- What does “DN value” mean?
- The DN value is an indicator of whether components making up the ball circulation path can be used without sustaining damage.
The DN value is calculated using the following formula:
DN value = ball center-to-center diameter (mm) × operating speed of the screw shaft (min⁻¹)
Select an appropriate speed that does not exceed the permissible DN value for each model.
