GMN has been involved in the manufacture of special bearings for navigation systems, starting our company’s long tradition in measurement equipment.

PRECISION GUARANTEED

GMN bearings and bearing units for measurement equipment provide the highest precision and stable quality with low installation space and weight. Products include:

• Rotary encoder
• Navigation systems (e.g. gyro compass)
• Probes of coordinate measuring systems

The challenges for measurement technology:

• System accuracies up to
• Low, non-repeatable beat (NRR)
• High system rigidity
• High tuning accuracy
• Low starting and running friction torque
• Compact dimensions (thin-section bearing)
• Low system weight (materials, construction)
• Absolute cleanliness during assembly

OPTIMIZED ENGINEERING

Development and manufacturing products and solutions for measurement equipment places significant requirements on design, manufacturing, measurement systems and component handling. 100% inspection of individual parts and total systems are a significant condition for constant quality and the highest precision.

Significant performance criteria are:

• Very compact designs using GMN’s manufacturing technologies for thin-walled bearings
• Innovative, weight-saving compound techniques
• Assembly in laminar flow hoods
