Abstract: A race for a bearing, which is mountable to a mount, has an annular bearing surface with a center axis defining an axis of rotation for the bearing and mutually perpendicular radial and transverse directions relative thereto. The race also has a radial wall that is adapted for mounting the race to the mount in a manner such that a bearing transfer load is transferred between the mount and the race in the transverse direction and the race bearing surface maintains its substantially annular shape independently of a load applied to the mount causing distortion of the mount when the race is mounted to the mount and the mount is loaded.

Abstract: In a device for supporting arm driving shafts, articulating portions of adjacently provided first and second arms constituting a parallel link type robot are rotatably supported, via separately provided bearings, from supporting posts projecting from the robot structure, and the first arm and second arm are also coupled through another bearing.
