About the Airtac SAI80 Standard Air Cylinder SAI80BX210
The AirTAC SAI80X210 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 2513N push force at 0.5 MPa. Its 210mm stroke is well-suited for medium-to-heavy material handling tasks. Built to the ISO 15552 mounting interface, it provides a dimensionally direct replacement for other standard profile cylinders.
This specific configuration incorporates 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 lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX210 Is Used
Pallet Diversion
Provides the necessary push force to redirect heavy loaded pallets onto secondary conveyor lines without skipping a beat.
Vertical Lift Gate
Actuates heavy security gates or industrial safety barriers where sustained 2513N thrust at 0.5 MPa is required for smooth operation.
Part Ejection
Ejects dense molded components from press beds, utilizing the adjustable air cushions to decelerate the stroke smoothly and reduce noise.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX210 the Right Cylinder?
Select this 80mm bore when an application requires substantially more thrust than a 63mm cylinder (which provides 1559N at 0.5 MPa) but without the physical bulk of a 100mm unit. Because the 210mm stroke exceeds 300mm, it does not mandate external guiding, though side loads should still be minimized to protect the rod bearing.
If the machinery loses air pressure, this standard SAI cylinder cannot hold its load in place and will drift. For gravity-loaded vertical axes requiring safety locking, specify the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder. To match this ISO 15552 footprint exactly, use a PT G3/8 port, pair it with an FA flange or TC trunnion accessory, and note that a magnet (-S) is absent on this unit.
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 SAI80BX210 FAQ
At 0.5 MPa operating pressure, this cylinder generates 2513N of push force and 2268N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 3518N.
Yes, the SAI80X210 is a true ISO 15552 profile cylinder, making its mounting dimensions fully interchangeable with comparable ISO 15552 cylinders from other manufacturers. It is not a tie-rod design.
