ABSTRACT:
A bearing assembly is disclosed in which a bearing having inner and outer races is seated in a manner which accommodates thermal expansion and contraction without allowing radial pressure to constrict the bearing. Two materials of differing coefficients of thermal expansion form the seat for the outer bearing race such that temperature variations cause the race to tilt around the ball of the bearing. The bearing assembly is particularly useful in rotary drive assemblies for antenna pedestals.
