SFY02040 Ball Screw

Product descriptions

The SFY2040 Ball Screw is a high-performance linear drive component engineered for industrial applications demanding extreme linear velocities and rapid positioning in challenging environments.

As a specialized member of the High-Lead series, the SFY2040 features a unique 1:2 diameter-to-lead ratio, pairing a 20mm nominal diameter with an extraordinary 40mm lead. This configuration allows for massive linear displacement-traveling a full 40mm for every single 360-degree rotation. This enables ultra-high velocity at significantly lower motor RPMs, which minimizes heat generation, reduces centrifugal vibration, and extends the overall life of the drive system.

Furthermore, this "Armored" actuator utilizes a specialized "Y-Type" nut equipped with a reinforced wiper system designed to aggressively block dust and abrasive particles. Coupled with an internal end-cap circulation system for quiet operation, the SFY2040 is the cornerstone for high-throughput automated manufacturing, rapid packaging, and high-speed laser cutters.

Key Features & Engineering Advantages
Ultra-High Travel Velocity: The extreme 40mm lead enables linear speeds up to 8 times faster than standard 5mm pitch screws (at equivalent motor RPMs). This capability drastically reduces non-productive cycle times, maximizing machine throughput.
Superior Mechanical Efficiency: Utilizing optimized rolling friction mechanics, the assembly achieves transmission efficiency exceeding 90%, effectively converting rotational torque into linear thrust with minimal energy loss.
Extended Motor Service Life: High linear velocities are achieved without forcing the servo or stepper motor to operate at its maximum RPM limits. This reduction in rotational speed significantly minimizes thermal stress and mechanical wear on the drive unit.
High Rigidity & Precision: The robust 20mm diameter shaft provides the structural stiffness required to manage dynamic loads without deflection. Concurrently, precision-manufactured raceways ensure highly repeatable and accurate positioning.
Optimized Acoustics & Vibration: By requiring lower rotational frequencies for rapid travel, the high-lead design naturally dampens harmonic resonance and reduces overall operational noise, ensuring smoother motion profiles.
Compact Flanged Architecture: The single-nut SFY design is optimized for space-constrained installations while offering a robust, flanged mounting interface suitable for high-speed carriages.
