High-precision and Low-maintenance Actuator for Heavy Loads

Bosch Rexroth adds EMC-HP series for loads of up to 100 kN to its range of EMCs.

Posted: May 23, 2022

Bosch Rexroth’s new EMC-HPs are currently available in three sizes: 115, 130 and 160 (housing diameter) with protection class IP65.

Bosch Rexroth’s electromechanical cylinders (EMCs) are now available in a high-force, high-precision, low-maintenance version – the EMC-HP. Designed for heavy loads up to 100 kN, the new actuators are robust, compact and low maintenance. Based on the reliable planetary screw drive, users will benefit from impressive continuous power even under harsh conditions. This is thanks to both the new oil-bath lubrication and the optional water cooling directly on the screw itself. As with the other members of the EMC family, a fully digital process, from selection through to ordering, shortens the engineering time.
The new EMC-HPs are currently being launched on the market in three sizes 115, 130 and 160 (housing diameter) with protection class IP65 and are suitable for a range of different heavy-duty applications with strokes of up to 1,500 mm: from pressing, forming and riveting to tensioning, positioning and testing.
Each EMC-HP uses Bosch Rexroth’s tried-and-tested planetary screw assembly (PLSA) in order to be able to meet extremely high standards in terms of control accuracy and dynamics. Thanks to a dynamic load capacity (Cdyn) of up to 189.5 kN, high loads can be quickly and accurately moved as part of an energy-efficient process even in complex motion profiles – with axial forces of up to 100 kN and at speeds of up to 0.83 m/s.
The robust and low-maintenance design of the planetary screw assembly also has a positive impact on lubrication intervals. Additionally, the seals can be replaced in just a few steps if required. Overall, this low maintenance linear motion technology from Bosch Rexroth will help to increase productivity and reduce total costs.
Standard system for a range of different applications
Even the engineering process is a breeze: The simple selection procedure using the LinSelect e-tool and subsequent online configuration including drive, the customized EMC solution can be finalized and ready for ordering in a matter of minutes. Numerous options, such as length and attachment method, open up a wide range of applications.
With their compact dimensions, lightweight aluminum housing and single-cable solutions in connection with most drives, the EMC-HPs can be quickly and easily integrated into machine tools on site. In order to ensure short assembly times, Bosch Rexroth supplies the complete system pre-assembled from a single source – including mechanics, drive and controller as well as global service.
