1 ER-SERIES High reduction ratios, without sacrificing efficiency. Compact designs, without requiring special motors. Exceptional shock load capacity, without having to oversize. Greater overhung load capacities, without using expensive special components. The (Servo ER) Circulute is ideal for those applications in heavier industrial environments where a more robust cycloidal gearbox is necessary. The dual pin-housing of the cycloidal provides the ability to preload one wheel against the other reducing the output shaft backlash to less than 6 arc-min. The long output shaft bearing span provides exceptional overhung load capabilities. At 3,000 rpm input the (Servo ER) Circulute can handle motors up to 12 kw and single reduction ratios ranging from 11:1 to 71:1. 408
