About the Airtac SAI50 Standard Cylinder SAI50AX220S
The AirTAC SAI50X220-S is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 220mm stroke. It delivers a theoretical push force of 982 N at 0.5 MPa, making it well-suited for medium-duty industrial handling tasks. This specific made-to-order 220mm stroke bridges the gap between standard 200mm and 250mm options, providing exact travel for specialized machine layouts.
This configuration includes a magnet for proximity sensing and is equipped with a SUS420J2 stainless steel rod (option A) for enhanced durability against moisture. The extruded aluminum barrel features sensor grooves on both sides for direct mounting of CMSE or DMSE switches. Fluid ports are PT tapered thread type, and the piston operates at speeds between 30 and 800 mm/s.

Where the Airtac SAI50 Standard Cylinder SAI50AX220S Is Used
Automated Assembly Presses
Provides the 982 N of push force at 0.5 MPa needed for pressing bearings or pins into housings on a high-rate assembly line.
Product Diverters
Uses the 220mm stroke to push items from a main conveyor belt to a secondary packaging lane, with DMSE sensors confirming stroke completion.
Pallet Handling Stops
Acts as a robust pneumatic stop mechanism for medium-weight pallets accumulating before a stretch wrapper or labeling station.
Is the Airtac SAI50 Standard Cylinder SAI50AX220S the Right Cylinder?
Choosing this 50mm bore over the smaller 40mm variant provides a significant force upgrade, jumping from 628 N to 982 N of push force at 0.5 MPa. If your application requires even greater thrust, stepping up to the 63mm bore yields 1559 N at the same pressure. The 220mm stroke is a non-standard, made-to-order length, so verify lead times during your RFQ.
Because this stroke exceeds 300mm? No, at 220mm it is below the threshold where severe rod-bearing bending typically occurs, but side loads should still be minimized. Note that the standard SAI does not hold its position if air pressure drops; the piston will drift. For fail-safe load holding without live pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. As a dimensionally interchangeable ISO 15552 cylinder, it serves as a direct replacement for other ISO 15552 profile cylinders, utilizing a G1/4 port, M16x1.5 rod thread, and standard FA/FB flange or LB foot mounting accessories.

- ✓ 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 SAI50 Standard Cylinder SAI50AX220S FAQ
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. If you increase the operating pressure to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI series is a genuine ISO 15552 (original ISO 6431) profile cylinder. Its standardized mounting interface makes it dimensionally interchangeable with other ISO 15552 cylinders, allowing for a straightforward direct replacement.
