About the Airtac SAI80 Standard Air Cylinder SAI80BX35
The AirTAC SAI80X35 is a double-acting ISO 15552 profile cylinder engineered for robust linear motion. Delivering a push force of 2513 N and a pull force of 2268 N at 0.5 MPa, this 80 mm bore unit handles heavy loads with a compact 35 mm stroke.
Built with a SUS304 stainless steel rod for superior corrosion resistance, it features PT tapered port threads and an extruded aluminum barrel. The barrel includes dual sensor grooves, allowing direct mounting of CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX35 Is Used
Heavy-Duty Clamping
Provides 2513 N of clamping force at 0.5 MPa for securing thick metal plates during machining or welding processes.
Short-Stroke Pressing
Ideal for inserting bearings or pins into housings, utilizing the compact 35 mm stroke to deliver high impact force in tight spaces.
Pallet Stopping
Acts as a heavy-duty stopper on assembly lines, using the 80 mm bore strength to halt loaded pallets safely.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX35 the Right Cylinder?
Select this 80 mm bore model when an application requires significantly more thrust than a 63 mm cylinder, which offers 1559 N at 0.5 MPa. The short 35 mm stroke is optimal for high-force clamping or pressing tasks where space is strictly limited.
Because this standard SAI variant relies solely on air pressure, it will drift if supply is lost. For vertical loads requiring fail-safe holding, consider the SAIL locking cylinder or an external pilot-operated check valve. To replace existing hardware, match the 80 mm bore, 35 mm stroke, G3/8 port, and mounting accessories like an FA flange or LB foot.
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 SAI80 Standard Air Cylinder SAI80BX35 FAQ
At an operating pressure of 0.5 MPa, the SAI80X35 generates a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
Yes, the SAI80X35 is dimensionally interchangeable per ISO 15552. It serves as a direct replacement for other ISO 15552 profile cylinders when matching the 80 mm bore, 35 mm stroke, and G3/8 port size.
