It is important for a high-lead ballscrew to be with characteristics of high rigidity, low noise and
PMI takes its patented design and treatments to achieve the following characteristics:
High DN Value
Max. DN Value: 220,000
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.
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.
