  • If the mechanical lifting machine jack is loaded in compression. It may be necessary to select a jack with a load greater than the nominal. This is due to the relationship of the diameter to the maximum spindle length. You can consult our engineering for an analysis of the applied force.
  •  As the duty cycles are intermittent, there is an inverse relationship in relation to the maximum duty cycle of the actuators and the load being moved. Please consult our application engineers for assistance in determining the most suitable machine jack.
  • The input RPM must not exceed the value in the table.
  • Never exceed the static and dynamic capacity of the jack.
  • Never exceed the power listed in our specification tables.
  • If the maximum power recommendation is exceeded, reduce the speed or use a larger capacity jack.

Need Help Selecting a Mechanical Screw Jack?

In general, machine screw jacks(also called Acme screw jack, Trapezoidal screw jack) can convert rotary motion into linear motion through the motor. They can be used anywhere to push, pull, tilt, pivot, and lift or lower loads.

The screw jack normally incorporates a ball screw or Trapezoidal screw. When it uses trapezoidal screw/acme screw, it called machine screw jack. When it uses ball screw, it called ball screw jack.

Here is a detailed guide with videos and photos to show you how screw jack works.

This Machine screw jack prices start from less than 100usd.  It depends on your load, stroke, end fitting, screw jack type, or lifting screw type. In general:

  • Large load capacity machine jack prices are higher than small load capacity machine jack.
  • For same load capacity jacks, long-stroke price is higher than short ones.
  • Ball screw jacks is higher than the Trapzidal screw jack.
  • Nut traveling jack prices is higher than screw translating jack.
  • Custom-made screw end is higher than standard screw end.

Please refer to above the LMS Machine Screw Jack Technical Data table. Efficiency % ( H ) means the efficiency for high gear ratio. Efficiency % ( L ) means the efficiency for Low gear ratio.

Yes, this definitely no problem. All external components of our stainless steel machine screw jacks are made from 303 or 304 stainless steel. They are perfect to use in corrosion resistance environments.

My load is very small and I have a space restriction, do you have small machine screw jacks?

Yes, you can get it from LiftingMotion. Our smallest machine screw jack is 0.25T(2.5kn) in cubic design and aluminum housing, you can hold it in your hand.

Please share with us your project details, then we can provide a complete worm screw jack lifting solutions with 3D models.

In general,  machine screw jacks are the ideal choice for low to moderate duty cycles, lower efficiency, slower speed application. It usually holds the position without a brake, so it’s also quite suitable for manual operation. The prices are cost-effective.

While ball screw jacks are ideal for moderate to high duty cycles, higher efficiency, and faster travel speeds application. It’s not self-locking, requires a brake motor to hold the position. Compared with machine screw jacks, the prices are relatively high.

You can trust us on high quality, on-time delivery, controlled costs, and reduced risk.
