PROBLEM TO BE SOLVED: To achieve a high quality machining surface and high shape precision by restraining a minute amplitude of undulation as much as possible. SOLUTION: An arbitrary row of cylindrical rollers is shifted for a half of a pitch with respect to an adjacent row of the cylindrical rollers in the limited rolling guide having rows of the cylindrical rollers arrayed parallel, which is the rolling guide for guiding a moving element of a machine tool.
