It is important for a high-lead ballsrew 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 effectively.
