Professional Instruments Company HomeProductsPostersApplicationsOur Company Submit a Request Gravity Research 1968 Among the first customers for the BLOCK-HEAD® air bearing spindle was the University of Virginia where Dr. Jesse Beams and others used its friction-free rotation to seek a more precise value for the force of gravity. More recently, we built an all aluminum model 10R BLOCK-HEAD® bearing for the University of Washington, where researchers hope to define “G” to several more decimal places and, perhaps, find evidence of the theorized “fifth force”. These scientists worship at the shrine of symmetry; it is crucial that any lumps they see are in the external world, not in the spindle.
