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.
