About the Airtac SAI50 Standard Cylinder SAI50BX750S
The AirTAC SAI50X750-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 750 mm stroke makes it well-suited for extended linear travel in automated material handling. The extruded aluminum barrel design omits tie rods, providing a smooth exterior that resists debris accumulation.
This specific configuration includes a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. It is built with a PT tapered port thread and includes a magnetic piston (-S) for seamless integration with CMSE or DMSE position sensors.

Where the Airtac SAI50 Standard Cylinder SAI50BX750S Is Used
Extended Transfer Lines
Drives long-travel pushers on conveyor systems where a 982 N output at 0.5 MPa easily shifts packaged goods between processing zones.
High-Bay Extraction
Ideal for automated storage retrieval arms requiring a 750 mm reach, utilizing the -S magnet for precise end-of-stroke confirmation.
Washdown Sorting
The SUS304 rod provides essential corrosion resistance for diverting flows in food or beverage lines exposed to frequent cleaning cycles.
Is the Airtac SAI50 Standard Cylinder SAI50BX750S the Right Cylinder?
With a 750 mm stroke, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, pair this cylinder with an external guide rail or specify a fully guided cylinder actuator. If your mechanism must hold a load statically without continuous air pressure, note that the standard SAI air cushions only decelerate motion at stroke ends and will not lock the piston; you should specify an external pilot-operated check valve or the SAIL locking variant instead.
This SAI50X750-S offers a true ISO 15552 mounting interface, meaning it is dimensionally interchangeable with other ISO 15552 profile cylinders of the same 50 mm bore and 750 mm stroke. When replacing, verify the PT port, your specific mounting accessory (such as an FA flange or TC trunnion), and ensure the magnet is required for your sensor setup.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI50 Standard Cylinder SAI50BX750S FAQ
At 0.5 MPa operating pressure, 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 are standardized. It serves as a direct replacement for other ISO 15552 cylinders with a 50 mm bore and 750 mm stroke, provided your setup matches the PT port thread.
