About the Airtac SAID50 Double Rod Cylinder SAID50AX90S
The AirTAC SAID50X90-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50 mm bore, 90 mm stroke, and an integrated magnet for position sensing. Because a piston rod exits both end covers, the effective annulus area is identical on extension and retraction, yielding a perfectly symmetrical 825 N output force both ways at 0.5 MPa. This through-rod design excels in applications requiring anti-rotation guidance or dual-side actuation.
Equipped with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance, this model utilizes PT tapered port threads and adjustable air cushions at both ends. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily mount CMSE reed or DMSE solid-state switches along either rod end to track the rear mechanism.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX90S Is Used
Symmetric Force Transfer
Drives a workpiece back and forth with identical 825 N force and speed in both directions, ensuring perfectly balanced timing for automated transfer lines.
Anti-Rotation Slides
The twin-rod design prevents the load from twisting during transit, providing precise linear guidance for material handling and packaging equipment.
Through-Rod Sensing
Mounts a CMSE or DMSE position switch on the rear rod end to track mechanism travel independently from the primary front-mounted tooling.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX90S the Right Cylinder?
Choose this 50 mm bore double-rod cylinder when your mechanism requires equal push and pull forces, or needs to drive a secondary cam and position flag from the rear rod without losing stroke length. If your application demands less force, the 40 mm bore variant provides 528 N both ways at 0.5 MPa; for heavier symmetric loads, the 63 mm bore offers 1402 N. The twin-rod architecture inherently resists torsional rotation better than a single-rod SAI cylinder, though for strokes of 300 mm or more you should still add an external guide to prevent rod-bearing bending under high side loads.
This unit is dimensionally interchangeable per ISO 15552, making it a drop-in replacement for other ISO 15552 double-rod cylinders. It uses the reduced SAID mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets found on single-rod versions. Note that a plain SAID does not hold its position or load when air is lost or the valve is centered; the piston drifts. For fail-safe load holding without live pressure, consider a SAIL (air-released lock) or BSAID (clamp-lock) cylinder.
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 SAID50AX90S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the output force is equal in both directions. It provides 825 N at 0.5 MPa, 1154 N at 0.7 MPa, and 1484 N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552. However, the SAID series uses a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It does not use the FB, CA, CB, or CR brackets found on single-rod variants.
