ABSTRACT:
A linear motion ball bearing having a ball bearing portion provided with an outer sleeve, a ball retainer fitted in the outer sleeve, ball bearings retained in a circulating passage formed in the ball retainer, and a flange portion for fixing the ball bearing portion to a machine or an apparatus. The ball bearing portion has an annular collar having a spherical outer surface around an end section thereof, and the flange portion has a hollow space defined by a spherical inner surface concentric with the collar. The ball bearing portion is adapted to swivel with respect to the flange portion so that an angle of inclination of a shaft, which is held in the ball bearing portion, with respect to, for example, a plane at which the flange portion is fixed to a machine or an apparatus can be arbitrarily set, thereby enabling the linear motion ball bearing to be fixed to a machine or an apparatus simply, easily and accurately.
