About the Airtac SAID50 Double Rod Cylinder SAID50X30
The AirTAC SAID50X30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and 30mm stroke. Because a piston rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 825N force in both directions at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This through-rod design allows you to mount the primary workpiece on one end and a secondary cam, position flag, or guide on the rear rod end. The standard carbon steel rod and PT G1/4 tapered port ensure robust performance and reliable pneumatic connection for demanding transfer tasks.

Where the Airtac SAID50 Double Rod Cylinder SAID50X30 Is Used
Symmetric Transfer
Anti-Rotation Guide
Rear-Rod Sensing
Is the Airtac SAID50 Double Rod Cylinder SAID50X30 the Right Cylinder?
Choose this 50mm bore over the smaller 40mm (528N both ways at 0.5 MPa) when your application demands higher symmetric force, or step up to the 63mm bore (1402N) for heavier loads. The twin-rod architecture is selected over a single-rod SAI when superior anti-rotation guidance, dual-side actuation, or rear-rod sensing is required. Note that the adjustable air cushions only decelerate the piston near stroke end; this cylinder will not hold a load if air pressure is lost. For position holding without live pressure, consider an external rod lock or the SAIL series. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement matching standard 50mm bore, 30mm stroke, and G1/4 port dimensions.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID50 Double Rod Cylinder SAID50X30 FAQ
The SAID50X30 delivers an equal force of 825N in both extend and retract directions at 0.5 MPa, because the rod occupies both sides of the piston making the effective area identical.
Yes, as a profile cylinder dimensionally interchangeable per ISO 15552, it serves as a drop-in replacement for other standard 50mm double-rod cylinders with a G1/4 port.
