Angular contact

PoGOLite, the Polarized, Gamma-ray Observer, which will be re-launched later this year to study high energy light (x-rays) emitted by heavenly bodies incorporates Kaydon thin section bearings in its altitude control system.

Supplied by R. A. Rodriguez, the 50 and 70mm Kaydon angular contact bearings allow accurate control of the elevation angle of the tele scope. The elevation bearings carry the full mass of the 700kg telescope and are able to survive the 10g shock resulting from the launch of the parachute during landing. In addition, 90 and 180mm Kaydon angular contact bearings have also been specified for the critical azimuthal motion of the gondola.
