1)Test bearing inner diameter: φ30~φ80mm;
2)Maximum load of the test bearing: axial load ±50kN, radial load 100kN, accuracy ±≤2% (below 10kN), axial loading radius: 200-400mm, maximum radial movable length 80mm;
3)Test maximum spindle speed: 2000r/min, accuracy ±≤2%;
4)Measurement and control system: Industrial computer automatically controls, monitors, prints and records experimental data;
5)Hydraulic system: the filtration accuracy of the hydraulic system is 5μm; it adopts a quantitative pump and water circulation system for cooling, and the oil temperature is not more than 65℃;
6)It can display various random test parameters, such as temperature, speed, current, load, vibration test value and control time. It has the function of random measurement display and printing of vibration, current and load curves. The measurement parameters and curve display can be switched between each other.
7)The testing machine has remote monitoring function, which can realize remote operation, monitoring and other functions. It can be controlled and tested manually and automatically. The software program can set the speed (r/min), load (N), and temperature (°C) parameters; it can also set the main engine current (A), load (N), temperature (°C), and vibration (dB) alarm parameters. When the temperature, load, vibration, current, or speed exceeds the alarm value, the computer will automatically shut down.
