2 SRU-plus Robust. Fast. Hgh Performance. SRU-plus unversal rotary actuator Unversal unt for pneumatc swvel and turnng movements. Feld of applcaton Can be used n ether clean or contamnated areas, anywhere where pneumatc swvelng s requred. Advantages Your benefts Fnely graded seres wth a steady ncrease n torque for multple cases of applcaton, the correct sze as a standard product s avalable Swvel angle can be selected as ether 90 or 180 complete flexblty n selectng the swvel angle; specal angles avalable on request End poston adjustablty +3 /-3 (small) or +3 /-90 (large) can be selected Mddle poston can be selected as pneumatc or locked The locked mddle poston can be unlocked when loaded. The two types of mddle postons always allow further rotaton n ether drecton. Flud feed-through can be used for gases, fluds, and vacuum therefore no nterferng hoses Electrcal rotary feed-through for long-lastng, relable feed-through of sensor, actuator or optonally bus sgnals Choce of electronc magnetc sensors or nductve proxmty sensors for absolute varablty of poston montorng Exchangeable screw-n gude sleeves (bushng) allow for easy mantenance and rapd exchange t after several mllon cycles.

Operatng prncple: Double pston rack and pnon prncple Scope of delvery: Flow control valves, centerng bushngs, O-rngs for drect connecton, fttng screws (SRU-plus 63 only), assembly and operatng manual

4 SRU-plus General notes about the seres Standard condtons: The techncal data shown refers to an envronment of 20 C and atmospherc pressure. Housng materal: Alumnum (extruded profle) Actuaton: pneumatc, wth fltered compressed ar as per ISO :2010 [7:4:4]. Operatng prncple: Double pston rack and pnon prncple Scope of delvery: Flow control valves, centerng bushngs, O-rngs for drect connecton, fttng screws (SRU-plus 63 only), assembly and operatng manual wth manufacturer s declaraton Warranty: 24 months Repeat accuracy: s defned as a dstrbuton of the end poston for 100 consecutve cycles. Pnon poston: s always shown n the left end poston. The pnon rotates from here to the rght n clockwse drecton. The arrow makes the drecton of rotaton clear. Pnon screw connecton dagram: Please note that when the rotatng angle s to be set for less than 90, the left stop wll generally be completely turned n. The left end poston therefore has a screw connecton dagram whch has been rotated by 90 n clockwse drecton n relaton to the drawng, whch s shown at a 180 angle of rotaton. Specal swvel angle: More swvel angles are avalable on request. Torque n the end postons: Please note that the fnal angular degrees (approx. 2 ) before the end poston can only be approached usng the force of a sngle drve pston. For ths reason, double actuated modules only have about half the rated torque avalable n ths area. An external stop can be used to provde the full torque even n the end postons. Travel to the pneumatc mddle poston: s carred out usng only half of the nomnal torque. Cycle tme: s the rotaton tme of pnon / flange around the nomnal rotaton angle. Valve swtchng tmes, hose fllng tmes, or PLC reacton tmes are not a part of ths and are to be consdered when cycle tmes are calculated.

Due to the nnovatve sleeve technology, specal rotaton angles of more than 180 can be provded quckly and economcally. Please contact us for assstance. We are also happy to provde our electrcal feed-throughs wth M5 or M12 connectons on request. On request the electrcal feed-throughs can also be used to transmt bus sgnals. Please note that sutable emergency stop scenaros (e.g. controlled shut down) and restartng scenaros (e.g. pressure buld-up valves, approprate valve swtchng sequences) are needed for all pneumatc actuators. Cuttng off the pressure n an uncontrolled manner could lead to undefned states and behavor. 5
