Product catalog summary
Introduction
The document discusses the transition from hydraulic to electro-mechanical drives in mechanical engineering and the automotive industry, highlighting energy efficiency, precision, and flexibility as key advantages of electric drives.

Energy Efficiency
Electric drives consume energy only when needed, unlike hydraulic systems that require constant energy availability. This results in significant energy savings, with electric cylinders consuming 600 kWh annually compared to 14,400 kWh for hydraulic cylinders.

Benefits of Electric Clamping Systems
  • Ecological: Energy is used on demand, reducing consumption.
  • Precision: Adjustable stroke and power for sensitive workpieces.
  • Efficiency: Clean, oil-free, and noise-reduced environment.
  • Low Maintenance: No oil changes required, early maintenance detection.
  • Safety: Continuous monitoring ensures reliable processes.

EHS Electrical Cylinder with Through-Hole
Designed for power chucks with through-hole, offering energy efficiency, precision, and low maintenance. Features include a coolant collector and standard spindle fastening.

EVS Electrical Cylinder without Through-Hole
Suitable for power chucks without through-hole, providing similar benefits as the EHS model. It includes a feed-through for coolant or other media.

Technical Specifications
Detailed specifications for both EHS and EVS models are provided, including dimensions, force areas, and speed limits.

Accessories
Various accessories are available, such as servo drives, control units, servo amplifiers, cable sets, brake modules, and resistors, which are necessary for the operation of the electrical cylinders.

e-Cylinder EHS & EVS-2

ELECTRICAL CYLINDER WITH AND WITHOUT THROUGH-HOLE Electric clamping systems are still at the starting point of their development. However, they are becoming increasingly interesting since well-known machine manufacturers already offer highly efficient all-electric machines which are operating without hydraulic and pneumatic systems. With the development of its EHS / EVS electric clamps, RÖHM has made an important contribution to this trend. In the different areas of mechanical engineering and the automotive industry, the trend to replace hydraulic drives by electro-mechanical drives is recognizable....
