The AirTAC Airtac SAI50 Standard Cylinder SAI50BX90 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 interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI50X90 is a double-acting profile cylinder built to strict ISO 15552 dimensional standards, ensuring direct compatibility with other industry-standard actuators. Delivering a push force of 982 N at 0.5 MPa, this 50 mm bore unit is tailored for medium-duty automation tasks.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance in washdown or mildly chemical environments. It utilizes PT tapered port threads and lacks a piston magnet, relying purely on its adjustable air cushions to decelerate the rod at both stroke ends.

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 reliable 982 N clamping force at 0.5 MPa for securing machined metal parts during milling or drilling operations.
Actuates sorting arms on packaging lines with a precise 90 mm stroke to redirect standard cartons efficiently.
Ideal for light press-forming and assembly tasks where a compact 50 mm bore and medium thrust are required.
If your application requires less force, stepping down to a 40 mm bore yields 628 N at 0.5 MPa, whereas upgrading to a 63 mm bore provides 1559 N for heavier payloads. At a 90 mm stroke, side load stress on the rod bearing is minimal, making external guides optional for standard rigid loads.
This model's PT porting and ISO 15552 mounting face make it a direct dimensional replacement for comparable profile cylinders. Because this configuration omits a piston magnet, position sensing is not possible; add the -S option if you require CMSE or DMSE switches. Furthermore, if the machinery loses air pressure, this standard cylinder cannot hold its load and will drift—integrate an external pilot check valve or the SAIL locking variant for fail-safe load holding.
Quick checklist
At a 0.5 MPa operating pressure, the SAI50X90 generates 982 N of push force and 825 N of pull force. Increasing pressure to 0.7 MPa raises the push force to 1374 N.
Yes, the SAI50X90 is a genuine ISO 15552 profile cylinder, making its mounting interface and centering dimensions fully interchangeable with other ISO 15552 compliant actuators on the market.
