What are Ball Screws?
Ball screws are a kind of high precision mechanical components for converting rolling motion into linear motion. They are of threaded screw rods and ball nuts which realize the transmission of the force smoothly and efficiently while having minimal friction. By offering superior efficiency and control compared to traditional lead ball screws or hydraulic systems, ball screws enhance productivity, reduce energy consumption while support advancements in automation and precision engineering.
Product By Circulation Methods
With smaller assembly space and 1/3 the driving torque of traditional ball screws, the internal circulation series is widely used in high-precision industrial machinery, machine tools, and automation devices.
The external circulation series is especially suitable for high-speed applications, including CNC and high-precision machine tools, because its external return design supports heavy loads as well as low-noise operation.
Suitable for high-speed and high-precision applications, including CNC milling machines and medical equipment, end-cap circulation ball screws can be a good choice for demanding industrial applications.

Features of IMTEK Precision Ball Screws
High mechanical efficiency, great exceptional accuracy, wonderful repeatability and ability to handle heavy loads at a high speed are the outstanding features of IMTEK ball screws.

Thanks to IMTEK advanced thread grinding technology, our ball screws offer lead accuracy up to C3 grade (±5µm/300mm). Perfect for precision machining and robotic systems.

We support OEM customization: shaft end machining, special nut designs, extended travel lengths, or anti-backlash preloading per request.

The rolling contact between the ball and the screw shaft minimizes friction loss, achieving efficiency over 90% – reducing heat generation and energy consumption.

Our ball screws are engineered with hardened raceways, precision-ground surfaces, and optional lubrication systems to ensure extended durability in continuous-duty applications.

We respond within 24 hours with full datasheet, CAD models, and delivery timeline.
Why IMTEK Ball Screws?
Low-friction designs lower the wear and improve the durability. What’s more, it realizes its consistent performance and is essential in semiconductor manufacturing and 3D printing, which have demands for micron-level accuracy.
Ball screws also play an important role in systems with precise positioning and controlled motion requirement in industrial application. Widely used in CNC machine centers for tools positioning, robotics and automated manufacturing for conveyor or actuator control, ball screws are quite essential in semiconductor manufacturing and medical equipment, which have demands for micron-level accuracy.
With years of experience, IMTEK ball screws have its rigidly selected materials and are through intensive heat treating and processing techniques so that they have resulted in ball screws manufactured with high durability.

Product By Processing Methods


IMTEK has two featured types ball screws according to different processing methods: Roller ball screws and Precision Ground ball screws. The precision screws is made through a grinding process of the screw spindle while the rolled type is through rolling processing.
- Precision Ground Ball Screws
It provides high positioning accuracy and repeatability, and it can move smoothly and stably together with a long service life. Highly efficient ball screws are absolutely a good solution for kinds of different applications.
- Rolled Ball Screws
Generally, rolled screw has a smoother operation while lowering friction and backlash. Therefore, it gradually replaced the traditional ball screws and trapezoidal screws. Rolled ball screws eliminate axial play by preloading nut with a cost effective pricing compared to precision ground screws.
Frequent Asked Questions
Ball screws are efficient transmissions that converts rolling motion into linear motion, powered by the balls rolling in a circular groove in a threaded groove. Compared with ordinary trapezoidal screws, IMTEK ball screws have more than 90% mechanical efficiency, lower friction loss and longer life suitable for precision positioning and high-speed and heavy-duty scenarios (such as CNC machine tools, industrial robots).
Lead (distance traveled per spindle) directly affects speed and load capacity: Large lead screws are suitable for high speed and light load (automatic sorting line) while small lead models for high-precision and heavy-duty (mold processing). IMTEK provides lead 0.5mm~50mm customization options to meet your different requirement.
The lead error of the precision ground ball screws (accuracy C1-C5) is ≤±0.005mm, which is suitable for CNC machine tools or optical instruments. Rolled ball screws (C7-C10) are less costly, but the accuracy is suitable for general automation equipment. IMTEK’s grinding process meets international JIS standards to ensure nanoscale repeatability.
When choosing the correct ball screws, you should take some aspects into consideration: the load capability, accuracy level(C1-C10), the lead, the speed, the installation space and environment. Sometimes, the temperature and dust requirement are also important. IMTEK offers you a free product selector tool and engineer support as well to help to match the best solution.
Insufficient lubrication, improper preloading, wrong installation or foreign body intrusion are the common causes of loud noise or obvious vibration. It is recommended to clean regularly, use specified grease and check whether preloading matched the load. IMTEK ball screws are through high-precision grinding processing which can hugely reduces noises.
Life is usually evaluated in terms of operating distance (km) or fatigue life (L10). The main influencing factors include overload, shock load, poor lubrication and contamination. IMTEK screw rod is made of carburized steel material and surface hardening, and the service life can reach more than 1.5 times that of ordinary models.
