Twin Roller Tribometer 3000

TwinRoller-3000 is designed to study traction, wear, and rolling contact fatigue (RCF) under wide range of test conditions. In-line torque, acoustic etc.  allows quantification of minute differences. Rtec-Instruments’ TwinRoller-3000 is an ideal twin roller machine to study traction, wear, and rolling contact fatigue under various combinations of rolling sliding ratios. With an open platform architecture that allows easy access and use, the tester comprises of two high torque independently controlled servo motors. The force is applied using electro servo drives.  Fully automated programs and advance controllers allows for high repeatability and precision measurements.

Why Dual Roller Tribometer?

Rolling-contact fatigue (RCF) is defined as a failure or material removal caused by the surface alternating stress field. The failures are typically driven by crack propagation. The extent of failure or the  mechanism depends on a number of factors. For example, lubricant cleanliness, material quality, and roughness. With advent of high speed trains, EV vehicles, and turbines, rolling contact fatigue testing has become very important to prevent the failure of components.
