About the Airtac SAI50 Standard Cylinder SAI50BX270
The AirTAC SAI50X270 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 270mm stroke. It generates a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for medium-duty handling tasks.
Built with a SUS304 stainless steel piston rod, this model provides excellent corrosion resistance for demanding environments. The extruded aluminum barrel utilizes PT tapered port threads and includes sensor grooves on both sides for flexible position detection.

Where the Airtac SAI50 Standard Cylinder SAI50BX270 Is Used
Material Handling
Drives 270mm stroke movements on packaging lines to push or divert medium-weight product cartons efficiently.
Assembly Station Clamping
Provides 982 N of push force at 0.5 MPa to securely hold workpieces during light machining or fastening operations.
Pallet Loading
Extends and retracts to position components or tier layers within automated palletizing cells.
Is the Airtac SAI50 Standard Cylinder SAI50BX270 the Right Cylinder?
If your application requires less force, stepping down to a 40mm bore yields 628 N at 0.5 MPa, whereas upgrading to a 63mm bore provides 1559 N for heavier loads. At 270mm of travel, the unsupported rod is susceptible to bending under side loads, so utilizing an external guide rail or a guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This profile cylinder offers direct dimensional interchangeability with other ISO 15552 components. Note that a plain SAI model cannot hold a load if air pressure is lost; for fail-safe holding, consider the SAIL variant with an air-released lock or the BSAI clamp-lock version.
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.
