Standard Worm Gear Screw Jacks

JUMBO® 1 - 5 (-500 kN)
Driven by a precision worm gearing (screw keyed to the worm wheel), the rotary motion of the screw is translated into linear motion of the travelling nut on the screw

MULI® 0 - 5 (-100 kN)
The rotary motion of precision worm gearing (worm shaft and internally threaded worm wheel) is converted into axial linear motion of the screw, which travels through the gear box housing. The load is attached to the end of the screw.

Optimize your design with a custom worm gear screw jack solution.

Worm Gear Screw Jacks Features
• MULI® and JUMBO® series are manufactured for loads from 5 to 500 kN
• Cubic housing, standardized mounting material and end-pieces, and pre-drilled flange holes permit easy installation of motor, gears, and shaft encoder
• All models designed for tensile and compressive loads
• Complete range of motors and accessories is available
• All models designed for pushing forces, pulling forces, and for position independent functioning
• High and low speeds available due to two different ratios
• Synchronization of several screw jacks is easily accomplished

Worm Gear Screw Jacks Options
• Version N- screw rotation prevented by its permanent attachment to guided load
• Version V- anti-rotation device; recommended when screw jack cannot be secured externally to prevent rotation
• Version R- rotatory motion of the screw jack is translated into linear motion via travelling nut Note: nut must be purchased separately
• Gear Ratio H- one full turn of the shaft produces a stroke of 1 mm
• Gear Ratio L- one full turn of the shaft produces a stroke of 0.25 mm
