50 kN Capacity Higher Lifting Speeds Screw Jacks with Ball Screws

Jacton 50 kN capacity higher lifting speeds screw jacks with ball screws are employed for lifting, pulling, moving, aligning any kind of load with a perfect synchronism. And suitable for high services as well as for a very rapid, quick and precise positioning. Note: highly efficient and require a brake or other external locking device to hold position. The ball screw sizes 40x10, worm gear ratios 7:1 and 28:1. 


Features of 50 kN Capacity Higher Lifting Speeds Screw Jacks with Ball Screws
1. Upright or inverted units with maximum static load capacity 50 kN in tension or compression.
2. Required input torque to approximately one-third the torque required for the machine screw jack. They also require a brake motor or external locking device to hold position.
3. Ball screw sizes 40mm diameter, lead 10mm (single start ball nuts and ball screws).
4. Worm gear set gear ratios 7:1 and 28:1 ratios.
5. There are no standard travel lengths and each ball screw jack is built to specification. 
6. Standard configurations: upright or inverted translating ball screw jacks, upright or inverted translating with anti-rotation ball screw jacks, and upright or inverted rotating ball screw jacks.
7. They can be driven by different motors: electric motors, dc motors, gear motors, as well as hydraulic or pneumatic motors. Also they can be driven by hand wheels or cranks or with any other kinds of transmission.
8. Can be applied singularly or in groups as a synchronous lifting system which properly connected with drive shafts, universal joints, and bevel gearboxes.

Structures of 50 kN Capacity Higher Lifting Speeds Screw Jacks with Ball Screws
1. Ball screw and nut made from hardened alloy steel with hardened bearing balls carrying the load between nut and screw.
2. Worm input shaft in case-hardened steel C45.
3. High strength aluminum bronze worm gears (drive sleeve).
4. Housing of nodular cast iron.

Specifications of 50 kN Capacity Higher Lifting Speeds Screw Jacks with Ball Screws
The specifications of 50 kN capacity higher lifting speeds screw jacks with ball screws include maximum load capacity, worm screw diameter and pitch, worm gear ratio, allowable maximum input power, torque and speed and overall efficiency etc. 

1. Conditions: within 20% running time/60 minutes or within 30% running time/10 minutes, 20 ��C ambient temperature. Maximum allowable input power (high ratio) 2.2kw, maximum allowable input power (slow ratio) 1.1kw. 
2. Note: The dark gray figures in the tables indicates operational restrictions due to thermal limits. 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 shaded dark gray, you will need to reduce duty cycle or choose the bigger size screw jack in order to allow effective heat dissipation.
3. H=high ratio 7:1 (1.43mm stroke for one input turn), L=slow ratio 28:1 (0.36mm stroke for one input turn).
4. Nm=input torque required, kW=input power required. 
5. Selection of screw jacks using above figures should only be carried out in consultation with Jacton engineers.
