Abstract:
A non-metallic high temperature ball bearing assembly comprising:a plurality of spherical ball bearings of uniform radius, the ball bearing being completely formed of a ceramic material;an outer race formed completely from a ceramic material and having a ball receiving groove formed therein, said groove being arcuate and having a radius greater than the radius of the ball bearings such that each ball bearing contacts the outer race at no more than two points, with the two points being positioned such that a plane intersecting the two points is parallel with an axis of the bearing assembly; andan inner race formed completely from a ceramic material and having a ball receiving groove formed therein, said groove being arcuate and having a radius greater than the radius of the ball bearings such that each ball bearing contacts the inner race at no more than two points, with the two points being positioned such that a plane intersecting the two points is parallel with an axis of the bearing assembly.
