Abstract
A crossed roller type linear motion rolling contact bearing assembly includes a straight rail and a slider mounted on the rail slidably therealong. An endless circulating path is defined in the slider, in which a plurality of rollers are provided. Since the path includes a load section where the rollers provide a rolling contact between the slider and the rail, the slider may slidably move along the rail. Also provided in the endless path are a plurality of roller separators each of which is interposed between two adjacent rollers thereby keeping these two rollers as spaced apart from each other at all times. The separator has a pair of roller-receiving recesses for holding therein the associated rollers in a crossed arrangement, and each of the roller-receiving recesses is so shaped that the roller received therein can change its orientation over a predetermined range so as to maintain a predetermined positional relationship between the two rollers received in the recesses on both sides of the separator.
