ABSTRACT:
An improved linear ball bearing is disclosed which essentially comprises a bearing casing and a pair of retainer and side cover assemblies. The last mentioned assembly consists of a retainer half and a side cover and the two members are integrally secured to one another. On the inner end face of the side cover are formed U-shaped ball movement direction reversing grooves which are located corresponding to loading ball guiding grooves and non-loading ball guiding holes. The retainer half contains horizontal member, inclined members and lower holding members each of which is protruded from the inner end face of the side cover toward those of the opposite side cover. Between the adjacent concave end faces of these members are formed loading ball guides of which inner diameter is substantially same to the outer diameter of rolling balls and which are arranged so as not to cause any falling-down of the balls therefrom. The members of the respective retainer halves are dimensioned exactly to one half of the length of the bearing casing. One of the inclined members and lower holding members has engagement pins at the end thereof, while the other one has engagement holes at the end face thereof to receive the corresponding engagement pins.
