The static and dynamic load ratings of PBC Linear ball screws were determined by the ISO 3408 standard calculations.
The dynamic load rating, Ca, is the load at which 90% of properly lubricated identical ball screws will reach 1 x 106 revolutions.
The static load rating, Coa, is an axial static load which will produce a permanent deformation at contact points of the steel balls to ball grooves equal to 0.01% of the ball diameter.
