To provide a linear movement guide bearing device improved in workability, noise characteristic and durability by interposing a separator T having an outer diameter as large as possible at low cost.
In the linear movement guide bearing device including the separator T interposed between adjacent balls of balls K moving along a curved circulating passage 8, in which the balls K are rolled while contacting with concave parts W at both axial ends of the separator T and further with a guide face 8a of an outer guide member 5 and a guide face 8b of an inner guide member 9, the outer diameter dimension of the separator T is set to a maximum outer diameter dimension L or more in a state where the balls K are rolled while simultaneously contacting with both the inner and outer curved faces 8a and 8b of the curved circulating passage 8, and the curvature radius of the guide face 8b of the curved circulating passage 8 is reduced to a size not contacting with the separator T.
