Precision Motor/Screw Drives with Mechanical Bearings
PI‘s range of traditional precision motorized stages covers travel ranges from 5mm to 1000mm.  Stages with servo and stepper motors guided by ball bearings and cross roller bearings for higher precision are offered. 

High Precision Linear Motor / Torque Motor Direct Drives with Mechanical Bearings
For higher precision requirements and fast precision automation applications, frictionless 3-phase direct-drive linear and torque rotary motors are used.  Integrated optical scale encoders provide sub-nanometer resolution.  Linear motors are non-contact and can provide extreme lifetime with fast acceleration and high velocities.

Ultra-High Precision Stage Applications: Air Bearing Stages
Air bearing stages with linear motors are completely free of friction and wear. They provide the highest performance with extremely good repeatability, straightness, and flatness. These frictionless positioners are used in metrology and positioning applications with the highest demands on lifetime and accuracy.

6-Axis Parallel Kinematics Stages (Hexapods)
As the world leader in parallel kinematics six-axis hexapod precision positioning systems, our engineers can find the appropriate technology for almost any complex motion and positioning application for industrial, OEM, and scientific applications.

Engineered Motion Sub-Systems 
Multi-axis positioning systems with controller and software

Piezo Motor Drives
In addition to traditional electromagnetic motors, PI also offers a number of piezo motor drive systems for special applications.   Piezo motors are intrinsically self-clamping, non-magnetic, very compact, and provide nanometer resolution along with very fast response.

Vacuum Environments
Our new line of motorized linear stages with ball bearings and crossed roller bearings is also available for vacuum and UHV environments and can be customized for beam line integration.
