for high repeatability and precision measurements.
