Ball-Screws
Ball screws are precision mechanical components used to convert rotational motion into linear motion efficiently and with minimal friction. They are widely used in CNC machinery, industrial automation, robotics, and aerospace applications due to their ability to provide smooth and accurate movement. Unlike traditional lead screws, ball screws use recirculating ball bearings, which reduce wear and increase efficiency. Their accuracy is categorized into different grades, such as C3, C5, C7, and C10, indicating the level of precision in movement.

Ground Ball Screws Solutions
Rolled Ball Screws Solutions
Ground Ball-Screws
Ground ball screws are manufactured through a precision grinding process, which ensures tight tolerances and superior accuracy. This method results in a highly smooth surface and minimal deviation, making ground ball screws ideal for applications requiring high precision, such as CNC machining, semiconductor manufacturing, and aerospace equipment. They are commonly available in C0, C1, C2, and C3 accuracy grades, offering the highest level of precision. Because of their complexity in manufacturing, ground ball screws tend to be more expensive than rolled alternatives.
Rolled Ball-Screws
Rolled ball screws are produced through a thread rolling process, which is more cost-effective and faster than grinding. While they may not achieve the ultra-high precision of ground ball screws, rolled ball screws are suitable for many industrial applications, including general automation, medical devices, and transport systems. They are commonly available in C5, C7, and C10 accuracy grades
