JSS-20T Stainless Steel Jack Features: JSS-20T stainless steel jack, also named 20 ton worm gear stainless steel machine screw jacks, which is specifically designed for positioning and lifting applications that are located in wet, corrosive and harsh environments.
1. Maximum static load capacity 20 ton, its working load depends on stroke, travel speed and working conditions. 2. Lifting screw sizes Tr 65x12. Customized stroke length. 3. Upright installation, Inverted installation. 3. Translating screw, anti-rotation (keyed) screw and rotating screw configurations. 4. High ratio 8:1, Medium ratio 12:1, Low ratio 24:1. 5. Can be connected together in systems so that multiple units stainless steel jacks can be operated and controlled together. 6. Operated by handwheel or crank handle, Driven by electric motor with motor flange or coupling.

JSS-20T Stainless Steel Jack Specifications * Note: The dark gray figures in the tables indicates operational restrictions due to thermal limits. Static only (dynamic not permitted). Selection of screw jacks using these figures should only be carried out in consultation with our engineers. When your selection is made within the areas dark gray, you will need to reduce duty cycle or choose larger model screw jacks in order to allow effective heat dissipation. * Conditions: Duty cycle 20%/h or 30%/10min, 20 °C ambient temperature. * Gear Ratios: H: high ratio, L: slow ratio. * Nm: Input torque required, kW: Input power required.
