Technical Specifications
The PT400 Mini is suitable for applications in educational institutions and research facilities, providing a hands-on tool for studying vibration analysis and mechanical fault diagnostics.
This loading mechanism is mounted at the end of the shaft and applies controlled radial and axial loads. It uses two inner ring supports (50 mm, NSKHR32011XJ) with single-row tapered roller bearings, suitable for test bearings with inner diameters ranging from 20 mm to 45 mm. The loading system applies force to the test bearing via a servo-controlled actuator, and load cells are used to precisely measure the applied bearing loads.
The system is designed for easy installation and removal of test bearings and effectively transfers applied loads directly to the bearing under test. By adjusting the servo electric actuator, vertical loading can be varied from 50 kg up to 1500 kg. The system enables both radial and axial loading, and the signal output from the load cell reflects the proportional load applied, with results displayed clearly.
The PT500Mini is a compact mechanical fault simulation platform driven by an ABB three-phase asynchronous motor via a direct coupling, with speed controlled by a frequency converter. It incorporates an adjustable magnetic powder brake to apply precise test loads.
Engineers can introduce various bearing fault types and assess their frequency characteristics at different speeds. The system also supports gear fault analysis, blade integrity testing, rotor balancing, and shaft friction evaluation, either independently or in combination, within a controlled and safe test environment.
Designed for both educational and research applications, the PT500Mini provides a flexible and realistic platform for studying fault behaviour in rotating machinery.
