Product Advantages
1. Balanced speed and torque
The 20mm lead offers a good compromise between travel speed and driving force, making it suitable for general automation systems.
2. Strong load adaptability
Compared with high-lead models, SFYR2020 performs better under medium load conditions and is more stable in continuous operation.
3. Smooth and stable movement
The rolling contact design reduces friction, helping the system run with less vibration and noise.
4. Widely used standard size
20mm diameter is one of the most common industrial specifications, easy to match with motors, supports, and linear modules.
5. Flexible customization options
Supports multiple machining and assembly requirements depending on equipment design.
Application Areas
SFYR2020 is widely used in general-purpose automation and motion systems, such as:
CNC auxiliary motion systems
Industrial automation equipment
Laser cutting machines
Packaging and conveying equipment
Pick-and-place systems
Automated assembly lines
Measuring and inspection equipment
Linear motion platforms and modules
After-Sales Service
- Each SFYR2020 ball screw is inspected before delivery, including basic dimensional checks and running condition verification.
- If any quality issue occurs under normal working conditions, technical support will be provided to help identify the cause and propose a solution.
- For long-term cooperation customers, batch consistency and stable replacement supply can be maintained to reduce downtime risk.
Customization Service
SFYR2020 supports a wide range of customization options:
- Customized shaft length
- End machining (threaded ends, stepped shafts, keyways, etc.)
- Nut types (flanged, cylindrical, extended nut options)
- Preload adjustment based on application needs
- Accuracy grades (C7 / C5 / higher precision options)
- Surface treatment requirements (anti-wear, anti-rust, etc.)
In most cases, a drawing or installation dimension is enough for quick evaluation and production confirmation.
FAQ
Q1: What is the main advantage of SFYR2020 compared to smaller models?
A: It offers better load capacity and stability while still maintaining decent speed performance.
Q2: Is SFYR2020 suitable for high-speed applications?
A: It can run at moderate speeds, but it is more suitable for balanced performance rather than extreme high-speed motion.
Q3: Can it be replaced with other 20mm ball screws?
A: If the lead, diameter, and end machining are the same, it is usually interchangeable, but drawings should always be checked.
Q4: How long can it be produced?
A: Length can be customized, but very long shafts may require additional support design to ensure stability.
Q5: What lubrication is recommended?
A: Standard ball screw grease or oil is recommended, depending on operating speed and environment conditions.
