examples of selecting a ball screw thk

The Simple-Nut Ball Screw is an offset preload type in which a phase is provided in the middle of a single ball screw nut and an axial clearance is set at a below-zero value (under a preload) The Simple-Nut Ball Screw has a more compact structure and allows smoother motion than the con-ventional double-nut type (spacer inserted between two nuts) Lithium thickener allows this grease to withstand over 30% more pressure than our standard ball screw grease It is long lasting and resists heat and moisture NLGI viscosity grade is a rating of a grease's consistency NLGI 2 is about the consistency of peanut butter Weld load measures a grease's ability to withstand pressure in kilograms of force (kgf)

Aug 24 2012Ball recirculation inside the ball nut can affect precision and repeatability As a result ball nuts are available with a range of pre-load options to reduce or remove the axial play as they rotate around the screw This allows for better repeatability for example because no motion is lost from the clearance in the balls as they reengage

D = Ball circle diameter (mm) N = Revolutions per minute (min-1) Dynamic Load Rating C a and Life The basic load rating C a is the load in the shaft direction with 90% of a group of the same ball screws operating individually will reach a life of 10 6 (1 million) revolutions Where: L = Rotation life [rev] C a = Basic dynamic load rating [N
