SRU-plus 20-W-180-3

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.

Pinion screw connection diagram
When setting a swivel angle smaller than 90°, the left end stop must be completely turned in. This means that the left end position has a screw connection diagram on the pinion which is clockwise turned by 90° compared to the main view, which shows a swivel angle of 180°.

Customized angle of rotation
More swivel angles are available on request.

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.

Standard conditions
The technical data shown refers to an environment of 20 °C and atmospheric pressure.

Housing material
Aluminum (extruded profile)

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