EC3 Series

The EC3 Series provides robust electric cylinders for moderate to heavy thrust loads. Ball or lead screw types yield quiet operation, low backlash and high accuracy, with a choice 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 minimizes the need for routine maintenance.
