About the Airtac SAID50 Double Rod Cylinder SAID50X90S
The AirTAC SAID50X90-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a piston magnet for position sensing. Because a rod extends from both end covers, the annulus area is identical on each side, yielding exactly 825 N of output force in both extend and retract directions at 0.5 MPa. This symmetric force capability makes it ideal for transferring loads without deceleration mismatches.
The rear rod protrusion allows you to mount a cam or position flag directly opposite the primary workload, providing dual-side guidance and superior anti-rotation stability. It features standard carbon steel rods, PT threaded ports sized G1/4, and adjustable air cushions at both ends to absorb kinetic energy near stroke completion.

Where the Airtac SAID50 Double Rod Cylinder SAID50X90S Is Used
Symmetric Force Transfer
Drives a reciprocating shuttle where equal 825 N push and pull forces are critical for maintaining consistent cycle times without speed variations.
Anti-Rotation Slides
The twin-rod geometry prevents piston rotation, guiding a vertical pickup head precisely without needing external linear bearings.
Rear-Sensing Actuation
Mounts the primary work tool on the front rod while utilizing the rear rod extension to trigger a DMSE solid-state sensor flag.
Is the Airtac SAID50 Double Rod Cylinder SAID50X90S the Right Cylinder?
Select this 50 mm bore double-rod actuator when your mechanism requires equal push and pull forces, such as 825 N at 0.5 MPa, alongside inherent anti-rotation resistance. If your application demands less force, the 40 mm bore variant offers 528 N each way, while stepping up to the 63 mm bore provides 1402 N. The twin-rod design is specifically chosen over a single-rod SAI when you need to drive a secondary mechanism or mount a rear sensor flag.
This model includes the -S magnet for use with AirTAC CMSE reed and DMSE electronic solid-state switches. It is dimensionally interchangeable per ISO 15552, utilizing a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) that omits FB, CA, CB, and CR. Note that the adjustable air cushions only decelerate the piston; they do not hold a load. If air pressure is lost, the cylinder will drift, requiring an external pilot-operated check valve or a SAIL lock cylinder for position holding.
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 SAID50X90S FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides. It provides 825 N of force in both the extend and retract directions at 0.5 MPa, and 1154 N at 0.7 MPa.
Yes, the SAID50X90-S is dimensionally interchangeable with other ISO 15552 profile cylinders. It uses PT G1/4 ports and supports standard ISO mounting accessories like FA, LB, and TC brackets.
