SFY Ball Screw

The SFY Ball Screw features an innovative end cap circulation design with a large lead structure, delivering high-speed performance and high Dm-N rating while maintaining low noise and smooth operation. Its unique circulating system ensures excellent running stability, even under demanding conditions.

Equipped with a patented sealing system, the SFY series offers outstanding dustproof protection, significantly extending service life. With high precision, zero backlash, and excellent rigidity, it is ideal for applications requiring accuracy and stability.

The series provides a wide range of diameter and lead options, ensuring strong versatility and adaptability across various industrial applications. Its optimized design guarantees smooth motion, high durability, and reliable performance over long-term use.

SFY and SFE ball screws share a similar structural concept, especially in their sealing design. Both series are equipped with thin elastic end seals on both sides of the ball nut, effectively preventing dust, chips, and contaminants from entering the system, ensuring cleaner operation and extended service life.

However, there are key differences in performance and application:

SFY Ball Screw

Designed for high-speed and low-noise applications, the SFY series features an optimized circulation system and enhanced sealing design. It offers smoother operation, better dynamic performance, and improved stability under high-speed working conditions. The upgraded sealing system also provides stronger dust protection, making it suitable for demanding industrial environments.

SFE Ball Screw

The SFE series focuses on general industrial applications with reliable performance and cost efficiency. It also adopts dual-side elastic end seals to ensure effective dust protection, making it suitable for standard machinery where extreme speed is not the primary requirement.

Key Takeaway

While both SFY and SFE ball screws feature advanced sealing systems with excellent dust-proof capability, SFY is optimized for higher performance and high-speed operation, whereas SFE provides a more economical solution for general-purpose use.
