Add value to your metrology system with Quadrant
The Quadrant rotary table range is the world's leading range of metrology grade rotary tables. With extremely high precision and durability, it is designed to seamlessly integrate with a multitude of metrology systems, including CMMs, tactile measurement systems and scanning systems, enabling more measurement capability and capacity.
Quadrant is based on over 70 years of continual development and innovation from Rotary Precision Instruments, the leader in precision positioning systems for metrology use. For accuracy and reliability, no other system can match it.
The Benefits of Quadrant
Unbeatable precision
Quadrant rotary tables have exceptionally high accuracy levels, offering angular positioning accuracy as low as 1 arcsecond (0.0003deg) and repeatability as low as +/-0.2arcseconds (0.00006deg).
Because the accuracy and repeatability of Quadrant is so good, it has virtually no contribution to your measurement uncertainty budget.
Legendary robustness
The Quadrant range is built on decades of expertise in rotary excellence. Like all of our rotary products, Quadrant is designed to be used in harsh environments without losing accuracy or performance, making it perfect for shop floor use.
This allows the system to perform just as intended, every time, ensuring customer satisfaction and reduced support overhead.
Flexible range of options
The Quadrant range offers a multitude of options to suit every need. From small systems up to systems that support loads in excess of 10,000lbs, we've got every scenario covered.
With zero and near-zero backlash drives available, scanning systems can work seamlessly and accurately.
Not sure what the most suitable option is? We're always happy to talk through options with you, including design of bespoke systems to your needs.

Unquestionable Heritage
With over 70 years' of innovation in developing and manufacturing rotary products, no company in the world has the experience of RPI.
We've been developing systems to be used and installed on CMMs since the early 1970s, so nearly 50 years' experience of metrology integration comes as standard.
Easy integration
The Quadrant range is designed for you to be able to easily access, integrate, and control. You can use your own control system to directly interact with the unit, or you can select the optional QuadMotion control module.
The choice is yours, meaning you can customize your system design exactly to requirements.
