Self-contained actuators
High power density, electric control
Self-contained actuators from Bosch Rexroth are designed to offer maximum added value over the entire life cycle – with their compact design with fully electric control and open interfaces, energy-efficient, quiet operation and long, low-maintenance operating life. Thanks to their encapsulated hydraulic transmission, self-contained actuators are an easy-to-use, robust and long-lasting alternative to electro-mechanical actuators. The previous limits as regards cooling, power density and service life are being redefined.
What are the benefits of self-contained actuators?
Self-contained actuators are highly effective: They combine an electric motor, a pump and a hydraulic cylinder with important control functions and shut-off devices in a compact, hermetically sealed system. As a result of the electro-hydraulic design together with modern converter and control technology, linear movements and forces can be controlled precisely and easily. If no force is required, the motor stands still. Any loads or forces applied are supported by the integrated shut-off valves. The result of this power-ondemand control system: Minimal electricity consumption and, ultimately, lower CO₂ emissions during the entire process. Their many advantages make self-contained actuators ideal not only as a modern substitute for hydraulic cylinders with central power units but also as a long-lasting, low maintenance alternative for electro-mechanical linear direct drives.
