About the Airtac SAI63 Standard Cylinder SAI63BX220
The AirTAC SAI63X220 is a double-acting ISO 15552 profile cylinder offering 1559 N of push force at 0.5 MPa. Its 220 mm stroke provides the extended travel needed for mid-sized material handling and clamping tasks. The extruded aluminum barrel design eliminates exposed tie rods, ensuring a clean exterior.
This specific configuration features a SUS304 stainless steel piston rod (option B), making it highly suitable for environments where moisture or corrosive elements are present. It utilizes PT tapered port threads and lacks a magnet, meaning it is optimized purely for actuation rather than position sensing.

Where the Airtac SAI63 Standard Cylinder SAI63BX220 Is Used
Corrosive Clamping
Ideal for holding parts in washdown or chemical processing areas thanks to the SUS304 stainless steel rod resisting rust and pitting.
Package Diverter
Provides the 1559 N push force and 220 mm travel needed to reliably redirect heavier totes or pallets on sorting lines.
Gate Actuation
Operates medium-sized machine guarding or flow-control gates where a robust, tie-rod-less profile barrel offers a compact footprint.
Is the Airtac SAI63 Standard Cylinder SAI63BX220 the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm variant (which yields 982 N at 0.5 MPa) gives you roughly 60 percent more thrust for heavier payloads. If your application requires less force, stepping down saves physical space. Because the 220 mm stroke exceeds 300 mm, side load is not a severe issue, but always ensure the rod bearing is not subjected to excessive bending moments by using a guided external carriage for heavy off-center loads.
This model is dimensionally interchangeable per ISO 15552, meaning it serves as a direct replacement for other standard profile cylinders with a 63 mm bore, 220 mm stroke, G3/8 PT port, and standard mounting accessories like FA flanges or TC trunnions. Note that a standard SAI does not hold its position if air pressure is lost; for load-holding requirements, consider the SAIL variant with an air-released lock.
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 SAI63 Standard Cylinder SAI63BX220 FAQ
At 0.5 MPa, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. If operated at 0.7 MPa, the push force increases to 2182 N.
No, the standard SAI cylinder relies on air pressure and will drift if pressure is lost. The adjustable air cushion only decelerates the piston at stroke ends; it does not lock the load. For true load holding, use the SAIL variant.
