About the Airtac SAI50 Standard Cylinder SAI50BX220
The AirTAC SAI50X220 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 220 mm stroke provides the extended travel needed for mid-range material handling and indexing tasks.
This specific configuration incorporates a SUS304 stainless steel piston rod for superior corrosion resistance, alongside PT tapered port threads. Because it lacks a built-in magnet, it is optimized for purely mechanical actuation without electronic position sensing.

Where the Airtac SAI50 Standard Cylinder SAI50BX220 Is Used
Package Diverting
Provides the 982 N push force required to deflect heavy cartons on a high-speed sorting conveyor line.
Clamp Actuation
Extends 220 mm to secure large steel workpieces inside an automated machining center prior to welding.
Pallet Stopping
Cycles reliably to halt loaded pallets at a designated inspection station within a distribution hub.
Is the Airtac SAI50 Standard Cylinder SAI50BX220 the Right Cylinder?
Select this 50 mm bore unit when a 40 mm bore falls short on thrust, as the step up from 40 mm yields a significant increase from 628 N to 982 N at 0.5 MPa. Conversely, if your application requires less than 628 N, stepping down to a 40 mm bore will save physical envelope space and air consumption.
With a 220 mm stroke, the unsupported rod length is susceptible to bending under side loads. Implement an external guide rail to absorb lateral forces and prevent premature rod-bearing wear. If your machinery requires the load to stay fixed during a complete loss of air pressure, the standard SAI will drift; utilize the SAIL variant with an air-released lock or an external pilot check valve. As a true ISO 15552 profile cylinder, it drops in seamlessly with matching foot (LB) or flange (FA) mounts.
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 SAI50 Standard Cylinder SAI50BX220 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes. The SAI50X220 is built to the ISO 15552 dimensional standard, meaning its mounting interface and envelope dimensions are fully interchangeable with equivalent ISO 15552 profile cylinders from other manufacturers.
