About the Airtac SAI63 Standard Cylinder SAI63AX800S
The AirTAC SAI63X800-S is a double-acting ISO 15552 profile cylinder engineered for long-distance linear actuation. It delivers a robust 1559 N of push force at 0.5 MPa, making it highly effective for moving substantial loads across its 800 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies the mounting of accessories and sensors.
Equipped with a -S magnet, this unit integrates seamlessly with CMSE and DMSE sensor switches housed in the dual side grooves. For harsh or washdown environments, the piston rod is constructed from SUS420J2 stainless steel (code A), and the standard PT tapered port threads ensure secure, leak-free pneumatic connections.

Where the Airtac SAI63 Standard Cylinder SAI63AX800S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across an 800 mm gap on a production line, utilizing the 1559 N push force at 0.5 MPa to overcome friction.
High-Bay Shuttle Positioning
Actuates shuttle mechanisms in automated storage systems where a long 800 mm extension is required to reach deep storage bins.
Large Door Manipulation
Opens and closes heavy industrial machine guarding or process doors, relying on adjustable air cushions to soften the impact at full extension.
Is the Airtac SAI63 Standard Cylinder SAI63AX800S the Right Cylinder?
Selecting this 63 mm bore cylinder is optimal when an application requires 1559 N of push force at 0.5 MPa but lacks the physical space for a larger 80 mm unit, which offers 2513 N. If your load requirements are lighter, stepping down to a 50 mm bore provides 982 N while conserving air volume.
Because this model features an 800 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external linear guide or use a guided cylinder. Note that the adjustable air cushions at both ends only decelerate the piston near stroke endpoints; they do not lock the load. If pressure drops, the piston will drift, so utilize the SAIL variant or an external pilot-operated check valve for position holding. This unit is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders when matching the 63 mm bore, 800 mm stroke, G3/8 port, and required mounting accessories.
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 SAI63AX800S FAQ
At a 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI63X800-S is built to the ISO 15552 standard, making it dimensionally interchangeable with other ISO 15552 profile cylinders. Ensure your setup matches the 63 mm bore, 800 mm stroke, and G3/8 port configuration.
