High-Speed Screw Jacks: RMY, RSY & J0Y Series – Superior Efficiency
1. Product Overview
The High-Speed Screw Jack Series features a breakthrough design that combines a compact, lightweight form factor with high-velocity operational capabilities. This series is the perfect alternative to standard screw jacks when your system demands fast duty cycles and optimized transmission efficiency.
2. Key Technical Features
-
Ultra-Fast Response: By utilizing quadruple-thread screws and a large lead, this series achieves speeds 2 to 5 times faster than traditional (Type H) screw jacks at the same input speed.
-
Streamlined & Versatile Design: The compact housing saves valuable installation space. Its intelligent design allows for flexible mounting from both the top and bottom surfaces.
-
High Mechanical Efficiency: Optimized friction reduction ensures smoother operation even at high-speed ranges.
-
Important Safety Note (Non-Self-Locking): Due to the large screw lead, this series is non-self-locking. A dedicated braking system is mandatory to hold the load safely when the motor stops.
-
Customizable Options: Fully compatible with bellows (dust covers), limit switches, and RC encoders for high-precision stroke control.
