About the Airtac SAI80 Standard Air Cylinder SAI80BX55S
The AirTAC SAI80X55-S is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 2513N push force at 0.5 MPa. With its 55mm stroke, it is tailored for short-travel, high-thrust operations in standardized machinery.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for proximity sensing via CMSE or DMSE switches in the dual barrel grooves. It utilizes PT tapered ports and adjustable air cushions at both ends to manage impact deceleration.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX55S Is Used
Heavy Stamping
Provides the 2513N force needed to drive short-stroke stamping and punching operations in automated metal fabrication.
Pallet Stopping
Acts as a robust stopper block for heavy pallets on assembly lines, using the integrated magnet to confirm blocking position.
High-Force Clamping
Secures large workpieces during machining or welding, leveraging the corrosion-resistant SUS304 rod in harsh environments.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX55S the Right Cylinder?
If your application requires less thrust, stepping down to the 63mm bore yields 1559N at 0.5 MPa; conversely, the 100mm bore offers 3927N for heavier loads. Because this is a genuine ISO 15552 profile cylinder, it serves as a direct replacement matching the 80mm bore, 55mm stroke, G3/8 port, and standard mounting accessories like FA flanges or TC trunnions. Note that the adjustable cushion only decelerates the piston near stroke end; it does not hold a load. If pneumatic pressure drops, the rod will drift, requiring an external rod lock or the BSAI clamp-lock variant for secure positioning.
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 SAI80BX55S FAQ
At 0.5 MPa, the SAI80X55-S generates 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
No, the standard SAI cylinder does not lock position under lost air pressure. For holding vertical loads without live pressure, use the SAIL lock variant or an external rod lock.
