The Fretting Tester is built for high-precision testing of friction and wear of lubricants and materials.
The Electromagnetic actuator produces sinosodial motion of up to 500 Hz from 5 µm to 5 mm.
Ultra high data acquisition
Closed loop down force control
Perform multiple ISO, ASTM, DIN tests
Piezo sensors to measure friction even at 500 Hz oscillation speeds
5 µm to 5 mm
Ultra high precision control
Real Time Stroke Control
LVDT sensors to monitor and rectify stroke on each oscillation
Unmatched Waveform Control
The flexure-based design, without the friction of bearings, provides the control needed for the most sensitive of tests.
The exceptional flexure suspension guides the magnet assembly without lubrication or contact. The magnet, coil, and stators are built to eliminate performance degradation over time and provide close to maintenance-free operation.
Temperature, high pressure, vacuum, humidity, and Tribo corrosion chambers
Various Sizes to Meet Application Requirement
The tester’s design allows a broad range of forces and displacements
- Maximum forces ranging from 10 N up to 3 kN
With its efficient bearing free design, the fretting tester is engineered to be used in different controlled environmental chambers—temperature (up to 1000 °C) and humidity (5 to 95% RH)
Sensors such as acoustic emission to spot start of cracks and ECR to measure surface resistance change shed more light on the test interface
High-Accuracy Position Sensor and Control
The most precise and accurate displacement sensor control available commercially
- Up to 1 nm resolution and micron level of accuracy
- Very low noise
