SWL2.5T Self-Locking Screw Jack – Assembly Type, Structure Type & Shaft Orientation Diagram
SWL2.5T Self-Locking Screw Jack – Assembly Type, Structure Type & Shaft Orientation
The SWL2.5T screw jack is a self-locking worm gear screw lift with 2.5 ton (25 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 |
| 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 SWL2.5T 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)
Output configurations:
Type A: Screw work end at top – upward pushing
Type B: Screw work end at lower side – downward pulling
Selection Guide
Choose Structure Type: Type 1 for vertical lifting with screw movement; Type 2 for compact designs with nut movement
Choose Assembly Type: Type A for upward lifting; Type B for downward pushing
Choose Shaft Orientation: Left, right, or dual-side input based on motor position
Specify Stroke: Custom stroke available per your requirements
