About the Airtac SAID50 Double Rod Cylinder SAID50AX350
The AirTAC SAID50X350 is a double-acting, double-rod ISO 15552 profile cylinder engineered for symmetrical actuation. Because a rod exits both end covers, the annulus area is identical on each side, yielding equal push and pull forces of 825 N at 0.5 MPa. This through-rod geometry provides superior anti-rotation stability and allows a secondary mechanism or position flag to be driven from the rear.
Configured with SUS420J2 stainless steel rods and PT threaded ports, this 50 mm bore unit operates at speeds of 30-800 mm/s. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. It provides adjustable air cushioning at both ends to decelerate the piston smoothly over its 350 mm travel.

Where the Airtac SAID50 Double Rod Cylinder SAID50AX350 Is Used
Symmetric Force Transfer
Drives a workpiece from one end while the opposing rod moves an identical load, utilizing the equal 825 N annulus force in both directions without speed mismatch.
Anti-Rotation Slides
The twin-rod design prevents piston rotation during the 350 mm travel, ensuring precise linear guidance for material handling slides without external guides.
Through-Rod Sensing
Mounts the primary tool on the front rod while utilizing the rear rod extension to trigger a solid-state DMSE or reed CMSE sensor for precise end-of-stroke confirmation.
Is the Airtac SAID50 Double Rod Cylinder SAID50AX350 the Right Cylinder?
Select this 50 mm double-rod cylinder when your mechanism requires identical extend and retract forces or dual-side guidance. If your application needs less force, the 40 mm bore offers 528 N both ways at 0.5 MPa; for heavier loads, the 63 mm bore provides 1402 N. Unlike a single-rod SAI, the SAID50X350 supports a rear-mounted cam or sensor flag while maintaining a dimensionally interchangeable ISO 15552 mounting footprint.
Because this model features a 350 mm stroke, the extended rod length increases the risk of side-load bending under heavy offset loads; an external guide bearing is recommended to prevent premature seal wear. Note that the adjustable cushions only decelerate the piston near stroke end and do not hold the load if air pressure is lost—use an external pilot-operated check valve for position holding. Replacement specifications require a 50 mm bore, 350 mm stroke, PT ports, and the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

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 SAID50AX350 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers an equal force of 825 N in both extend and retract directions at 0.5 MPa, and 1154 N at 0.7 MPa.
Yes, the SAID50X350 is dimensionally interchangeable per ISO 15552. It shares the standard mounting interface and uses the SAID accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2), making it a drop-in replacement for other ISO 15552 profile cylinders.
