About the Airtac SAI100 Standard Air Cylinder SAI100BX115
The AirTAC SAI100X115 is a double-acting ISO 15552 profile cylinder built for heavy-duty automation. It delivers a substantial push force of 3927 N at 0.5 MPa, making it well-suited for mid-stroke actuation tasks requiring high thrust. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists mechanical debris.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in harsh environments. It uses PT tapered port threading and lacks a standard magnet; if position sensing is required, a separate sensor-ready variant or external switches must be utilized.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX115 Is Used
Heavy Stamping
Provides the robust 3927 N thrust at 0.5 MPa needed to actuate medium-tonnage stamping and forming presses.
Pallet Diverting
Ideal for pushing heavy loaded pallets across transfer lines where high side-force resistance is mandatory.
Plastic Mold Ejection
Drives ejection mechanisms on large molding machinery, utilizing the 115 mm stroke to clear thick parts safely.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX115 the Right Cylinder?
Select this 100 mm bore when 80 mm (2513 N at 0.5 MPa) lacks the necessary push force for moving heavy payloads. At 115 mm stroke, side-load stress on the rod bearing is minimal, though external guides are always recommended for heavy lateral loads. Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops; for fail-safe holding, consider the SAIL or BSAI locking variants. This unit serves as a direct dimensional drop-in replacement per ISO 15552 mounting interface standards, utilizing a G1/2 port and standard mounting accessories.
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 SAI100 Standard Air Cylinder SAI100BX115 FAQ
At a standard operating pressure of 0.5 MPa, this 100 mm bore cylinder generates a push force of 3927 N. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes. The SAI100X115 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 compliant cylinders from various brands. Simply match the bore, stroke, and G1/2 port size.
