The Festo DSM-B Series Semi-rotary Drive is a high-precision, double-acting rotary vane actuator with metal stops. It is available with a spigot or flanged shaft and with optional tandem rotary vanes. Polyurethane ensures a long service life for the rotary vane and sealing system and precision at the end positions is easily adjusted using the cushioning components. The mechanical gearing between the stop element and the semi-rotary drive prevents movement of the stop system under load.
