ACOUS NAVI condition monitoring/diagnostics for FANUC Corporation’s FIELD system * 1 open manufacturing platform.

* 1 FIELD system is a registered trademark of FANUC Corporation.


This product has been discontinued as of December 2022.

Keeping equipment running at peak performance starts with bearings, ball screws, and linear guides. ACOUS NAVI offers condition monitoring and diagnostics of these critical components to support predictive maintenance1. By catching signs of damage or deterioration at an early stage, you can avoid costly and unexpected downtime.

* 1 Maintenance work guided by failure predictions based on the monitoring of decreasing function in individual machines and deterioration patterns.


Ball Screws

Linear Guides

Damage and deterioration in machine elements gradually progresses as machine runtime increases, leading to equipment failures and abnormalities.
Catching these problems early is especially effective for predictive maintenance.

Progression of Equipment Damage/Deterioration

ACOUS NAVI catches the signs of damage when they start—the ideal time for predictive maintenance. NSK’s unique vibration diagnosis technology builds on years of R&D on the mechanisms behind damage and deterioration in bearings, ball screws, and linear guides.

Predictive Maintenance Processes

Predictive maintenance comprises several processes including visualizing conditions, monitoring/diagnostics, and investigating causes/enacting countermeasures.

ACOUS NAVI is a comprehensive solution for detecting, visualizing, and diagnosing problems at the right time.

NSK has spent years cultivating knowledge on the mechanisms behind damage and deterioration in bearings, ball screws, and linear guides. Now, we put expertise into practice with ACOUS NAVI condition monitoring/diagnostic software.

The entire ACOUS NAVI line supports predictive maintenance of equipment and machinery through diagnosis at the early signs of damage.
