About the Airtac SAID50 Double Rod Cylinder SAID50AX150
The AirTAC SAID50X150 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50 mm bore and 150 mm stroke. Because a rod exits both end covers, the annulus area is identical on extend and retract, yielding a balanced 825 N force each way at 0.5 MPa. It uses a PT tapered port thread and a durable SUS420J2 stainless steel rod.
This through-rod design allows you to mount the primary workpiece on one end while attaching a position flag, cam, or secondary mechanism to the rear. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable air cushions at both ends absorb kinetic energy near stroke end without acting as a lock.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX150 Is Used
Symmetric Force Transfer
Ideal for moving payloads between two stations where the 825 N push and pull forces must remain perfectly balanced throughout the entire cycle.
Anti-Rotation Slides
The twin-rod architecture prevents piston rotation, providing precise linear guidance for rigid lifting frames and guided presses.
Through-Rod Sensing
Mount the primary tool on the front rod end and attach a rear limit flag to trigger external position sensors.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX150 the Right Cylinder?
Choose this 50 mm bore when an application demands equal push and pull velocity alongside dual-side guidance to prevent rotation. If your mechanism requires less force, stepping down to the 40 mm bore provides 528 N each way at 0.5 MPa. Conversely, scaling up to the 63 mm bore offers 1402 N both directions for heavier transfers.
A plain SAID50X150 will drift if air pressure is lost or the valve is centered; it cannot hold a load mid-stroke. For suspension requirements, specify a SAIL (pneumatic lock) or BSAID (clamp-lock) variant. This cylinder is dimensionally interchangeable per ISO 15552, using the reduced SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) without the FB, CA, CB, or CR options.

- ✓ 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 SAID50AX150 FAQ
The SAID50X150 generates 825 N of force in both the extend and retract directions at 0.5 MPa, increasing to 1154 N at 0.7 MPa. The twin-rod design ensures these figures are identical both ways.
Yes, the SAID50X150 is dimensionally interchangeable with other ISO 15552 profile cylinders. It shares the standard 50 mm bore footprint and uses a G1/4 port, ensuring a direct drop-in replacement.
