GMN Bearings for Rotary Torque Transducers

The rotational accuracy in torque transducers is everything and the key ingredient to exact performance is a super precision Angular Contact Bearing.

Why? Because this precision testing application comes down to microns. (Did you know that a micron is 1/50^th the width of a human hair?! This is actually finer than smoke!)

That’s why it’s impossible to leave the most critical component in your finely tuned instrument up to chance.

German-made GMN bearings are renowned for excellence—from the quality in our materials to the hand-checked inspection of every part that leaves our manufacturing facility in Nuremberg.

Advantages of Integrating GMN Bearings into Your Rotary Torque Transducer

• Accuracy
• Reliability
• Longevity

GMN, with our extensive expertise in designing components for high-speed and high precision applications like rotational torque transducers, presents precision angular contact bearings that go beyond the ordinary and elevate standards in reliability.

Our precision bearings are optimized to operate with minimal drag and power loss. Due to our P4+ precision rating, the bearing’s inner diameter, outer diameter and width tolerances are measured in values of microns. This characteristic not only contributes to the overall performance of the torque transducer but also enhances its ability to provide accurate torque measurements consistently.

Of the manufacturing tolerances, the runouts (or the running tolerances), are the most critical values for bearing performance. With torque transducers specifically, rotating coils act as transformers, to communicate data between the strain gauge and the stationary housing. The criticality of minimizing runout values is especially applicable in torque transducers as rotary transformers need to be precise as possible to minimize error and provide the most accurate readings possible. For this reason, all GMN P4+ angular contact bearings are manufactured with P2 runouts. That means that for the cost of a P4 bearing, GMN’s customers are receiving a P2 precision bearing.
