The Linear Actuators Come In The Following Styles

Captive Shaft

Captive linear actuators offer a short stroke in a compact package where anti-rotation of the shaft is not possible by any other means.

+

Non Captive Linear

The non captive leadscrew travels through the motor giving an extremely short footprint.

As with the captive shaft actuator, conversion of rotary to linear motion takes place within the motor itself by means of the integrated leadscrew and nut, therefore eliminating the use of belts and pulleys, couplings and other mechanical transmission components.

+

External Linear

External linear actuators combine conventional leadscrew and nut technology, with stepper motor technology. The leadscrew forms part of the motor shaft negating the need for a shaft to shaft coupling, thus providing zero transmission error from motor to screw and shortening the overall linear foot print.

Linear Actuators Features

Designed To Perform

Engineered with custom thermoplastics in the rotor drive nut and a stainless steel acme lead screw.  This allows the linear actuator to be quieter, more efficient and more durable than the v-thread and bronze nut configuration commonly used in other linear actuators.

Simple and Compact

Hybrid and Can-Stack linear actuators enable the designer to build the shortest possible linear solution for the given space envelope. These units utilise proprietary motor rotor technology, incorporating a leadscrew nut directly into the motor. With both captive and non-captive designs, the leadscrew is able to pass completely through the centre of motor.

Small, Smooth and Accurate

HaydonKerk linear actuators are available in a variety of styles and sizes. Can-stack linear actuators range from 15mm to 46mm diameter with hybrid linear actuators frame sizes from 21mm to 86mm. With up to 400 full steps per revolution and travel increments as small as 0.003mm/step the hybrid linear actuator performs in all areas.

Long Life

Utilising high performance polymers, motor life is improved more than 10 times over the traditional bronze nut style. Depending on application parameters, units are supplied lubricated for life.
