| 1.1.1. | Screw Jack (Mechanical Actuator) Product Summary | ||||||||||||||||||||||||||||||||||||
| Sym-metric Machine Screw Actuators Cubic style metric actuator designed and manufactured in the UK. This actuator was designed with a higher thermal efficiency than conventional machine screw actuators, allowing higher duties and working temperatures, and improved mounting arrangements e.g. Upright and inverted positions are now incorporated in one model. | |||||||||||||||||||||||||||||||||||||
| Conventional Machine Screw Actuators Probably the most widely used mechanical actuator for intermittent duty cycles as the actuator incorporates a precision worm gear set in a rugged casting delivering positive, precise actuation. Available in a comprehensive range including metric models, imperial models in standard materials or stainless steel models for special environments. | |||||||||||||||||||||||||||||||||||||

| Ball Screw Actuators The ball screw actuator can run at higher duties and speeds than machine screw actuators through the high efficiency of the ball screw and nut. The ball screw also provides longer life at load and requires less power than a machine screw actuator for a specified thrust. The range is available with the same number of metric and imperial variants as the machine screw range. All metric models have a ball nut safety device as standard. A high duty cycle model for continuous operation is also available. | |||||||||||||||||||||||||||||||||||||
| Ball Screw Actuators | |||||||||||||||||||||||||||||||||||||
| Miniature Actuators Designed for applications which call for extremely precise very small adjustments. To achieve their high accuracy they are equipped with anti-backlash nuts as standard to minimise vertical backlash between the lifting screw and worm gear nut. These actuators are available with a corrosion resistant finish or in stainless steel for harsh environments. | |||||||||||||||||||||||||||||||||||||
| Miniature Actuators | |||||||||||||||||||||||||||||||||||||
| Special Actuators Power Jacks design and manufacture special actuators to suit specific customer applications whether this requires modification or addition to a standard product or the design of a completely new actuator. | |||||||||||||||||||||||||||||||||||||
| Special Actuators | |||||||||||||||||||||||||||||||||||||
| Actuators Accessories Power Jacks have a comprehensive range of actuator accessories including power transmissions and motion control systems. A turn key actuation solution can therefore be provided to the customer whether it be for singular or multiple actuator systems. | |||||||||||||||||||||||||||||||||||||
