General notes about the series

Repeat accuracy
is defined as a distribution of the end position for 100 consecutive cycles.

Pinion position
is always shown in the left end position. The pinion rotates from here to the right in clockwise direction. The arrow makes the direction of rotation clear.

Torque in the end positions
Please note that the final angular degrees (approx. 2°) before the end position can only be approached using the force of a single drive piston. For this reason, double actuated modules only have about half the rated torque available in this area. An external stop can be used to provide the full torque even in the end positions.

Travel to the pneumatic middle position
is carried out using only half of the nominal torque.

Swiveling time
is the rotation time of pinion/flange around the nominal rotation angle. Valve switching times, hose filling times, or PLC reaction times are not included and are to be considered when cycle times are calculated.

Housing material
Aluminum (extruded profile)

Actuation
pneumatic, with filtered compressed air as per ISO 8573-1:2010 [7:4:4].

Operating principle
Double piston rack and pinion principle

Scope of delivery
Flow control valves, centering bushings, O-rings for direct connection, fitting screws (SRU-plus 63 only), assembly and operating manual with manufacturer’s declaration
