Precision Ball Screw, End-Cap Type Series FDDC

The threaded section features an average, highly accurate ball circle diameter (BCD), enabling the ball screw to achieve stable and consistent preload torque and reduce noise levels.

Feature
For high-lead ball screws, high rigidity, low noise, and temperature rise control are extremely important. By adopting the following countermeasures and patented designs, we achieve the following characteristics:

High DN value

The DN value can be as high as 220,000.

Low noise

The threaded section features an average, highly accurate ball circle diameter (BCD), enabling the ball screw to achieve stable and consistent preload torque and reduce noise levels.

The reflux system, made of high-rigidity, wear-resistant reinforced plastic material, ensures that the steel balls operate with a low, smooth, and gentle sound.

Save space

The nut’s length is shortened, and its outer diameter can be reduced by 20% to 25%, resulting in an overall volume reduction of approximately 50%.

Cycling mode

The return path is tangent to the lead angle and also tangent to BCD, which can effectively improve its smoothness.
