About the Airtac SAI100 Standard Air Cylinder SAI100BX220
The AirTAC SAI100X220 is a double-acting ISO 15552 profile cylinder built around an extruded aluminum barrel. It generates a substantial push force of 3927 N and a pull force of 3681 N at a 0.5 MPa operating pressure. This specific 220 mm stroke configuration is ideal for heavy-duty material handling and high-inertia automation tasks that require significant travel without exceeding standard dimensional limits.
This particular unit is configured with a SUS304 stainless steel piston rod (material code B), providing excellent corrosion resistance for humid or chemically exposed environments. The barrel features integrated sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches when position feedback is required. It utilizes adjustable air cushions at both ends to absorb kinetic energy and protect mechanical components from end-of-stroke impact.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX220 Is Used
Heavy Stamping Ejection
Provides the robust 3927 N push force required to eject heavy stamped metal parts from press dies, utilizing the 220 mm stroke to clear the tooling envelope completely.
Pallet Diversion
Ideal for pushing heavy pallets or totes sideways on a high-speed conveyor line, with the adjustable cushion absorbing the kinetic energy of the shifting load.
Automated Press Clamping
Secures large workpieces inside automated machining cells, leveraging the SUS304 stainless steel rod to resist coolant and cutting fluid corrosion.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX220 the Right Cylinder?
When selecting this cylinder, verify that the 3927 N push force at 0.5 MPa is sufficient for your load. If your application requires less force, stepping down to an 80 mm bore reduces the push force to 2513 N, which may improve cycle times and air consumption. Conversely, moving up to a 125 mm bore yields 6136 N of thrust for heavier payloads.
Because the 220 mm stroke exceeds the 300 mm threshold where side loading becomes a critical concern, ensure your mechanical setup prevents rod deflection. If the load cannot be perfectly aligned, use an external guide rail or a guided cylinder to prevent bending stress on the rod bearing. Note that the standard SAI does not hold position when air pressure is lost; if your machine requires fail-safe load holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. This model is dimensionally interchangeable with other ISO 15552 cylinders, featuring a G1/2 PT port, and supports standard mounting accessories like FA flanges or TC trunnions.

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.
