About the Airtac SAI80 Standard Air Cylinder SAI80BX220
The AirTAC SAI80X220 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 2513 N and a pull force of 2268 N at 0.5 MPa. The 220 mm stroke is ideal for mid-range linear actuation tasks requiring substantial reach and power.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. It utilizes a PT tapered port thread and lacks a standard magnet. As a genuine ISO 15552 profile barrel design, it ensures seamless dimensional interchangeability with comparable global standard cylinders.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX220 Is Used
Heavy-Duty Pressing
Applies 2513 N of push force at 0.5 MPa for seating bearings, stamping light components, or forming materials in automated cells.
Pallet Diversion
Utilizes the 220 mm stroke to push heavy pallets off a main conveyor line onto branching spur rollers reliably.
Clamp and Hold
Secures large workpieces during machining or welding operations, taking advantage of the 80 mm bore's rigid profile barrel structure.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX220 the Right Cylinder?
Select this 80 mm bore when an application demands more thrust than a 63 mm cylinder can provide, which typically yields 1559 N of push force at 0.5 MPa. The 220 mm stroke offers extended travel without requiring a custom order. For operations needing exact position feedback, a version with a magnet (-S) is required to mount CMSE or DMSE sensors in the dual barrel grooves.
Because the 220 mm stroke exceeds the 300 mm threshold where side-load risks sharply increase, standard rod bearing wear is less critical here, but external guides should still be considered if the load is not perfectly axial. Note that this standard cylinder relies on air pressure to maintain its position; if pneumatic supply is lost, the load will drift. For fail-safe holding, integrate an external pilot check valve or specify the SAIL or BSAI locking variant.
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 SAI80BX220 FAQ
At an operating pressure of 0.5 MPa, this 80 mm bore cylinder 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 SAI80X220 is built to the ISO 15552 dimensional standard, making it a direct replacement for other ISO 15552 profile cylinders. It shares standard mounting interfaces and uses a G3/8 port.
