What Is an SFU1204 Ball Screw Nut?
An SFU1204 ball screw nut is a precision linear motion component designed for converting rotary motion into accurate linear movement. It works together with a matching ball screw shaft to deliver smooth, efficient motion transfer for industrial equipment.
The “1204” specification in its name refers to the core dimensions of the assembly:
- 12 mm screw shaft diameter
- 4 mm lead (the linear travel distance per full revolution of the screw)
Compared with traditional lead screws, ball screw systems provide significant performance improvements:
- Lower friction for smoother operation
- Higher transmission efficiency, up to 90%+
- Better positioning accuracy for repeatable tasks
- Reduced backlash for more precise control
- Longer service life with less maintenance
SFU1204 assemblies are widely used in CNC routers, engraving machines, 3D printers, and industrial automation systems requiring smooth and repeatable motion control.
C5 vs C7 Ball Screw Accuracy
Choosing the right accuracy grade is critical to matching your application needs with cost efficiency. We offer multiple precision grades to fit different industrial requirements:
For most industrial automation applications, C7 grade offers an excellent balance between cost and performance, while C5 is preferred for projects that demand higher repeatability and tighter tolerances.
How We Reduce Ball Screw Backlash
Backlash refers to the axial play between the nut and screw shaft, which can directly affect CNC machining accuracy and positioning repeatability. For precision motion systems, eliminating or minimizing this play is essential to ensure consistent, reliable performance.
Our custom ball screw nuts can be manufactured with multiple solutions to address this issue:
- Preloaded ball designs to eliminate free play
- Oversized ball options for increased rigidity
- Double-nut configurations for adjustable preload
- Precision-ground raceways for tighter dimensional control
These solutions help minimize axial play and improve motion stability in high-speed CNC and automation systems. Industry users and equipment builders often prioritize preload and oversized-ball configurations to improve repeatability and reduce vibration in motion systems.

Frequently Asked Questions
Can you manufacture non-standard ball screw nuts?
Yes. We support custom dimensions, preload configurations, flange designs, and material requirements based on customer drawings or application needs. Our engineering team can work with you to develop solutions that fit your unique equipment requirements.
What information is required for quotation?
To provide you with an accurate quote, please share: screw diameter and lead, accuracy grade, load requirements, application environment, and 2D/3D drawings if available. This helps us tailor the solution to your exact needs.
What is the difference between C5 and C7 ball screws?
C5 offers higher positioning accuracy and repeatability, making it ideal for precision applications like semiconductor manufacturing. C7 is more cost-effective, making it a popular choice for general industrial automation and standard CNC equipment where a balance of performance and cost is preferred.
Do you support small batch production?
Yes. We understand that equipment developers and small manufacturers need flexible order sizes. We support prototype and low-volume orders to support your equipment development, testing, and small-scale production needs, without requiring large minimum order quantities.
Can your products replace HIWIN or TBI components?
We can manufacture compatible dimensions and customized alternatives according to your specifications. Many of our OEM customers use our components as reliable replacements for branded parts like HIWIN or TBI, helping them reduce supply chain costs while maintaining consistent performance.
