Electric linear actuators

You can choose between linear actuators with a push rod and actuators with an open spindle.

The most important facts in brief

Linear actuators are devices that convert linear movements into mechanical force and thus enable precise control of machine components.

They work by converting an energy source, often electrical, into a linear motion that is used for automation applications.

In industry, linear actuators are often used in assembly lines to precisely position and move components.

Technical Drive Elements offers a wide range of linear actuators, including electric linear actuators and other actuators to meet your individual requirements.

Linear actuators with push rod or open spindle

Linear actuators convert a rotary movement into a linear movement. A distinction can be made between linear actuators with a push rod and actuators with an open spindle. The main difference between actuators with an open spindle and actuators with a push rod lies in their design and mode of operation. Both variants offer special advantages. While the stroke of a linear actuator with an open spindle is virtually unlimited, linear actuators with a push rod offer a more compact installation space, as the push rod disappears completely into the actuator.

Decision support for open spindle or push rod

Linear actuators with open spindle consist of a spur gear or worm gear, a permanently mounted DC motor and a trapezoidal threaded spindle. The possibility of replacing the spindle with different lengths offers a high degree of adaptability for different application requirements. Actuators with push rod consist of a fixed gear motor and a rotating spindle, whereby the spindle nut is designed as a push rod.

Differences between the two actuator types:

Design and protection: Actuators with a push rod offer better protection for the spindle thanks to the push tube, while actuators with an open spindle have an exposed spindle.
Adaptability: Actuators with an open spindle offer greater flexibility thanks to interchangeable spindle lengths, while actuators with a push rod offer integrated solutions for specific requirements.
Control options: While both types allow the integration of encoders, actuators with a push rod offer additional space for the installation of limit switches for improved motion control.

The choice between an open stem actuator and a push rod actuator depends on the specific requirements of your application. Open stem linear actuators are compact and offer precise positioning, ideal for applications such as laboratory automation. However, they are more sensitive to environmental influences. Actuators with a push rod, on the other hand, are more robust and designed for higher forces, suitable for industrial applications and mobile machines. They offer increased stability and load capacity, but are larger in size. Your decision should be based on factors such as force requirements, environmental conditions and space available.

Frequently asked questions about linear actuators

What is a linear actuator and how does it work?

An electric linear actuator is a device that converts the rotary motion of an AC or DC motor into a linear motion and can perform both pushing and pulling movements. This movement allows objects to be lifted, dropped, pushed, adjusted, tilted or pulled. Linear actuators offer complete control over motion control, are energy efficient, durable and require little to no maintenance. Compared to hydraulic or pneumatic systems, they are easier to install and take up less space. A linear actuator basically consists of a motor, gears and a lead screw with a drive nut that moves the main rod shaft.

How do stepper motors and encoder technology contribute to the precision and efficiency of linear actuators?

Stepper motors in linear actuators enable high-precision control of movement as they operate in precisely defined steps, which is crucial for applications with high precision requirements. The integration of encoders further enhances this precision by providing continuous feedback on the exact position of the actuator. This combination ensures accurate positioning and motion control, which is essential for many industrial and technical applications where accuracy and reliability are critical.

What are the main differences between electric and hydraulic linear actuators?

Electric linear actuators use electrical energy to generate linear motion and are known for their precision, energy efficiency and ease of control. In contrast, hydraulic actuators use fluid pressure to generate motion and are suitable for applications with higher load requirements. Electric actuators require less maintenance, are more environmentally friendly and easier to integrate into automated systems than hydraulic models.

How do you select the right linear actuator for a specific application?

When selecting a linear actuator, factors such as the required force, the stroke length, the speed, the required positioning accuracy and the ambient conditions should be taken into account. For applications that require precise control, electric linear actuators with stepper motors are ideal. Compatibility with existing control systems and the required service life of the actuator should also be considered. For technical advice, please contact one of our experienced technicians!
