The answer is an out-of-this-world application solution! Every once in a while, an extremely unique application comes through the TriStar shop, and this Rulon J application was it!
This project involved choosing a durable slide-pad material for one of the world’s largest telescopes. But this telescope had an extreme location in an observatory 14,000 feet above sea level, atop a dormant volcano ― in Hawaii! Bearing requirements called for slide pads that could tolerate extreme altitude and atmospheric pressure. The material also had to deliver prolonged wear in temperatures ranging from -10° to +10°C with extreme UV exposure.
Here’s why low-friction Rulon J was selected over other bearing materials:
