For the lack of the right bearing, the kingdom of ever-faster microprocessors might have been lost. But this story has a happy ending.
Technical achievements in microprocessor manufacturing, diagnostic equipment and automation have demanded increasingly more precise motion control. Whether it’s wafer positioning for the efficient manufacture of ICs, pick and place, vision inspection, parts transfer, a microscope stage under computer control or precise vertical movements, linear bearings have had to evolve rapidly in order to carry heavier loads, take up less space and be reliably precise.
