Next generation Rtec SRV test system measures the coefficient of friction and wear between a lubricant, oil, grease etc and two specimens in a loaded contact in linear oscillatory motion from 5 micron strokes. RTEC offers state of the art SRV machine is based on one of our two platforms MFT-5000 or FFT-5000 (mentioned in sections below). The sliding reciprocating friction module has a wide load, speed and temperature range. Using various combinations of test conditions, it can test friction and wear data using several ASTM, DIN, ISO standards on same tester.
● 5 micron to 4mm Stroke, Upto 300Hz
● Piezo Sensors
● Electromagnetic Coils
● -40 to 250 (optional 500C) Temperature

All Rtec SRV modules are constructed on flexure based designs. The motion is imparted using electromagnetic actuators with real time stroke and wave form correction controllers.
Force sensors- The tester uses high resolution, fast frequency response piezo sensors to measure real time inline friction forces.
Reliabilty on long runs - The unique flexure suspension guides the magnet assembly without contact or lubrication. The magnet, coil and stators are designed to eliminate performance degradation over time and deliver near maintenance-free operation.
Position Sensor and Control - The most accurate and precise displacement sensor control on the market • Up to 1nm resolution and micron level of accuracy • Extremely low noise
Platform Rigidity - Vibration dampening frame, symmetrical design, rigid samples holders etc. allows for high system stiffness. High rigidity allows to create fretting loops with ease.
Environmental Chambers - Wide temperature from -40 to 1200C range allows the fretting tester to simulate several real life scenarios easily. The temperature and test duration is the test system is controlled using computer.
Inline Sensors - Sensors such as Acoustic emission to detect onset of cracks, ECR to measure surface resistance change allows to gain more insight on the test interface
Rtec 3D Profiler created 3D mark of ball scar surface after the test. The profiler is able to measure volume wear of ball.
