Linear actuation is employed everywhere, for packaging, life sciences, transportation, and factory automation jobs. Pneumatic and hydraulic linear actuators operate on pressure differentials; electromechanical actuators are either linear motors or rotary motors driving a screw or belt. The selection and use of these technologies is greatly influenced by the user's technical knowledge, the project's budget, energy sources, and performance tradeoffs.
This hydraulic cylinder features tie-rod construction for extended life
under high working pressures, and pressure-energized For example, pneumatic
actuators don't deliver body seals to prevent leaks.
For example, pneumatic actuators don't deliver high force output, but are
well suited when a cost-effective, easy start-up solution is required.
Hydraulic linear actuators generate a lot of noise and can leak nasty fluid,
but are ideal for high force applications that require precise control.
Electromechanical actuators have high energy requirements and are more
difficult to install and maintain, but are preferred for complex,
multi-axis, motion control applications.
