Precision Engineering

When a customer comes to Professional Instruments Company with an air bearing application, we try to provide a solution from our standard line of spindles. Occasionally a customer will have a set of specifications far enough outside of our standard lines that we must design and build a spindle specific to their application. Our engineering and manufacturing staff combines years of experience with a genuine enthusiasm for problem solving. The range of custom air bearing spindles produced at Professional Instruments Company over the last 35 years is mind boggling. Hemispherical bearings, dual diameter bearings, custom BLOCK-HEAD spindles, air pad spindles, and even spindles that operate in vacuum have been built. The long history of Professional Instruments Company includes custom spindle making almost all the way back to the beginning in 1946.
