PI (Physik Instrumente) offers the industry's most comprehensive portfolio of precision motion technologies, spanning a wide range of applications and performance requirements. PI USA operates in full compliance with U.S. export control regulations governing the handling and distribution of controlled technologies.
PI is a privately held company specializing in the design and manufacture of high-performance precision motion and automation systems—including air bearing stages, precision gantries, parallel-kinematic hexapods, piezoelectric nanopositioning systems and piezo motors—at facilities across North America, Europe, and Asia. Founded over 50 years ago, the company currently employs more than 1,900 professionals worldwide.
In November 2025, PI transitioned from its long-standing facility in Auburn, MA, to a newly constructed manufacturing and engineering center in Shrewsbury, MA. This new U.S. headquarters consolidates operations previously distributed across Auburn and Hopkinton, MA. At approximately 140,000 square feet, the Shrewsbury facility more than triples the combined footprint of PI’s former sites in Auburn, Hopkinton, and Nashua, NH, supporting expanded production capacity, R&D, and customer service functions.
Our customers include leading technology companies and research institutions operating at the forefront of photonics, life sciences, semiconductor manufacturing, and aerospace. PI’s precision motion solutions have played a critical role in enabling numerous breakthrough innovations and scientific advancements across these fields.
PI (Physik Instrumente) LP, the U.S. subsidiary of the PI Group, operates several facilities across North America. Its corporate headquarters is located in Shrewsbury, MA, with an additional engineering, and manufacturing operation in Nashua, NH.

PI USA Design & Manufacturing: Leveraging Decades of Expertise in Precision Industrial Automation for Continuous 24/7 Operation
Over the past several decades, PI USA has made substantial investments in the design and manufacture of ultra-high-precision air bearing systems, piezo nanopositioning solutions, and direct-drive mechanical bearing stages. To support continued growth, the company relocated to a new ~140,000 sq-ft facility in Shrewsbury, MA, in fall 2025—approximately a decade after expanding its engineering and production operations at its Hopkinton, MA site. Around that time, PI USA also finalized the acquisition of Nelson Air Corp (Nashua, NH), a specialized manufacturer of air bearings and air bearing motion platforms.
PI’s manufacturing operations employ advanced Haas CNC machining centers and high-precision Okamoto surface grinders to produce industry-leading motion systems. The engineering team has developed and delivered hundreds of air bearing solutions for industrial automation in sectors such as semiconductor metrology, flat panel inspection, and data storage.
The acquisition of Nelson Air in 2014 has strengthened PI’s position with over 30 years of expertise in air bearing design, controls, and vertically integrated manufacturing. PI’s acquisition of ACS Motion Control in 2017 further expanded its capability to deliver fully integrated, world-class precision motion and automation platforms.
PI’s in-house engineered systems and components have enabled customers around the world to increase their productivity and technological advantage for 5 decades. A sample of collaborative work with our customers can be see in the videos below. With a large basis of standard precision motion products and proven methodologies, PI is in the position to quickly modify existing designs or provide a fully customized OEM solution to fit the exact requirements of your application from the whole motion range from finger-tip sized nano-positioners to large scale stages with long travel ranges, through a plethora of different drives and guiding systems.
PI's Nanopositioning products are world-known for their precision. To continuously improve our products and to verify the performance, we have designed world-class nanometrology labs, with six-fold-isolation, on a separated foundation in the basement of the factory.
Sub-nanometer resolution measurements not only require highest precision measuring equipment (we use world-class laser interferometers and capacitive sensors), but also an environment with extremely high temperature stability and total absence of vibration. The acoustic sound waves of a conversation alone can excite vibration in the range of several 10 nanometers. Vault-like doors keep noise out of our nanometrology labs.
