About the Airtac SAI40 Standard Air Cylinder SAI40BX220
The AirTAC SAI40X220 is a double-acting ISO 15552 profile cylinder offering 628N of push force and 528N of pull force at 0.5 MPa. This 40mm bore unit with a 220mm stroke is engineered for standardized pneumatic setups requiring reliable linear motion.
Built with an extruded aluminum barrel and a SUS304 stainless steel rod, this variant provides excellent corrosion resistance for demanding environments. It features PT tapered port threads and variable air cushions at both ends to manage piston deceleration smoothly.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX220 Is Used
Package Sorting
Provides robust actuation for diverting heavier packages on logistics conveyor lines with its 628N push force.
Clamping Fixtures
Secures machined parts during CNC operations, utilizing the 220mm stroke to accommodate varying material widths.
Pallet Handling
Drives lifting arms for pallet positioning gates where a compact 40mm bore footprint is required.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX220 the Right Cylinder?
Select this 40mm bore when an application requires more power than a 32mm cylinder (402N at 0.5 MPa) but lacks the space for a 50mm unit (982N at 0.5 MPa). The 220mm stroke provides ample extension for medium-duty handling tasks.
Because the stroke exceeds 300mm, this model requires careful attention to side-load dynamics; long unsupported rods can bend under lateral forces, so utilizing an external guide rail or a guided cylinder is recommended to preserve the rod bearing. If the machinery needs to hold a load vertically without constant air pressure, the standard SAI will drift, so you should specify the SAIL locking variant or an external rod lock. As a dimensionally interchangeable ISO 15552 component, it matches standard 40mm bore, 220mm stroke, PT port, and standard mounting accessory dimensions.
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 SAI40 Standard Air Cylinder SAI40BX220 FAQ
