Description:
25 ton capacity heavy duty ball screw worm gear jacks lift required input torque to approximately one-third the torque required for the 25 ton machine screw jack. The ball screw sizes 80x16, worm gear ratios 10-2/3:1 and 32:1. Note: without self-locking, require a brake or other external locking device to hold position.  


Main Features
1. Upright or inverted units with maximum static load capacity 25 ton in tension or compression.
2. Required input torque to approximately one-third the torque required for the 25 ton machine screw jack. They also require a brake motor or external locking device to hold position.
3. Ball screw sizes 80mm diameter, lead 16mm (single start ball screw and ball nut).
4. Worm gear set gear ratios 10-2/3:1 and 32:1 ratios.
5. There are no standard travel lengths and each ball screw jack is built to specification. 
6. Standard configurations: upright or inverted 25 ton translating ball screw jacks, upright or inverted 25 ton translating with anti-rotation ball screw jacks, and upright or inverted 25 ton 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 connecting shafts, couplings or 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 25 ton capacity heavy duty ball screw worm gear jacks lift 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 30% running time/30 minutes, 20 °C ambient temperature. 
2. Note: Number of synchronizing jacks which can be connected on the same line is limited by input shaft strength. Refer to the maximum allowable input shaft torque on the above table.
3. Relative humidity: 85% or less (no dew condensation). 
4. Operating ambient atmosphere: Indoor Environment (Indoor room where rain and water cannot enter. Dust volume should be normal).
5. 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

- JTB-25T, Maximum static load capacity 25 tons.
- High precision ball screw diameter 80mm, single lead 16mm, 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
- Stroke is travel expressed in millimeter(mm) or inches and not the actual screw length.  


4. Worm Gear Ratio
- H: High ratio 10-2/3:1, one turn of input, travel length 1.5mm
- L: Slow ratio 32:1, one turn of input, travel length 0.5mm
- Customize the worm gear ratios. 

5. Screw End Conditions
- 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.
