Screw Jacks

C-Series

Machine Screw Jack

C-Series cubic screw jack featuring a compact and versatile cubic housing. High reliability and performance are guaranteed with the same precision worm gear set and lead screw as our E-Series screw jack.

The design also include two integrated lubrication systems and over 140 million standard configurations. Capacities range from 10kN to 100kN with machine screw at present.

E-Series

Machine Screw Jack
Ball Screw Jack
Stainless Steel Screw Jack
Roller Screw Jack

Our classic E-Series screw jacks features a precision worm gear set, powerful lead screw, robust housing, two integrated lubrication mechanisms and a comprehensive range of options.

Capacity ranges from 5kN to 2,000kN as standard; as customised design it can be up to 3,500kN. For low duty applications a machine screw jack is generally suitable. For higher duties ball screw jacks or roller screw jacks are available - the roller screw jack is suited to very high loads. Construction of these units is available in standard materials or corrosion resistant eg complete stainless steel jacks. The E-Series screw jacks design is fully customisable by our engineering team to meet your exact application requirements.

S-Series

High Performance Machine Screw Jack

Our high performance series typically has 50% greater duty cycle capabilities than the standard worm gear machine screw jack. So you get more from a machine screw jack before you need to upgrade to a ball screw jack.

Further, the series is engineered to meet the highest standards of durability and possesses a diverse selection of configurations and accessories. Its capacity ranges from 25kN to 200kN as standard.
