Power Jacks Launches New 10kN Screw Jack Giving Improved Possibilities for Machine Building

Power Jacks has announced the official launch of its new 10kN E-series Screw Jack designed to give engineers more capabilities and versatility in actuation, lifting and positioning solutions for machine building.

“The E-Series Screw Jack Range is well established, yet through innovative design we are still finding ways to improve the range to benefit our customers” said Alex Crossland, managing director.

“This new 10kN screw jack is part of our continuously product development plans to deliver new and improved levels of linear motion solutions.”

Key features of the new 10kN Machine Screw Jack include:

1) Easily Integrate Motor Drives & Feedback Devices
Bolt-on mounting points on each side of the gearbox housing where the worm shaft is located allows for the direct mounting of electric motors, motion feedback devices (e.g. rotary cam limit switches and encoders), brakes and other accessories.

2) Strong 4 Bolt Mounting for Screw Jack Base
Secure 4-point mounting method for fixing the screw jack base to a superstructure.

3) High Strength to Weight Ratio
The weight of the screw jacks gearbox has been minimized by making the housing from a high strength yet lightweight aluminum alloy and by using sealed worm shaft bearings to remove the need for a cover flange at each worm shaft end.

4) Integrated Guide Bush for Lifting Screw
The gearbox as standard has an integrated self-lubricated guide bush for precision alignment of the lifting screw.

This new 10kN E-Series Machine screw Jack was developed from customer requirements prioritizing versatility in mounting accessories for drive and feedback devices over the need for an Ultra-Compact gearbox as provided by the original 10kN screw jack. The new design still minimizes size and weight through an optimized design. Both the original design, designated type-1 and the new screw jack, designated type-2, are available giving engineers the choice to pick the best solution for their application.

The E-Series screw jacks are a popular range for customers with millions in service worldwide in a diverse range of industries including Renewable Energy, Food & Beverage, Aerospace, Metal Processing, Construction, Chemical Processing, Paper, Glass, Defense, Nuclear Power, Oil & Gas, and Communications. The success of these products are their performance and versatility in customized design solutions. The new 10kN screw jack follows that ethos and extends the capabilities of the range to further benefit machinery designers.

At launch the 10kN Screw Jack is available in four standard configurations and six standard variants.

Configurations:
1) Translating Screw, Upright
2) Translating Screw, Inverted
3) Rotating Screw, Upright
4) Rotating Screw, Inverted

Variants:
1) Anti-Backlash
2) Anti-Rotation
3) Safety Nut
4) Double Hub Nut
5) Second Guide
6) Double Clevis

The new screw jack also benefits from Power Jacks extensive modular building system for screw jacks allowing extensive customization. Examples of some assemblies featuring “bolt-on” accessories are shown below.

In addition to the standard range customized and bespoke designs of the 10kN E-Series Machine Screw Jack are also available.

The new 10kN E-Series Machine Screw Jack is now available from Power Jacks global sales network.
