Electric linear actuators use electricity to generate movement and are therefore a clean alternative to hydraulic systems. A hydraulic circuit, on the other hand, uses fluid to transfer energy and generate movement. In mobile machines, these systems can reliably move very large forces and loads.

Linear actuators and hydraulic circuits in comparison:

• Energy efficiency: Linear actuators convert electrical energy directly into motion, minimizing losses. Hydraulic systems, on the other hand, can suffer heat losses, but score points with their high power density.
• Precision control: Electric linear actuators offer very precise motion control. Hydraulic systems are also controllable, but often require more complex control technology.
• Maintenance and reliability: Linear actuators do not require fluids and need less regular maintenance. Hydraulic systems are more complex, but extremely robust and durable in heavy-duty applications.
• Force and dynamics: This is where hydraulics come into their own. Where loads weighing tons need to be moved or fast, powerful movements need to be achieved, hydraulic systems are often the only option.
• Cost analysis: Electric linear actuators may have higher acquisition costs, but offer lower operating costs due to reduced maintenance requirements. Hydraulic systems are usually cheaper to purchase, but require more maintenance in the long term.
• Environmental friendliness: Electric systems avoid oil and the risk of leaks. However, modern technology is making hydraulic systems increasingly efficient and environmentally friendly.

When it comes to high forces, robustness, and proven technology, classic hydraulic circuits remain unbeatable. Electric linear actuators, on the other hand, score points for efficiency, precision, and ease of maintenance. The choice depends on the specific application—and this is exactly where MRS comes in.
