Abstract
A linear motion ball bearing structure provided between a slider and a straight track rail for allowing the slider to move along a straight line of movement defined by the track rail is provided. The present linear motion ball bearing structure includes an endless travelling path in the slider and which includes a load path section, a return path section and a pair of connection path sections each connecting the corresponding ends of the load and return path sections, thereby defining a closed loop. Thus, the balls provided in the endless path roll from the load path section into the return path section through one of the connection path sections and then back into the load path section through the other of the connection path sections as the slider moves along the rail in one direction. The return path section is provided in the slider above and inward of the load path section, where the balls in the path are placed in rolling contact between the slider and the rail, so that the present structure may be made compact in size, particularly in its width.
