ABSTRACT:
In a longitudinally movable rolling bearing having a plurality of endless rows of spherical rolling elements, elongated races are provided for supporting loaded rolling elements against the inner boring of a housing. The radially directed surfaces of the rails are identical, so that the rails may be reversed to prolong the life of the bearing. In one embodiment, the rails are straight in the lengthwise direction, for use in a bearing in a precision machine. In another embodiment of the invention, the rails are convex curved in the lengthwise direction, for use in a bearing requiring compensation for misalignment of a shaft and the housing.
