High Lead Ball Screw
High Lead Ball Screw
High lead ball screws are high-precision transmission components that convert rotary motion into linear motion. They have a large lead (the linear distance the nut travels in one revolution of the screw), making them suitable for applications requiring rapid movement or large stroke transmission.
High Lead Ball Screw Key Selection Parameters:
Lead (L): Determines the travel speed and must be matched with the motor speed.
Nominal diameter (d): Affects load-bearing capacity and rigidity; a larger diameter results in a stronger load.
Precision grade: such as C7, C10, selected according to equipment requirements.

High Lead Ball Screw Features
It is important for a High-lead Ballscrew to be with characteristics of high rigidity, low noise and thermal control. PMI ‘s designs and treatments are taken for following:
1. High DN Value
The DN value can be 130,000 in normal case. For some special cases, for example in a fixed ends case, the DN value can be as high as 140,000. Please contact our engineers for this special application.
2. High Speed
PMI ‘s High-speed Ballscrews provide 100 m/min and even higher traverse speed for machine tools for high performance cutting.
3. High Rigidity
Both the screw and ballnut are surface hardened to a specific hardness and case depth to maintain high rigidity and durability.
Multiple thread starts are available to make more steel balls loaded in the ballnut for higher rigidity and durability.
4. Low Noise
Special design of ball circulation tubes offer smooth ball circulation inside the ballnut. It also makes safe ball fast running into the tubes without damaging the tubes.Accurate ball circle diameter (BCD) through whole threads for consistent drag torque and low noise.
High Lead Ball Screw Application:
1. High-speed equipment: such as automated production lines and laser cutting machines, where rapid positioning is required.
2. Heavy-duty machinery: such as gantry machining centers and presses, requiring high rigidity designs.
3. Precision instruments: medical equipment and semiconductor manufacturing, relying on high precision and stability.
