Bosch Rexroth Adds New Range of Electromechanical Cylinders for Heavy-duty Automation

November 17, 2021 by Stephanie Leonida

Bosch Rexroth announces its new family of compact electromechanical cylinders for heavy-duty applications, the EMC-HP series.

The engineering firm, Bosch Rexroth AG, specializes in manufacturing hydraulics components and systems for machining, engineering, factory automation, and mobile applications. Recently, the company introduced its new electromechanical cylinder series, the EMC-HP (high power). The technology has been designed to be robust, low-maintenance, highly precise, and compact. The EMC-HP is suited to heavy-duty applications (such as those with loads of up to 100 kN).

The most common use for an electromechanical cylinder is to drive a piston. The piston, in turn, moves fluid or gas, which can be used in various ways. Electromechanical cylinders are most commonly used in hydraulic and pneumatic systems. They can also be found in other applications, such as controlling valves for steam engines, cranes, and elevators.


Durability and Control

The new EMC-HP series comes in different sizes depending on the housing diameter and an ingress protection (IP) rating of IP54. This means that the product is enclosed in such a way that prevents the ingress of dust that could stop its proper functioning, and it protects against solid objects or splashing water from any angle. 

Temperature control can be employed by spindle cooling and oil-bath lubrication to help prolong the EMC-HP’s durability, meaning the product can operate for longer with continuous power. 

The presence of a planetary screw assembly (PLSA) precision planetary screw drive allows for the conversion of rotary motion into linear motion and vice versa. This enables customers to reach high standards concerning control accuracy and dynamics.

The EMC-HP incorporates a dynamic load capacity (Cdyn) of up to 189.5 kN, which helps move high loads as efficiently as possible. Technical specifications of the EMC-HP include a maximum axial force of 44 to 100 kN, a maximum travel speed of 0.52 to 0.83 m/s, and a maximum stroke of 1,200 to 1,500 mm.


Application Flexibility

With Bosch Rexroth’s LinSelect selection and sizing tool, the EMC-HP can be configured into a tailored EMC solution for various applications. The length and attachment method can be modified for this purpose. Applications for the EMC-HP include pressing, pressing fitting, crimping, deep drawing, bending, embossing, folding, sawing, punching, riveting, clinching, positioning, tensioning, lifting, straightening, and spring testing. 

The new technology has been designed to allow for simplified integration into onsite machine tools. This integration capability, coupled with the supply of the EMC-HP system, preassembled by Bosch Rexroth, enables customers to cut assembly times and maintain uptime.

Overall, Bosch Rexroth’s new EMC-HP was designed to provide greater efficiency and longevity (through low maintenance). The reduced need for maintenance can help customers reduce costs, and application flexibility provides more diversified operations.
