1.2.1 Strength of the Ball Screw Spline
If a load exceeding the allowable value is applied to the ball screw spline, it may not work
properly due to deformation or breakage of the shaft. If the ball screw spline is applied
the load exceeding the allowable value, it is necessary to replace the ball screw spline unit.
The allowable loads differ depending on distance where the load is applied to. For
calculating the allowable load, see the calculation formula below.
[Allowable bending moment]
G6: M=27,000 N ∙ mm
Example: If 270 N load is applied
at 100 mm from
the end of the spline nut
[Moment]
M=F ∙ L ＝ 100
∙ 270
＝ 27,000 N ∙ mm
