Abstract
A rolling guide unit as provided here is capable of raising the degree of flexibility in design and simplifying the control of lubricating oil and has a low sliding resistance to the rolling elements. The rolling guide unit is provided with a cylindrical memberthrough which a railpasses for it to slide on, raceway paths a constituted of a combination of the cylindrical memberand the rail, circuit paths b formed in the cylindrical memberand each making interconnection between the two ends of each of the raceway paths a by way of direction-changing recesses, and a plurality of rolling elementsplaced in the circuit paths b and the raceway paths a. The rolling elementscirculate in the circuit paths b and the raceway paths a in accordance with the relative movement between the railand the cylindrical member. The rolling guide unit is characterized by mounting holesformed in the cylindrical member; oiled membersrespectively installed in the mounting holes; and oil-supply memberseach provided along the contact faces of the rolling elementstraveling through either the raceway path a or the circuit path. The oil-supply membersare in contact with the oiled members
