Product Advantages
1. High-speed linear movement
The 20mm lead provides fast travel per rotation, improving overall machine cycle efficiency.
2. Compact but efficient design
12mm diameter keeps the structure small while still allowing high-speed motion.
3. Smooth operation at moderate load
Suitable for light-duty systems with stable and continuous movement requirements.
4. Standardized structure
Easy to integrate into common small automation modules and linear systems.
5. Flexible customization
Supports different end machining and nut configurations based on equipment design.
Application Areas
SFAR1220 is commonly used in compact automation and light industrial systems, such as:
Small CNC auxiliary axes
High-speed 3D printers
Automated testing equipment
Light-duty pick-and-place systems
Optical adjustment devices
Laboratory automation systems
Small linear modules
Light industrial positioning systems
After-Sales Service
- Each SFAR1220 ball screw is inspected before shipment, including dimensional checks and surface quality verification.
- If any issue occurs under normal operation, technical support will be provided to analyze the cause and offer practical solutions.
- For long-term customers, stable batch consistency and replacement support can be arranged to ensure maintenance efficiency.
Customization Service
SFAR1220 supports multiple customization options:
- Custom shaft length
- End machining (threaded ends, stepped shafts, keyways, coupling ends, etc.)
- Nut structure (standard / anti-backlash types)
- Preload adjustment
- Accuracy grades (C7 / C5 / higher precision)
- Surface treatment based on working conditions
Most customization requests can be confirmed quickly with drawings or installation dimensions.
FAQ
Q1: What is SFAR1220 mainly used for?
A: It is used in compact systems where higher speed and small size are both required.
Q2: Is SFAR1220 suitable for precision feeding?
A: It is not designed for ultra-fine feeding; it is more suitable for fast motion and light loads.
Q3: What is the advantage compared to 1204/1205 models?
A: It offers much higher speed due to the larger lead, but with less fine control.
Q4: Can it replace other 12mm ball screws?
A: If diameter, lead, and installation dimensions match, it can usually be replaced, but drawings should be confirmed.
Q5: What lubrication is recommended?
A: Standard ball screw grease or light oil depending on speed and working environment.
