About the Airtac SAI63 Standard Cylinder SAI63BX800S
The AirTAC SAI63X800-S is a double-acting ISO 15552 profile cylinder engineered for long-trroke linear motion. It generates 1559 N of push force and 1402 N of pull force at 0.5 MPa, making it suitable for moving substantial loads over extended distances. The extruded aluminum barrel design omits tie rods, providing a clean exterior and integrated sensor grooves on both sides.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a magnet for CMSE/DMSE position sensing. PT tapered ports and adjustable air cushions at both ends ensure reliable operation and smooth end-of-stroke deceleration.

Where the Airtac SAI63 Standard Cylinder SAI63BX800S Is Used
Extended Stroke Conveying
Pushing heavy pallets or workpieces across an 800 mm gap in automated packaging and material handling lines.
Large Press Ejection
Ejecting finished parts from large stamping presses where a long reach and 1559 N of force are required.
Automated Warehousing
Actuating long-trroke sorting diverters or pushers in high-throughput distribution centers.
Is the Airtac SAI63 Standard Cylinder SAI63BX800S the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (982 N at 0.5 MPa) lacks the thrust for your application, but an 80 mm bore (2513 N at 0.5 MPa) would be physically oversized. At an 800 mm stroke, the unsupported rod length is highly susceptible to bending under side loads. You must use an external guide rail or a fully guided cylinder to prevent premature rod-bearing wear and piston drift.
As a true ISO 15552 cylinder, it provides a direct mounting interface for standardized foot, flange, and trunnion accessories. Remember that the adjustable air cushions only decelerate the piston near the stroke ends; they do not lock or hold a load. If your machinery requires position holding without continuous air pressure, integrate the SAIL variant or an external rod 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 SAI63BX800S FAQ
