Ball Screws for Precision Motion Systems | Motiontek

What Are Ball Screws?

Ball screws are precision motion transmission components that convert rotary motion into linear motion with extremely high efficiency.
They operate through the rolling of precision balls between a threaded screw shaft and a matching nut, dramatically reducing friction compared to conventional sliding systems. This makes ball screws an essential element in CNC machines, automation equipment, industrial robots, and semiconductor manufacturing tools, where accurate and repeatable positioning is critical.

Compared with lead screws, ball screws provide much higher transmission efficiency (up to 90–98%), lower heat generation, and more consistent performance over time.
Their design allows micron-level lead accuracy, smooth movement, and excellent rigidity — all of which contribute to stable, long-term operation in precision machinery.

As a professional Chinese ball screw manufacturer, Motiontek designs and produces a complete range of ball screws to meet different application needs.
Our product lineup includes:

• Internal Circulating Ball Screws — compact structure with low vibration, suitable for limited installation spaces.
• External Circulating Ball Screws — easy maintenance and excellent heat dissipation under heavy-duty use.
• End Cap Series Ball Screws — high-speed design with quiet running and smooth recirculation paths.

Each product undergoes CNC thread grinding, heat treatment, and 100% inspection for lead accuracy, preload, and concentricity. We ensure every unit meets international standards such as ISO and GB/T, guaranteeing reliable motion in demanding industrial environments.

Whether you are designing a new machine or upgrading existing systems, Motiontek’s ball screws deliver precise motion, consistent performance, and long service life — supported by flexible MOQ and full OEM customization services.
