The Festo DSR Series Semi-rotary Drive is a rotary vane actuator with direct transmission to the drive shaft via a vane. It has a swivel angle that is infinitely adjustable from 0 to 184° (Except for DSRL-10 and 12 which have a swivel angle of 0 to 181°). The adjustable stop system is separate from the vane, so forces are absorbed by the stop blocks. In the end positions, the stops are cushioned with elastic polymer pads. The DSR series is available in 10 to 40mm sizes and with a spigot or hollow flanged shaft. The versions with a hollow flange shaft can convey liquid or gaseous media, or tubing and electric cables.
