The AirTAC Airtac SAI50 Standard Cylinder SAI50AX280 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 280mm 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 SAI50X280 is a double-acting ISO 15552 profile cylinder offering a 280 mm stroke. It generates 982 N of push force at 0.5 MPa, making it well-suited for mid-range actuation tasks that require substantial travel distance.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. It utilizes PT tapered port threads and lacks a standard magnet, meaning it is optimized for purely mechanical actuation without internal sensor tracking.

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.
Ideal for actuating diverter arms on packaging lines where the 280 mm stroke provides the necessary reach to redirect goods between adjacent conveyor belts.
Provides reliable horizontal thrust to seat bearings or align sheet metal components within machining centers before final clamping occurs.
Drives the folding mechanisms on automated carton erectors, utilizing its 982 N push force to reliably manipulate heavy cardboard packaging.
If your application requires less force, stepping down to the 40 mm bore yields 628 N at 0.5 MPa, while moving up to the 63 mm bore provides 1559 N. Because this 280 mm stroke creates a long unsupported rod, avoid side-load damage by using an external guide rail or a guided cylinder to prevent rod-bearing bending.
This model uses PT tapered ports and a SUS420J2 rod. As an ISO 15552 profile cylinder, it mounts interchangeably with standard FA/FB flanges or TC trunnions. Remember that the adjustable air cushions only decelerate the piston near stroke ends; they do not hold loads. Use the SAIL variant for secure pneumatic locking when air pressure is lost.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
Yes, as a genuine ISO 15552 profile cylinder, its mounting dimensions and G1/4 port size are fully interchangeable with other ISO 15552 standard cylinders of the same bore size.
