About the Airtac SAI32 Standard Cylinder SAI32BX270
The AirTAC SAI32X270 is a double-acting ISO 15552 profile cylinder engineered to deliver 402 N of push force at 0.5 MPa. Its 270 mm stroke is well-suited for mid-range linear actuation tasks requiring reliable positioning. Because it adheres to standardized mounting dimensions, it serves as a direct replacement for other ISO 15552 cylinders without requiring bracket modifications.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads, and because it lacks the -S magnet suffix, it does not have integrated sensor grooves for reed switches. The extruded aluminum barrel design eliminates tie-rods, providing a clean exterior that resists debris accumulation.

Where the Airtac SAI32 Standard Cylinder SAI32BX270 Is Used
Package Diverting
Actuates routing gates on packaging lines where 402 N at 0.5 MPa is sufficient to push cartons onto secondary belts.
Small Press Ejection
Ejects lightweight stamped parts from a press bed using a 270 mm stroke, leveraging the SUS304 rod to resist shop-floor coolant mist.
Bin Sorting
Drives sorting paddles in automated distribution centers, utilizing the compact 32 mm ISO 15552 footprint for tight conveyor clearances.
Is the Airtac SAI32 Standard Cylinder SAI32BX270 the Right Cylinder?
Selecting this 32 mm bore is ideal when your application requires roughly 400 N of push force at 0.5 MPa. If your project demands less energy, stepping down is an option, but moving up to a 40 mm bore increases the push force to 628 N at 0.5 MPa. At a 270 mm stroke, the unsupported rod length is moderate, but operators should still ensure axial load alignment to prevent premature rod-bearing wear.
Because this is a standard double-acting cylinder, it will drift if air pressure is lost or exhausted. If your machinery needs to maintain position during an emergency stop or pressure drop, consider the SAIL variant with an air-released lock or integrate an external pilot-operated check valve. To match this exact unit for an ISO 15552 interchange, specify: 32 mm bore, 270 mm stroke, PT G1/8 port, and your preferred mounting accessory like an LB foot or FA flange.
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 SAI32 Standard Cylinder SAI32BX270 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 563 N.
Yes, the SAI32X270 is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders of the same bore and stroke, provided your port and mounting dimensions align.
