Model 1620 Compressibility Machine


The Model 1620 Compressibility Test Machine provides a complete workstation to evaluate the compressibility of friction materials at ambient and elevated temperatures up to 600 °C. It is offered with either a pneumatic or hydraulic actuation system and conforms to U.S. and worldwide testing requirements. The hydraulic machine provides increased control accuracy and response. Both machines provide excellent precision and repeatability to measure deflection in microns, with consistent measurements over thousands of samples.


Load Control Modes Force, Brake System pressure or Pad Surface Area Pressure
Cylinder Stroke Length 40 mm / 100 mm
Load Capacities 60kN or 94 kN
Load Control Accuracy (High Load) ± 40 N (± 9.0 lb) (steady state)
Load Control Accuracy (Low Load) ± 20 N (± 4.5 lb) (steady state)
Low Preload Capability 100 N (60 kN machine) : 157 N (94 kN Machine)
