ACOUS NAVI for Vibration Diagnostic Devices diagnoses bearing damage (flaws, flaking) at an early stage with wireless vibration measurements and machine vibration analysis, and easy-to-use condition monitoring (CM) and visualization features.

Bearings are crucial components in all kinds of equipment, making condition monitoring a must for maximum reliability and minimal downtime. By finding and assessing changes at an early stage, users can take measures to keep equipment running smoothly.

Wireless vibration measurements and analysis are perfect for hard-to-access machinery, and diagnosis without disassembly helps prevent downtime and reduce the chance of unexpected failures.

Connect your smartphone or tablet to NSK's diagnostic device wirelessly (via Bluetooth®) to measure basic vibration values (OA) for machinery and equipment. We offer three evaluation modes to suit your needs: frequency analysis (FFT), time waveform analysis (WAVE), and bearing precision diagnosis.

The app includes ACOUS NAVI for Bearings: NSK’s specialized condition monitoring and bearing diagnosis software built on years of technology and expertise. In bearing precision diagnosis mode, ACOUS NAVI automatically detects if flaking or flaws are present, allowing for optimized predictive maintenance and replacement.

OA Mode:
Measure and see basic vibration parameters (acceleration, velocity, displacement). Allows for evaluations of vibration severity based on ISO 10816-3 or custom standards.

FFT Mode:
Visualize signals for vibration acceleration as a spectrum frequency-axis waveform.

WAVE Mode:
Visualize signals for vibration acceleration as a time-axis waveform.

Precision Bearing Diagnosis (ACOUS NAVI for Bearings)
Automatically diagnose flaws and flaking in bearings inside equipment based on the pulse generation frequency and actual rotation speed of the bearing.

Lookup values by simply entering the bearing designation, thanks to an extensive built-in database of pulse generation frequencies for over 5000 NSK rolling bearings.

ACOUS NAVI automatically performs complex processing including noise removal and frequency matching and offers three customizable bearing assessment thresholds.

Connect to Management Software: Vibro-Data Manager (Companion PC Application)
Manage data all in one place with Vibro-Data Manager on Windows PCs.
This software links with the app for centralized data management, trend graphs, and automatic CM reports for measurement data and diagnostic results.
