About the Airtac SAID50 Double Rod Cylinder SAID50X950
The AirTAC SAID50X950 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50mm bore and a 950mm non-standard stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding a perfectly symmetrical output of 825N at 0.5 MPa for both extension and retraction. The extruded aluminum barrel includes integrated sensor grooves on both sides for flexible mounting of position switches.
This through-rod configuration allows you to attach the primary workpiece to one end while utilizing the rear rod end for a cam, position flag, or secondary mechanism. It features a carbon steel rod and a PT tapered port thread. Note that this 950mm stroke exceeds the 1200mm maximum standard range, making it a made-to-order item requiring extra rear-rod clearance.

Where the Airtac SAID50 Double Rod Cylinder SAID50X950 Is Used
Symmetric Force Transfer
Drives a transfer carriage where the 825N force must remain identical in both directions, ensuring consistent cycle times regardless of travel orientation.
Rear-Rod Position Flagging
Mounts the primary tool on the front rod while the rear rod protrudes to drive a cam or limit flag, allowing external position tracking without front-side interference.
Anti-Rotation Slides
Utilizes the twin-rod geometry to prevent piston rotation during the 950mm travel, maintaining precise alignment for guided linear slides.
Is the Airtac SAID50 Double Rod Cylinder SAID50X950 the Right Cylinder?
Choose this 50mm bore non-standard model when an application demands equal push and pull forces alongside an extended 950mm travel. If your project requires less force, stepping down to the 40mm bore yields 528N both ways at 0.5 MPa; stepping up to the 63mm bore provides 1402N. The double-rod design is selected over a single-rod SAI when dual-side guidance, anti-rotation stability, or rear-rod sensing is mandatory.
Because the 950mm stroke is exceptionally long, the unsupported rod mass increases the risk of side-load bending and premature rod-bearing wear; always pair this cylinder with an external guide rail. As a true ISO 15552 cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod profile cylinders. Mounting options include the reduced SAID set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that a plain SAID does not hold its load when air is exhausted; use a SAIL or BSAID for locking requirements.
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 SAID50X950 FAQ
The SAID50X950 generates 825N of force at 0.5 MPa and 1154N at 0.7 MPa. Because it is a double-rod cylinder, this force is identical in both the extend and retract directions.
Yes, the SAID50X950 is a profile cylinder built to ISO 15552 mounting dimensions, making it a drop-in replacement for other ISO 15552 double-rod cylinders. It uses a PT G1/4 port and omits FB, CA, CB, and CR mounts.
