SFY5050 Ball Screw

SFY5050 Ball Screw

Product descriptions

Configuration: 50mm Diameter / 50mm Lead (1:1 "Square" Ratio).
Extreme Velocity: Delivers 50mm of linear travel per revolution, achieving rapid traverse speeds up to 100m/min.
Nut Design: Specialized "Y-Type" flanged nut featuring internal end-cap ball recirculation for low-noise, high-speed operation.
Environmental Protection: Equipped with reinforced wipers engineered to exclude abrasive dust, metal grit, and particulate ingress.
Long-Stroke Stability: The massive 50mm shaft provides exceptional column strength, preventing deflection and vibration over extended gantry spans.
Applications: Ideal for heavy transfer lines, large CNC routers, and high-throughput automated warehousing.

Product Advantages

Extreme Velocity at Safe RPMs:
To propel a heavy carriage at 50 meters per minute, a standard 5010 (10mm lead) screw would need to rotate at an impractical 5,000 RPM. In contrast, the SFY5050 achieves 50m/min at just 1000 RPM. This 1:1 diameter-to-lead ratio keeps the massive 50mm shaft operating well below its critical speed limit, ensuring stable, vibration-free motion on large-format machinery.
The "Y-Type" Enhanced Debris Shield:
When operating at velocities of 50-100m/min, standard plastic seals can "hydroplane" over fine dust, drawing contaminants directly into the nut. The SFY series features a patented "Y-Type" enhanced dust-proof scraping mechanism. This reinforced seal maintains tight contact with the thread grooves even at maximum velocity, effectively locking out abrasive powders, metal grit, and industrial soot to prevent premature wear.
High-Mass Vibration Damping:
A 50mm solid steel shaft possesses significant mass. This inherent structural weight acts as a natural vibration damper. It effectively absorbs the kinetic shock generated by the rapid acceleration and deceleration of heavy payloads, maintaining system rigidity and accuracy.
