PRODUCT DESCRIPTION / OVERVIEW
Advantage of the Ball Screws:
- Very high mechanical efficiency is achieved through rolling balls between the screw and nut, significantly reducing friction and delivering efficiency of approximately 94–97%.
- Excellent precision and repeatability are ensured by precision machining and tight tolerances, making ball screws ideal for CNC machines, semiconductor equipment, and metrology applications.
- Smooth and low-error motion is provided by the rolling action of the balls, resulting in vibration-free movement with minimal stick-slip effects.
- Reduced backlash and high rigidity are possible through preload options and high manufacturing quality, improving system stability and positioning accuracy.
- High load-bearing capability allows ball screws to carry significant static and dynamic axial loads, suitable for heavy-duty automation and machining applications.
- Long service life and high reliability result from rolling contact, which minimizes wear and reduces maintenance requirements compared to sliding screw systems.
- Energy and heat efficiency are improved due to low friction, leading to reduced power consumption, lower heat generation, and maintained precision over long operating cycles.

FAQs
A ball screw is a mechanical linear actuator that converts rotational motion into linear motion with minimal friction using a threaded shaft and recirculating ball bearings.
KSK ball screws offer high precision, smooth motion, high efficiency, low backlash, long service life, and the ability to handle high dynamic and static loads.
They are widely used in CNC machines, robotics, medical devices, automation systems, precision positioning systems, and any application requiring accurate linear motion.
The accuracy class (such as P1, P3) defines the maximum allowable deviation in linear travel over a given length. P1 is high precision, while P3 is standard precision.
Preload is the initial axial load applied to the ball screw and nut to eliminate backlash and improve rigidity. KSK offers various preloads, including 2-point or 4-point contact configurations.
