Description:
50kN Capacity Higher Lifting Speeds Screw Jacks with Ball Screws Configurations: Upright Translating Ball Screw Jack, Inverted Translating Ball Screw Jack, Upright Rotating Ball Screw Jack, Inverted Rotating Ball Screw Jack, Double Clevis Ball Screw Jack, Upright Keyed Ball Screw Jack, and Inverted Keyed Ball Screw Jack.


Main Features
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 and Materials
- Ball screw and nut is made from hardened alloy steel with hardened bearing balls carrying the load between nut and screw. Ball Screw: SCM 450, S55C, Hardness: HRC 58-62. Ball Nut: SCM415H, Hardness: HRC 58-62. Steel Ball: SUJ2, Hardness: HRC 60.
- Worm shaft material - C45 steel, heat treatment. Customized stainless steel 304, 316.
- Worm wheel material - high strength aluminum bronze.
- Housing material - ductile iron, available in stainless steel 304. 


Specifications
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. H=high ratio 7:1 (1.43mm stroke for one input turn), L=slow ratio 28:1 (0.36mm stroke for one input turn).
3. Nm=input torque required, kW=input power required. 
4. Selection of screw jacks using above figures should only be carried out in consultation with Jacton engineers.

How to Correctly Select a Complete Part Number and Place an Order



1. Model Number

- JTD50, Maximum static load capacity 50kN.
- High precision ball screw diameter 40mm, single lead 10mm, custom double lead for higher speed. 
Important Note: Under compression load, long stroke ball screw jack, must check the permissible buckling load. 

2. Jack Configuration and Jack Designs
- US
: Upright mount, Translating Screw Design.
- IS: Inverted mount, Translating Screw Design.
- UR: Upright mount, Rotating Screw Design.
- IR: Inverted mount, Rotating Screw Design.
- UK: Upright mount, Anti-rotation Screw Design.
- IK: Inverted mount, Anti-rotation Screw Design.

Important Note: 
The ball screw of Translating Screw Jack (US or IS) must be attached to the guided load which prevents the ball screw from rotating. To add the linear guides, linear rails or rolls are recommended.
- Important Note: If your application involves a load which is unattached, unguided or the load is free to rotate and not translate, then an Anti-rotation Screw Jack (UK or IK) are required to prevent the ball screw rotation. The anti-rotation device which is supplied with a square nut at the end of ball screw, inside a square rigid protective tube.
- Important Note: Double lead ball screw is not self-locking, will lower under load. Brake motors or external locking systems are recommended. 
- Available in double clevis ball screw jack, and trunnion mounting ball screw jack (pivoting load). 

3. Stroke & 5. Screw End Conditions
- Stroke is travel expressed in millimeter(mm) or inches and not the actual screw length.  
- Standard Screw End Conditions: top plate(load pad), clevis end(male clevis), plain end, threaded end. Also rod end, and fork head(female clevis) are available. Custom screw ends are acceptable.


4. Worm Gear Ratio
- H: High ratio 7:1, one turn of input, travel length 1.43mm
- L: Slow ratio 28:1, one turn of input, travel length 0.36mm
- Customize the worm gear ratios. 

6. Input Shaft Codes and Optional Shaft Codes
- Below pictures with Top View
- A: Single Input, Left Side Shaft.             
- B: Single Input, Right Side Shaft.        
- C: Double Input Shafts
- M1: Left Side Shaft, Right Side Motor Flange (Motor Mounts).                                   
- M2: Right Side Motor Flange (Motor Mounts).   
- M3: Right Side Shaft, Left Side Motor Flange (Motor Mounts).
