Durable cylinders for high forces

• High power density and precision for demanding applications
• Simple engineering and quick commissioning
• Optional oil bath lubrication for continuous load applications
• Sensor package to display lubrication recommendation or oil temperature

Whether it’s pressing, forming or riveting, tensioning, positioning or testing: In industrial production, there are numerous processes in which linear movements with high forces must be performed economically and energy-efficiently. For this purpose, Bosch Rexroth is expanding the electromechanical cylinders in the EMC-HP high-power series to include sizes 190 and 220. Heavy-duty applications with high axial forces of up to 250 kN can be implemented with these sizes in a particularly compact, precise, and dynamic manner – either in direct drive or in parallel using a robust spur gear. An integrated sensor and display package that visualizes either a lubrication recommendation and the oil temperature, depending on the version, ensures maximum productivity. As part of the digital quick selection, an oil bath can now also be selected as a lubrication option for continuous load applications.

The new sizes meet the highest requirements in terms of power density, precision, and dynamics, which are required, among other things, as part of the calendaring process in battery production, in the pressing of wood panels or for sheet metal forming. The EMC-HP portfolio with protection class IP 54 that covers sizes 115 to 220 (housing geometry), now meets the requirements for heavy-duty applications with strokes of up to 1,500 mm in length even more effectively.

The proven PLSA planetary screw assembly installed in the EMC-HP covers dynamic load capacities (Cdyn) of up to 473 kN. The series’ top speed is 0.83 m/s. The new sizes with a robust spur gear ensure optimum power transmission to the screw drive. The new EMC-HP offers additional benefits in terms of durability, maintenance, and efficiency through an integrated sensor package. An optional LED colored strip indicates a re-lubrication recommendation and the oil bath temperature on the basis of the collected operating data.

Simple engineering, quick commissioning

All actuators in various length and mounting options can be selected easily and quickly using the LinSelect e-tool. Complete automation packages including motor, controller, and cables are also available to quickly set up subsystems. A software package (Smart Function Kit) for easy parameterization of the motion task is available on request. After the final online configuration, the individual cylinder or subsystem can be ordered directly from the Rexroth shop.

The preconfigured complete package with parameters stored in the motor memory for the drive controller simplifies and shortens commissioning considerably. The compact design with lightweight aluminum housing and the single-cable solution available for most drives ensure easy integration and quick mounting.
