Screw Jacks

Our screw jacks come in a variety of series designed to meet the challenges of any application.

They range from the classic single face screw jack, one of the most widely used and popular screw jacks worldwide, proven in the most demanding linear motion applications. To our high performance subsea screw jacks for the ever-growing industrial demands placed upon our products.

Bevel Gearboxes

Transmiting rotary mechanical power through ninety degrees or split power from one input drive to two or three output drives.

Our Bevel Gearboxes use precision-cut spiral bevel gears to deliver a smooth and quiet transmission with an efficiency of up to 98%, delivering high torque ratings and impressive thermal characteristics.

Standard compact designs or customised units meet the most arduous of conditions - whether inside, outside, on land or subsea.

Electric Linear Actuators

Our Electro Mechanical Actuators are designed for low to high duty applications, with loads up to 2000kN.

Our linear actuators deliver powerful, smooth and precise linear motion.

Key Features

  • Standard capacities: 5kN to 2000kN
  • Available in Stainless Steel
  • Machine Screw, Ball Screw & Roller Screw Options
  • And of course, our skilled engineers can always customise a linear actuator design.

Lead Screws

At the heart of our linear motion products is our lead screw technology which has provided our customers with high quality precision products for over 25 years.

Go beyond the performance of ball screw with our highly efficient Spiracon™ planetary roller screw. It is a unique concept, to meet unique needs.

Key Features

  • Standard capacities: 5kN to 1200kN
  • Available in Stainless Steel
  • Machine Screw, Ball Screw & Roller Screw Options

Jacking Systems

Screw jacks can be connected together in systems so that multiple units can be operated and controlled together.

These jacking system arrangements or configurations can be built in many different formats to suit an application. Multiple screw jacks can be linked together mechanically or electrically. The latter is useful if there is no space for linking drive shafts.

System Components

Creating a Power Jacks motorised actuator system requires a range components all of which have been selected to offer the best possible performance with our range of Screw Jacks, Linear Actuators and Gearboxes.

Choose from the range of couplings and drive shafts, motors, reduction gearboxes, plummer blocks and hand wheels, limit switches, sensors and encoders or ask our sales team to help guide you to the product that’s right for your system.

Load Monitoring

A division of Power Jacks devoted to Load Monitoring Solutions. We manufacture a comprehensive range of standard load cell products and also offer a bespoke, custom load cell design service.

In addition to the load cell products we offer a hire, repair and calibration service.
