SWL5T Self-Locking Screw Jack – Assembly Type, Structure Type & Shaft Orientation Diagram
SWL5T Self-Locking Screw Jack – Assembly Type, Structure Type & Shaft Orientation
The SWL5T screw jack is a self-locking worm gear screw lift with 5 ton (50 kN) load capacity. It is available in multiple structure types, assembly types, and shaft orientation configurations to match your specific application requirements
SWL series reducer jack structure type
| Structure Type | Description | Best For |
| Type 1 | Worm gear threadedly connected to screw; screw moves axially (rotates + translates) | Vertical lifting, precise positioning |
| Type 2 | Worm gear keyed to screw; screw rotates, nut moves axially) | Compact installations, high-speed operation |
Available Assembly Types
| Assembly Type | Movement Direction | Application |
| Type A | Screw (or nut) moves upward | Lifting loads from below |
| Type B | Screw (or nut) moves downward | Pushing down or suspended loads |
Shaft Orientation Diagram
The SWL5T features dual-side input shafts supporting IEC, NEMA, and servo motor adapter flanges
Input shaft options:
Left-side input
Right-side input
Dual-side input (motor on either side)
