The AirTAC Airtac SAID50 Double Rod Cylinder SAID50AX90 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 90mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAID50X90 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 50 mm bore and 90 mm stroke. Because a rod extends from both end covers, the annulus area is identical on both sides, yielding an equal extend and retract force of 825 N at 0.5 MPa. This symmetric output is ideal for applications requiring consistent push and pull dynamics.
This variant utilizes a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes dual-side sensor grooves for flexible mounting. The rear rod end can drive a secondary mechanism or position flag, while the adjustable air cushions at both ends absorb impact. Note that the through-rod design requires extra rear clearance compared to a single-rod SAI cylinder.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Provides identical 825 N push and pull forces at 0.5 MPa, ensuring perfectly balanced actuation for material handling presses and clamping mechanisms.
The twin-rod design inherently resists torsional rotation, guiding external loads with high precision without needing external guide rails.
Allows a position flag or cam to be mounted on the rear rod end to trigger external sensors, keeping the primary work area unobstructed.
Select this 50 mm bore when an application demands equal 825 N force in both directions, or step down to a 40 mm bore for 528 N if payload requirements are lighter. The double-rod configuration is chosen over a single-rod SAI when twin-station actuation, anti-rotation guidance, or rear-rod sensing is required. It uses a PT tapered port (G1/4) and supports mountings Basic, FA, LB, TC, FTC, TCM1, and TCM2.
This cylinder does not hold its load when air pressure is lost; the piston will drift if the valve is centered or exhausted. For position holding without live pressure, consider a SAIL (air-released lock) or BSAID (clamp-lock) variant. Dimensionally interchangeable per ISO 15552, it serves as a drop-in replacement for other standard double-rod cylinders.
Quick checklist
Because the double-rod design subtracts the rod area on both sides, the extend and retract forces are equal. The SAID50X90 outputs 825 N both ways at 0.5 MPa, and 1154 N both ways at 0.7 MPa.
Yes, the SAID50X90 is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other standard profile double-rod cylinders, utilizing a PT G1/4 port and standard mounting interfaces.
