New Screw Jack Design Guide for automation systems

The new Screw Jack Design Guide from Power Jacks brings together the information needed for designing actuation, lifting and positioning systems using screw jacks. It is packed with information on performance and dimensional details for screw jacks, bevel gearboxes and jacking system components.

Marketing Director Bruce Hamper says: "The design guide shows what a comprehensive portfolio of screw jack automation solutions Power Jacks manufactures and, at 312 pages in size, it is the largest product catalogue Power Jacks have published to date."

The range of screw jacks contained in the design guide is huge, starting at the small 2.5kN capacity units and going all the way up to the large 2000kN units. When used individually or in systems they can actuate, lift or position loads of a few kilograms to thousands of tonnes. As well as screw jacks with cubic and single-face housing styles, the design guide includes details for both translating and rotating machine screw, ball screw and roller screw-driven designs. The range of standard variants helps to solve specific application requirements - including the Anti-Backlash, Anti-Rotation and Safety Nut options for lifting screws. Plus, when it comes to corrosion resistance and harsh environments, there is a comprehensive section on Stainless Steel Screw Jacks.

While most applications can be satisfied with a screw jack design using standard features, options and accessories, some applications need to go further with design specialisation to optimise a given machine or process. As an illustration of what is possible for these types of applications, a sample of special screw jack designs is shown in the design guide. However, there is virtually no limitation to what Power Jacks can do, including completely bespoke designs.

Complementing the screw jacks there are extensive sections for the system components that are regularly used to build jacking systems. These include bevel gearboxes, electric motors, couplings, drive shafts, encoders, limit switches and more.

Bruce Hamper concludes: "For engineers the combination of the Screw Jack Design Guide and Power Jacks' online CAD Portal make an essential toolkit that can allow our customers to quickly and efficiently design screw jack systems that benefit their company."

The Design Guide is available from the brochure download section of the Power Jacks website at in PDF format as a single download or in sections.
