PI (Physik Instrumente) introduces the A-60x MTT, stainless steel multi-axis top that combines with its offerings of PIglide rotary air bearing stages and platforms. Air-bearings have no rolling or sliding elements and deliver completely frictionless, non-contact motion, resulting in negligible hysteresis or reversal error, better geometric performance, and velocity stability, which are ideal prerequisites for high-end industrial inspection and manufacturing operations.

Mounted to rotary air bearings to provide manual adjustments in X-Y-tip-tilt, the A-60x MTT enables the perfect alignment of a payload to the bearing’s axis of rotation. Constructed from durable, wear-resistant stainless-steel with table diameters from 75mm to 300mm and a clear aperture, this accessory is ideal for metrology, roundness measurement, and part gauging applications as passive rotary air bearings are designed for accuracy, precision, high stiffness, and ease of use, in any orientation, and are easily integrated with motors and encoders for complete positioning solutions.
