Electric Cylinders EC4 Series

Electric Cylinders EC4 Series

The EC4 Series provides robust electric cylinders for heavy-duty thrust loads. Precision-rolled ball screw types yield quiet operation, low backlash and high accuracy, with a selection of motor-to-screw reduction types. Exceptionally durable bearing and drive housings are available with optional environmental features to resist moisture and contaminants. The special design of these cylinders minimizes the need for routine maintenance.
