Twin Roller Tribometer 3000

TwinRoller-3000 is designed to study traction, wear, and rolling contact fatigue (RCF) under a 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 programmes and advance controllers allows for high repeatability and precision measurements.


Rtec Instruments

Rtec Instruments develops and manufactures advanced mechanical and surface testing and measurement solutions for research and industrial applications. They specialise in combining techniques that provide a unique perspective in material testing. Their testers include tribometer, profilometer, scratch tester, high-temperature indenter, and corrosion testers. Furthermore, their testers provide the most robust and versatile platform in the market for testing friction, wear, adhesion, hardness, roughness, and film thickness from nano to macro-scale.

Key Features

  • Pure rolling, pure sliding, combination of rolling sliding
  • Servo Controlled Load control
  • Environmental control
  • Versatile to mount several kinds of samples
  • In-line 3D optical inspection
  • In-line friction and wear

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.

Two Independently Controlled High Speed Rollers

Several In-line Sensors to Monitor Real Time Surface Interactions

  • A: Platform
  • B: Torque Sensors
  • C: Rollers
  • D: Motor
  • E: Force Sensors
  • F: Environmental Control

Many Configurations Are Possible

Rtec Instruments’ Twin Roller Tribometer comes in several application specific configurations.
