AI Overview
Key Features and Options
- Design Principle: The screw rotates within the housing (fixed axial position), while the flanged nut traverses, providing linear motion.
- Compact Size: Ideal for mounting in small areas where a "translating" (push-pull) screw would interfere with the structure.
- Specifications: Often available in small sizes with 500 lb (approx. 227 kg) capacity, with typical Screw Diameters of 14mm-16mm.
- Options: Manual handwheel or motorized input (worm gear) is common.
Typical Applications
- Material Handling: Small lifting and positioning platforms.
- Packaging Machinery: Adjusting guides and tensioners.
- Solar Tracking: Precision positioning.
- Factory Automation: Linear movement in tight spaces.
Common Manufacturers/Series
- Lude Transmission: SJA Series (Small Cubic Machine Screw Jack with Traveling Nut).
- Maedler North America: Worm gear screw jack NPT, Version C.
- Jacton Industry: 5t anti-rotating screw jack.
- Joyce Dayton: Keyed for Traveling Nut Design (KFTN) jacks.
For space-restricted applications, a 500 lb mini traveling nut screw jack from Jacton Industry or a Type C/rotating screw jack from Maedler North America is suitable.
