USD has developed a long life version of its spinning mass rate and rate-integrating gyroscopes. Under development and testing for over ten years, USD has succeeded in extending the life of it's gyros from a typical 4,000 hours to a minimum of 12,000 hours.

The long life components can be added to any of our rate and rate-integrating gyroscopes which include all of the form, fit, function, drop-in replacements for the Honeywell GG1111 and the Atlantic Inertial Systems GIG6, GIG5/GRG5 gyros.

Since spin motor bearing failure is the predominant cause of gyro failure, at the heart of this design is a special bearing that utilizes state-of-the-art materials and advanced lubrication. The completed motor assembly is run-in for a minimum of 96 hours to fully channel the lubricants. During this period, all motor performance parameters are monitored including starting/running currents and noise levels.

• - For applications that require continual operation of gyroscopes.
• - Increases operating life from 4,000 hours to a minimum of 12,000 hours.
• - State of the art bearing materials, construction and lubrication.
• - Ball material has a lower coefficient of friction yielding in less noise and vibration.
• - Reduced starting and running torques.
• - Decreased lubrication degradation.

USD's long life gyro design has been laboratory and field tested under severe environmental conditions ranging in life from 16,000 to 22,000 hours.
