About the Airtac SAID50 Double Rod Cylinder SAID50BX30
The AirTAC SAID50X30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a short 30mm stroke. Because a stainless steel SUS304 rod exits both end covers, the annulus area is identical on both sides. This means the cylinder generates an equal 825N of force in both extend and retract directions at 0.5 MPa.
The twin-rod architecture provides inherent anti-rotation guidance and allows you to mount a primary workpiece on one end while driving a cam or position flag from the rear. It includes adjustable air cushions at both ends and dual sensor grooves for CMSE reed or DMSE electronic switches.

Where the Airtac SAID50 Double Rod Cylinder SAID50BX30 Is Used
Symmetric Force Transfer
Drives a delicate transfer mechanism where equal push and pull momentum is critical to preventing product slippage during high-speed indexing.
Dual-Station Actuation
Mounts a forming tool on the front rod end and a secondary ejector cam on the rear rod end to sequence two operations from one pneumatic motion.
Anti-Rotation Slides
Guides a heavy vertical lift gate without twisting, utilizing the inherent torsional resistance of the twin through-rod design over the 30mm stroke.
Is the Airtac SAID50 Double Rod Cylinder SAID50BX30 the Right Cylinder?
Choose this 50mm bore cylinder when an application demands symmetric force and speed both ways, offering 825N at 0.5 MPa. If your mechanism needs less force, step down to the 40mm bore providing 528N both ways. The PT tapered port and G1/4 interface match standard ISO 15552 dimensions, making it a drop-in replacement for any standard double-rod footprint.
Because the SAID50X30 is double-acting only, it cannot hold a load if air pressure is lost or the valve is centered; the piston will drift. For position holding without live pressure, consider an external pilot-operated check valve or the AirTAC SAIL lock cylinder series.
Quick checklist
- ✓ 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 SAID50BX30 FAQ
The SAID50X30 provides equal force in both directions due to its double-rod design. It outputs 825N at 0.5 MPa, 1154N at 0.7 MPa, and 1484N at 0.9 MPa for both extend and retract strokes.
Yes, the SAID50X30 is dimensionally interchangeable per ISO 15552 profile standards. It uses the same G1/4 port and mounting footprint, serving as a direct drop-in replacement for standard ISO 15552 double-rod cylinders.
