<p><P>PROBLEM TO BE SOLVED: To enable a linear motion ball bearing to have sufficient bearing power or the support action, and to sufficiently compensate for a matching error between relatively movable components, by economically manufacturing the linear motion ball bearing, by improving the linear motion ball bearing. <P>SOLUTION: This linear motion ball bearing 1 movably supports a shaft-shapes guide rail 2 in the longitudinal direction, and has a sleeve-shaped cage 4. A ball circulating part 9 is arranged in a cutout 5 of the cage, and the ball circulating part 9 has a support division for receiving a ball 90. The ball is rollably supported by a support track member 8 installed in the cage. The support track member is in a form having an outer surface in the radial direction curved in a projecting shape to the outside to be supported by an inner surface of a component 3 for surrounding the guide rail, and the outer surface is formed of a rib-shaped protrusion part, and the protrusion part extends in the longitudinal direction of the support track member. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
