Fretting Tester FFT Series

Variety of Fretting Wear Testers for Nano, Micro and Macro Range Testing. Rtec Fretting Solution – The state-of-the-art fretting testers to provide unequalled specifications of stroke and frequency in the industry. Controlled stroke from 10 microns and frequency up to 300 Hz frequency makes it an ideal fretting wear tester for both industry and university research.


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

  • 10 µm to 2.8 mm Stroke
  • 1 to 300 Hz frequency
  • High frequency piezo Sensors
  • Electromagnetic Coils

A Fretting Machine Like No Other

Test the surface damage that occurs between two contacting surfaces. Analyse two-body abrasion, adhesion, and/or fretting fatigue wear.

  • A: Down Force Control - Real time down force control to account for contact wear
  • B: Voice Coil - Electromagnetic actuator that imparts linear reciprocating motion. Dependent on the test additional coils can be installed on the tester to double the force range
  • C: High Accuracy Position Control - The most accurate and precise displacement control in the market. Up to 1nm resolution and micron level of accuracy. Extremely low noise. High responsiveness for dynamic performance of system
  • D: Environmental Control - Study fretting wear across a wide range of temperature
  • E: Unmatched Waveform Control - Without the friction of rolling or bearing, the magnetic flexure based design provides the control required for the most sensitive of tests. The unique controller adjusts to friction changes to maintain the stroke control in real-time
  • F: Friction Measurement - The tester comes with high frequency piezo sensors to measure real-time friction. Ultra low noise amplifiers aids in detection of minute changes in friction with ease
  • G: Additional In-line Sensors - Sensors such as acoustic emission to detect onset of cracks, and ECR to measure surface resistance changes to gain more insight on the material interface.
  • H: Liquid Containers, Sample Holder - Customizable liquid and sample holders for standard and non standard tests.

Choose your fretting tester model

All Rtec Fretting testers are constructed on flexure based designs. The motion is imparted using electromagnetic actuators with real time stroke and wave form correction controllers. The difference in model lies in the power the coil can impart during the test.
