Bearings, anti-creep devices and the medical industry
Few 1950’s companies foresaw the path they must take to thrive in 21st Century markets. A case in point is the change in the surgical equipment market. Robots are invading it. Maybe this was anticipated in science fiction but in the real world, who was inspired to anticipate such an evolution? Motion control is essential […]

Anti-cage creep mechanism helps bring Lasik surgery equipment into focus
Motion control is essential for the digitization and automation of equipment, and bearings are at the core of frictionless movement. In 1956, just distributing bearings in California was viable, even on a small scale. For many small distributors, with growing globalization through the end of the 20th century, it was change or die. This is…
