Looking for a compact, high-efficiency ball screw for precision industrial equipment and lab instruments? Our custom 8mm diameter miniature ball screw from Shuntai delivers reliable rotary-to-linear motion conversion, fully customizable in shaft length and end machining to match your unique equipment drawings.
Mini ball screws are the core component that seamlessly converts rotational motion into precise linear movement, and vice versa. Composed of a screw shaft, ball nut and circulating steel balls, this mini ball screw redefines traditional sliding transmission by adopting rolling friction design. The drastically reduced friction resistance enables smoother, quieter and more energy-efficient operation, making it a staple for all types of precision machinery and analytical instruments worldwide.

Why Choose Our 8mm Mini Ball Screw?
1.Premium GCr15 Bearing Steel Construction
We adopt high-grade GCr15 bearing steel as raw material. After precise heat treatment, the shaft and nut gain outstanding hardness, wear resistance and anti-fatigue performance, laying the foundation for long-term stable operation.
-
2.Two Processing Options for Different Precision Needs
- • Rolled ball screw: Cost-effective, fast delivery, ideal for general automation equipment
- • Ground ball screw: Ultra-high positioning accuracy, low backlash, perfect for high-precision testing instruments and medical devices
- 1.Full Customization Support
No standard fixed sizes limit your design. We can machine the screw end to your required shape, thread, mounting shoulder, and adjust the total shaft length strictly following your technical drawings. The 8mm shaft diameter hits the sweet spot between compact size and load capacity for miniature automation modules.
-
2.Long Service Life & Low Maintenance
Thanks to rolling friction transmission, friction loss is far lower than trapezoidal lead screws. Less wear on internal balls and raceways cuts down maintenance frequency and replacement costs for your production line.
-
3.Fast Lead Time & Convenient Global Shipping
Standard custom orders finish production within just 7 working days. We ship all goods from Shanghai Port, with mature logistics cooperation to support sea, air and express delivery to all global regions.
