lubricant within the body of the ball nut. Speeds that are high for ball screws are no problem for grease, so speed is not a criterion for selection. For example, grease is the accepted lubricant for machine tool spindles with dn (bearing bore, mm x rpm) values as high as 1,000,000. For ball screws, dn values rarely exceed 100,000.

The Ball Screw requires a minimal starting torque due to its rolling motion, and does not cause a slip, which is inevitable with a sliding motion. Therefore, it is capable of an accurate micro feeding. Fig.4 shows a travel distance of the Ball Screw in one-pulse, 0.1-μm feeding. (LM Guide is used for the guide surface.)
