It is important for a high-lead ballscrew to be with characteristics of high rigidity, low noise and thermal control. PMI takes its patented design and treatments to achieve the following characteristics:

High DN Value
Max.DN Value: 220,000

Low Noise
The average and accurate ball circle diameter (BCD) through
whole threads make the ballscrews to obtain the stable and consistent
drag torque as well as to reduce the noise. The audio frequency is low
and deep due to the designed of plastic circulation system.

Space Saving
The ballnut diameter reduces 20%~25% substantially and the
length of nut is shorter. The total space shall be reduced to
approximately 50% consequently.

The specially designed pathway of the Recirculation System makes a contact with lead angle and also with BCD in the same tangency, improving its smoothness eff ectively.
