Types of Electric Pistons
Electric Cylinders
Electric cylinders are devices that create linear motion through electric energy, replacing traditional pneumatic and hydraulic systems. Commonly seen in industries like manufacturing and pharmaceutical packaging, they offer high precision and energy efficiency. Manufacturers like Joyce Dayton and Tolomatic provide a range of electric cylinders suitable for diverse applications.
Electric Pistons
Electric pistons, or electric lift rams, are designed to generate linear force, making them suitable for heavy-duty applications. These pistons are commonly used in automotive and aerospace sectors due to their ability to handle substantial loads with precision. The reliability and performance of electric pistons make them a preferred choice, as evidenced by offerings from Blackhawk Technology Company.
Rod-style and Rodless Actuators
Rod-style actuators have a protruding rod that performs linear movement, ideal for applications requiring high load capacities. In contrast, rodless actuators are designed for applications with space constraints, as they do not have a protruding rod, thus saving valuable space. Both types are utilized in automation and machinery, as highlighted by manufacturers like Parker and Bosch Rexroth.
Micro Linear Actuators
Micro linear actuators are compact devices ideal for applications requiring precise movements in tight spaces. Often found in robotics and medical devices, these actuators provide exceptional control and accuracy. Companies like Actuonix Motion Devices specialize in these miniature solutions, catering to niche markets.
