Technical Reference (Industry typical structure)
In common 40×40 ball screw designs, the high lead is achieved through multi-start thread construction, allowing fast linear motion with reduced rotational input (typical for high-speed ball screw systems in automation equipment).
Product Advantages
1. Extremely high travel speed
The 40mm lead provides very large movement per revolution, significantly improving machine efficiency.
2. Suitable for long-stroke automation systems
Ideal for equipment that needs fast positioning across long distances.
3. Reduced cycle time
High lead design helps shorten overall machine operation time.
4. Stable performance in industrial environments
When properly supported, it maintains smooth motion even under continuous operation.
5. Flexible configuration options
Supports different nut structures, preload options, and machining requirements.
Application Areas
SFAR4040 is widely used in high-speed industrial automation systems such as:
Large linear motion modules
Automated transfer and handling systems
Packaging and sorting machinery
Laser cutting auxiliary motion systems
High-speed industrial production lines
Pick-and-place systems with long stroke
Material conveying and positioning systems
General automation equipment requiring fast feed motion
After-Sales Service
- Each SFAR4040 ball screw is inspected before shipment, including dimensional checks and basic functional verification.
- If any issue occurs during normal operation, technical support will be provided to analyze the cause and assist with practical solutions.
- For long-term cooperation, stable batch consistency and replacement supply can be arranged to support maintenance planning and reduce downtime risks.
Customization Service
SFAR4040 supports a full range of customization options:
- Shaft length customization
- End machining (threaded ends, stepped shafts, keyways, coupling ends, etc.)
- Nut structure (standard / anti-backlash / preloaded types)
- Preload adjustment
- Accuracy grades (C7 / C5 / higher precision)
- Surface treatment based on working environment
Most customization requests can be confirmed quickly with drawings or installation dimensions.
FAQ
Q1: What is SFAR4040 mainly used for?
A: It is used in high-speed linear systems where large travel distance per rotation is required.
Q2: Is SFAR4040 suitable for precision feeding?
A: No, it is designed for speed and efficiency rather than fine positioning.
Q3: What is the advantage of 40mm lead?
A: It significantly increases linear travel per revolution, improving cycle time.
Q4: Can it replace other 40mm ball screws?
A: If dimensions and installation structure match, it can usually be replaced, but drawings must be confirmed.
Q5: What lubrication is recommended?
A: Standard ball screw grease or industrial oil depending on operating speed and load conditions.
