Chiaravalli – Mechanical Worm Screw Jacks – Catalogue

Use cases
Linear lifting and positioning with synchronized motion using trapezoidal or ball-screw jacks, in translating or rotating-screw configurations.

Engineering items

• Load rating (static/dynamic), column buckling margin and critical screw speed.
• Self-locking behavior (trapezoidal) vs. efficiency and backdriving (ball screw).
• Accessories: bellows, anti-rotation guides, limit switches, encoders and safety nuts.

Sizing guidance

• Define load, stroke, speed and simultaneity (single vs. multi-point).
• Check duty cycle and thermal rise in continuous lifts; choose screw lead accordingly.
• Plan synchronization via shafts/bevel gearboxes; verify braking and stops for safety.
