About the Airtac SAI50 Standard Cylinder SAI50BX375
The AirTAC SAI50X375 is a double-acting ISO 15552 profile cylinder engineered for a 375mm stroke. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for mid-range actuation tasks that require substantial travel distance. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that is dimensionally interchangeable per ISO 15552 standards.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown settings. It utilizes PT tapered port threads and operates without a magnet. If your application requires position sensing, you would need the -S magnet option to mount CMSE or DMSE switches into the dual sensor grooves on the barrel.

Where the Airtac SAI50 Standard Cylinder SAI50BX375 Is Used
Material Transfer Gates
Leverages the 375mm stroke to fully open and close large diverter gates on packaging conveyor lines, utilizing the 982 N push force to move heavy cardboard or plastic components reliably.
Component Forming Press
Provides the necessary 825 N pull force at 0.5 MPa to retract a forming die, while the SUS304 stainless steel rod withstands minor fluid exposure in light-duty metalworking environments.
Pallet Push-Off Station
Acts as a mid-stroke pusher to index empty pallets into a wrapping zone, taking advantage of the ISO 15552 mounting interface to bolt directly onto existing framework.
Is the Airtac SAI50 Standard Cylinder SAI50BX375 the Right Cylinder?
Selecting this 50mm bore over the smaller 40mm bore gives you a significant force upgrade, stepping up from 628 N to 982 N of push force at 0.5 MPa. If your project demands even higher thrust, the 63mm bore offers 1559 N at the same pressure. Because the 375mm stroke creates a long unsupported rod extension, side loads can cause severe bending stress on the rod bearing. To manage this, implement an external guide rail or select a guided cylinder to prevent premature wear and binding.
As a true ISO 15552 cylinder, this model serves as a direct replacement for other ISO 15552 profile cylinders, matching the 50mm bore, 375mm stroke, G1/4 port, and standard mounting accessory footprint (such as LB foot or FA flange). Remember that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not lock the load. If pressure is lost, the rod will drift. For position holding without live air, consider the SAIL lock or BSAI clamp-lock variant.
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 SAI50BX375 FAQ
At a 0.5 MPa operating pressure, the SAI50X375 generates a push force of 982 N and a pull force of 825 N. If you increase the pressure to 0.7 MPa, the push force rises to 1374 N.
Yes. The SAI50X375 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions, 50mm bore, 375mm stroke, and G1/4 port are fully interchangeable with other standard ISO 15552 cylinders.
