• At the heart of the technology is a static bonded lower belt that meshes with the upper dynamic belt so that the active belting under tension is only a few inches long. Servo tuning can have much higher gains than conventional belts, because stiffness is high and does not change throughout the travel.

The ServoNut motor drive is a high force option for most of our motion chassis. ServoNut mates a high performance NEMA 23 motor set directly on a zero-backlash precision ball screw to enable high accelerations of heavy payloads. Learn More

The Super Z/Macro-Flexure system is a zero back-lash, zero friction linear bearing without rolling elements. It has all the advantages of an air-bearing in a previously unattainable package height, and none of the travel limitations of a typical flexure stage. Tip and tilt through its travel is limited to an amazing 1 arcsec over a travel of 10mm.

• Linear motion is derived by rolling shear members that are quite wide providing high resistance to shear and moment loads, even though they're very thin, 0.003 in., as an example.
• Primary features are its low profile nature, extreme low particle generation and inherent vacuum compatibility. No lubricants or maintenance are required, and it can be supplied with voice-coil, piezo-electric or screw type drives.
