• Basic dynamic and static load ratings indicate values for one slider.
• Basic dynamic load rating of linear guide is a load that allows for a 50-km rating fatigue life and is a vertical and constant load on the ball

mounting surface.
• Basic dynamic load rating of ball screw is load in the axial direction that allows 90% of ball screws of a group of the same Toughcarriers to

rotate 1 million revolutions under the same condition without causing flaking by rolling contact fatigue.
• Basic dynamic load rating of support bearings is load that allows 1 million revolutions under the same condition.
• Basic static load rating is load that results in combined permanent deformations at contact points of rolling elements and rolling surfaces of

respective parts at a diameter of 0.01%.

• The basic static moment is the value when rolling contact pressure of balls exceeds 4 000 N/mm2.
• If you plan to apply extremely heavy loads, please consult NSK for estimation of fatigue life.
