About the Airtac SAI63 Standard Cylinder SAI63BX275
The AirTAC SAI63X275 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 275mm stroke. It generates a robust 1559 N of push force at 0.5 MPa, making it well-suited for mid-range industrial actuation tasks.
This specific configuration is built with a SUS304 stainless steel rod (material code B) for superior corrosion resistance. It utilizes PT tapered port threads and lacks a magnet, meaning it is optimized for pure pneumatic driving without external sensor tracking requirements.

Where the Airtac SAI63 Standard Cylinder SAI63BX275 Is Used
Parts Ejection
Pushes machined metal components out of a CNC enclosure using the 1559 N push force at 0.5 MPa, with the SUS304 rod resisting coolant mist.
Package Diverting
Actuates a routing arm on a 75mm wide conveyor belt, utilizing the 275mm stroke to fully clear the lane for secondary packaging operations.
Pneumatic Clamping
Secures aluminum extrusion profiles during cutting operations, providing stable clamping force without the need for magnetic position sensing.
Is the Airtac SAI63 Standard Cylinder SAI63BX275 the Right Cylinder?
If your application requires slightly less force, stepping down to a 50mm bore yields 982 N at 0.5 MPa, while an 80mm bore provides 2513 N for heavier loads. Because this 275mm stroke exceeds 300mm when fully extended, long unsupported rods are susceptible to bending under side loads; utilizing an external guide rail or a dedicated guided cylinder will prevent premature rod-bearing wear.
This model serves as a direct replacement for any ISO 15552 cylinder with a 63mm bore, 275mm stroke, PT G3/8 port, and standard mounting accessories. Note that standard SAI cylinders rely on adjustable air cushions to decelerate the piston near stroke ends and will not hold a load if air pressure is lost; for position holding, consider the SAIL lock variant.
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.
