How to Choose a Linear Actuator?

You can save over 30% on costs while still improving the technology of your linear assembly at the same time.

Screw-driven or belt-driven linear actuator?

Linear actuators are an important element in automation and mechanical engineering and help with a variety of tasks, from simple to extremely complex ones. Picking the right one is very important, since linear actuators and linear slides can be driven in a wide variety of ways.

Lead screw-driven actuators—for high accuracy

If a lower speed, yet a high level of accuracy, is required, linear actuators with trapezoidal threads are usually a good option. The linear axes with lead screw drives are also great options for high axial thrust forces. Due to the critical speed limit for lead screws, the travel path (max. 1,500 mm/5 feet), the speed, and thus the speed of the lead screw, are severely limited. The recommended speed limit depends on the lead screw diameter.

When should I choose a lead screw-driven linear actuator?

For format adjustments

In extreme environments (heat, cold)

When corrosion resistance is required

When it needs to be low-noise

For shorter travels up to 1.5 meters or 5 feet

For low to medium speed with high accuracy

Belt-driven linear actuators—when things have to go fast

Belt drive linear actuators are particularly suitable for fast positioning and handling tasks. Long travels up to 3,000mm/9.8ft at high speeds are ideal requirements for this linear actuator.

When do I choose a belt-driven linear actuator?

When high speeds are required

For travels up to 3 meters/9.8 feet

If the structure should be particularly flat

If positioning accuracy may be > 0.1mm
