ABSTRACT:
A ball screw-nut machine is disclosed in which a number of ball rolling elements are interposed between the spiral thread of a ball screw shaft and a ball nut, wherein the opposed threads of the shaft and nut define a load element rolling space. The balls circulate endlessly in plural endless circulation paths which are each formed by the combination of the load element rolling space and a ball circulating path. A lubricant supply member is disposed between the endless circulation paths so as to supply the balls and threads with lubricant. The lubricant supply member is formed of a lubricant-containing polymer. As a result, stable lubrication of the machine is ensured for a long time.
