The AirTAC Airtac SAI50 Standard Cylinder SAI50BX45 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 45mm 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 SAI50X45 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 45mm stroke. It provides a push force of 982 N at 0.5 MPa, making it well-suited for compact clamping and indexing tasks.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. It utilizes PT tapered port threads and does not include a magnet for sensor switches.

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 securing workpieces during machining operations where a short, powerful stroke is required.
Provides reliable actuation for routing small to medium packages on material handling lines.
Operates small access gates and machine guards efficiently in industrial settings.
If your application requires slightly less force, stepping down to a 40mm bore yields 628 N at 0.5 MPa. If you need more power, moving up to a 63mm bore provides 1559 N at 0.5 MPa. Because the 45mm stroke is relatively short, side-load stress on the rod bearing is minimal.
As a standard double-acting cylinder, this model relies on continuous air pressure to maintain its position. If power fails or air is exhausted, the piston will drift. For applications requiring true load holding without live pressure, consider the SAIL variant with an air-released lock. This unit is dimensionally interchangeable per ISO 15552 and uses a G1/4 port.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI50X45 provides a push force of 982 N and a pull force of 825 N. At 0.7 MPa, the push force increases to 1374 N.
Yes, the SAI50X45 is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other standard ISO 15552 cylinders. It uses a G1/4 port and PT thread type.
