This device features built-in simple vibration diagnostics for monitoring equipment characteristics and general changes and automatic precision diagnostics for bearing flaws and flaking.
You can check the state of vibration and monitor changes in equipment.
<Built-in precision bearing diagnostics: ACOUS NAVI for Bearings>
Automatically diagnose bearing flaking and flaws by simply entering the designation and rotational speed of the target bearing.
Lookup entries from a database of over 5000 NSK standard bearings—no complicated calculations or settings required.
* Supports diagnosis of non-NSK bearings through input of the bearing's "pulse generation frequency" as published by the manufacturer.
Customize three sensitivity levels for diagnosis to match the degree of damage that causes problems for a particular machine.
Conditions for vibration measurements (OA), frequency analysis (FFT), time domain waveforms (WAVE), and precision bearing diagnosis can be set as desired for individual machines.
NSK's vibration diagnostic device is perfect for regular patrol inspections. In this mode, the device automatically measures vibration (OA), analyzes frequency (FFT), makes a time-domain waveform (WAVE), performs precision bearing diagnosis, and saves all data for future use. In the automatic measurement mode, you only need to set the storage destination and bearing diagnostic conditions before measurement. It only takes about 30 seconds after the start of measurement to obtain vibration analysis and bearing diagnosis results.
Assessments can be performed at three sensitivity levels: High, Medium, and Low.
※Image for illustration purposes only. Actual may vary.
Easily re-diagnose saved vibration data after changing conditions like bearing designation and rotation speed—no new measurements needed.
Example) Diagnosis of bearing with flaw on the inner ring raceway surface
Bearing designation: 7000A, Inner ring rotation: 1000 min-1
(Wrong bearing designation and rotation speed)
Bearing designation: 6002
Inner ring rotation: 1300min-1
(Corrected bearing designation and rotation speed)
Bearing designation: 7000A
Inner ring rotation: 1000 min-1
Saved data can be organized by facility, machine, and part, and trends in vibration values can be managed in chronological order.
Check saved data and select report data for output (Excel format).
You can set the patrol route on PC and send the data to the app to show measurement points in the specified order and save results.
