Flexible application: EMC-HD electromechanical heavy-duty cylinder from Rexroth


Ready to install, electromechanical heavy-duty cylinders from Rexroth reduce the design and installation effort

Freely programmable motion sequences, even at high forces

Under harsh environmental conditions, position heavy loads weighing several tons precisely to the micrometre, press powerfully, assemble or close, and vary the motion sequences freely when doing so: The new EMC Heavy Duty (HD) electromechanical cylinders from Rexroth make the benefits of advanced control technology available, even at high forces. The sturdy and ready-to-install units are suitable for machinery and equipment as well as for outdoor use. Users can seamlessly integrate them into intelligent energy management, thus reducing power consumption and CO2 emissions.

Moving heavy loads often requires compromises in the controllability of the axes and results in high construction costs. Machinery manufacturers avoid both disadvantages with the EMC-HD electromechanical cylinders from Rexroth. Force, position and speed can be freely parameterized by the user and flexibly adapted at all times to new tasks via the drive system. Without an additional position sensor, the EMC-HD achieves a repeatability accuracy of up to ± 0.01 mm, and they do so for any number of freely selectable positions within the travel range of up to 1,200 mm.

The electromechanical cylinders for heavy loads transfer the motor movements via ball or planetary screw assemblies, depending on the dynamic and power requirements. The high-precision, backlash-free preloaded Rexroth screw assemblies in various sizes and leads economically cover a wide range of services. Rexroth offers the EMC-HD both as finished, purely mechanical axes as well as a complete system with precisely matched gears, servo motors and controllers from the IndraDrive product line.

For the installation of the heavy-duty cylinders, the user can choose from numerous mounting options. This reduces the construction and assembly work involved. The electromechanical solution does not require any additional components and incorporates space-saving machine designs. The electric start-up is quick and easy, thanks to user-friendly software tools.

Energy-efficient, simple and sturdy

Electromechanical cylinders are extremely energy efficient because they use the energy on demand and implement it with high efficiency in a linear motion. Rexroth IndraDrive servo drives offer numerous opportunities for intelligent energy management. In this way, the drives can regain and store braking energy, along with making it available for other axes of the machine or equipment. As a result, users reduce operating costs over the entire operating life while reducing their CO2 emissions.

The EMC-HD with IP65 protection class are also suitable for outdoor use and operate reliably over a wide temperature range. The simple and sturdy construction ensures a long lifespan, even under harsh environmental conditions. The sealing system protects the cylinder from wear resulting from exterior contamination, thus ensuring long service intervals.
