The AirTAC SAI50 Standard Cylinder SAI50X300H is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 300mm 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 SAI50X300 is a double-acting ISO 15552 profile cylinder built for rigorous automation tasks. It delivers a push force of 982 N at 0.5 MPa, making it well-suited for medium-duty handling across a 300 mm travel distance. The extruded aluminum barrel omits tie-rods for a clean, modern aesthetic while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
To survive thermally demanding environments, this specific configuration utilizes Viton (FKM) seals instead of standard TPU. This expands the operating temperature range beyond the standard -20 to +70 C, ensuring reliable operation in elevated ambient heat. The standard carbon steel piston rod provides robust resistance against industrial wear and tear.

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 pushing or lifting packages along a 300 mm stroke length on high-speed sorting lines.
Provides consistent 982 N force at 0.5 MPa for seating bearings and pins in automated assembly fixtures.
Handles the indexing and stopping of pallets in hot environments thanks to its high-temp Viton seals.
If your application requires slightly less push force, stepping down to the 40 mm bore yields 628 N at 0.5 MPa. Conversely, moving up to the 63 mm bore provides 1559 N for heavier payloads. Because this model features a 300 mm stroke, side loads can induce significant bending stress on the rod bearing. For optimal longevity, utilize an external guide rail or select a guided cylinder to prevent rod deflection. The PT tapered port thread ensures a tight, leak-free pneumatic connection. Remember that a standard SAI will drift if air pressure is lost; if your process demands fail-safe load holding, consider the SAIL variant with an air-released lock.
Quick checklist
At 0.5 MPa, the push force is 982 N, increasing to 1374 N at 0.7 MPa and 1767 N at 0.9 MPa.
Yes, the SAI50X300 is dimensionally interchangeable per ISO 15552, allowing it to serve as a direct replacement for other standard profile cylinders.
