The AirTAC Airtac SAI50 Standard Cylinder SAI50BX145 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 145mm 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 SAI50X145 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 982 N at 0.5 MPa. Its 145 mm stroke provides an optimal mid-range extension for automated clamping and material handling tasks.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance in wet or washdown environments. It utilizes PT tapered port threads and includes an integrated sensor groove on both sides of the extruded aluminum barrel for flexible switch placement.

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 982 N of clamping force at 0.5 MPa for securing workpieces during machining or assembly operations.
Offers a fast 145 mm stroke to push cartons or products between conveyor lanes in sorting systems.
The SUS304 stainless steel rod excels in food processing or packaging machinery exposed to moisture.
When sizing this actuator, note that stepping down to a 40 mm bore reduces the 0.5 MPa push force to 628 N, while upgrading to a 63 mm bore increases it to 1559 N. The 145 mm stroke falls below the 300 mm threshold, so severe side-load bending is less of a concern than on long-stroke units, though external guides remain best practice for heavy radial loads.
Because this is a standard double-acting cylinder, it cannot hold a load if air pressure drops entirely; the piston will drift. For position-holding requirements without live pressure, consider the SAIL variant with an air-released lock. As a true ISO 15552 profile cylinder, this 50 mm bore unit with a G1/4 port drops directly into existing ISO 15552 mounting interfaces using standard FA or LB accessories.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder 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 SAI50X145 is a genuine ISO 15552 profile cylinder, making its mounting dimensions fully interchangeable with other ISO 15552 compliant cylinders of the same bore size.
