Electric Cylinders - EC2 Large

EC2 Series

The EC2 Series offers an economical solution for light to moderate 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.
