The double vane style offered on the 90and#176; and 100and#176; rotation allows twice the torque of the single vane. Bearings are used throughout the series to support thrust and radial loads. In addition, rubber bumpers are used internally * making this series highly reliable. Optional auto switches can be moved anywhere along the circumference to allow mounting in a position that is most appropriate for your specifications.
