Sample Part Number Of Cubic Ball Screw Jack

1. Jack Series
JTD: JTD series cubic ball screw jack

2. Lifting Capacity
50: maximum static lifting capacity 50kN.
For JTD series cubic ball screw jacks, available static lifting capacities 10 kN to 60 kN.
Before selecting lifting capacities, please check corresponding models technical parameter table.

3. Screw Configurations & Mounting Orientation
US: Upright translating screw              UK: Upright anti-rotate screw               UR: Upright rotating screw
IS: Inverted translating screw               IK: Inverted anti-rotate screw               IR: Inverted rotating screw
* Important Note: The ball screw of a translating screw jack must be attached to the guided load which prevents the ball screw from rotating. To add the linear guides, 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 a anti-rotation ball screw jack(square tube and square nut) are required to prevent lifting screw rotation.


4. Travel Length
900, means exact travel length 900mm. All travel length of JTD series cubic ball screw jacks are customized, the travel length available range from 5mm to 4500mm.


5. Worm Gear Ratio
There are two worm gear ratios for every JTD series cubic ball screw jacks models. please check corresponding models technical parameter table
They are H: high speed and L: slow speed
Customized various of worm gear ratios for JTD series cubic ball screw jacks models.

6. Lifting Screw End Fittings
All JTD series cubic ball screw jacks models lifting screw end fittings includes top plate (I), clevis end (II), plain end(III) and threaded end (IV). Custom made spherical hinge, forked head etc. If special lifting screw end fitting needed, please send us the end fitting drawings, we will process them following the drawings.


7. Input Shaft(Worm) Types and Motor Adapter Types
