The AirTAC SAI50 Standard Cylinder SAI50X900SN is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 900mm 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 SAI50X900-S is a double-acting ISO 15552 profile cylinder engineered for a 50mm bore and a 900mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, placing it in a versatile mid-range thrust class for automated machinery.
This specific configuration incorporates a piston magnet for use with CMSE and DMSE reed switches, utilizing the dual sensor grooves extruded into the aluminum barrel. It is built with standard carbon steel piston rod material and NBR seals, making it a highly reliable choice for general industrial pneumatic applications.

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 products or actuating diverters across wide conveyor belts where a 900mm travel distance is required.
Provides the 982N push force at 0.5 MPa needed to index packages or empty pallets in automated sorting hubs.
Suitable for opening and closing large machine safety doors or guards, using the integrated magnet for position sensing.
If an application requires less thrust, stepping down to a 40mm bore yields 628N of push force at 0.5 MPa, whereas upgrading to a 63mm bore provides 1559N for heavier loads. At a 900mm stroke, the extended rod is highly susceptible to bending under side loads; utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature rod bearing wear.
This SAI50X900-S is dimensionally interchangeable per ISO 15552, featuring a G1/4 PT port, standard 50mm mounting accessories, and an integrated magnet (-S). Note that this cylinder relies on adjustable air cushions to decelerate the piston at stroke ends and will not hold a load if air pressure is lost; for position holding, consider the SAIL or BSAI locking variants.
Quick checklist
At 0.5 MPa, this 50mm bore cylinder provides 982N of push force and 825N of pull force. At 0.7 MPa, the push force increases to 1374N.
Yes, the SAI50X900-S shares the exact ISO 15552 mounting interface and dimensions, making it a direct replacement for other ISO 15552 profile cylinders of the same bore size.
