ACOUS NAVI (FIELD SYSTEM)

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.


↓ Overview ↓ System Structure ↓ Solution Services

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
