About the Airtac SAI63 Standard Cylinder SAI63BX80S
The AirTAC SAI63X80-S is a double-acting ISO 15552 profile cylinder engineered for rigorous automation tasks. Operating at 0.15-1.0 MPa, it generates a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. The 80 mm stroke provides a compact yet powerful extension for mid-range machinery.
This configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a magnetic piston (-S) for seamless integration with CMSE or DMSE position sensors. It utilizes PT tapered port threads and features an extruded aluminum barrel with dual sensor grooves, completely avoiding the bulky tie-rod design of older standards.

Where the Airtac SAI63 Standard Cylinder SAI63BX80S Is Used
Clamping Fixtures
Provides 1559 N of clamping thrust at 0.5 MPa to secure heavy metal components during CNC machining or welding processes.
Package Diverters
Uses the 80 mm stroke to push packages weighing up to 100 kg off a main conveyor line with rapid 30-800 mm/s cycling.
Press Operations
Delivers consistent downward force for light-duty stamping, riveting, or press-fitting bearings into housings.
Is the Airtac SAI63 Standard Cylinder SAI63BX80S the Right Cylinder?
Selecting this 63 mm bore is optimal when a 50 mm bore (982 N push at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (2513 N) would be physically oversized. The 80 mm stroke offers rapid cycling without the space requirements of longer movements. Because this is a standard double-acting cylinder, it relies entirely on continuous air pressure to maintain its position; the integrated air cushions only decelerate the piston at stroke ends and will not hold a load if air pressure drops.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard cylinder matching this bore, stroke, and G3/8 port interface. It supports standard mountings like FA flanges or TC trunnions. For applications requiring secure load holding during pressure loss, consider the SAIL or BSAI locking variants instead.
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 SAI63BX80S FAQ
At 0.5 MPa, this 63 mm bore cylinder provides a push force of 1559 N and a pull force of 1402 N. If operating at 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X80-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the 63 mm bore, 80 mm stroke, and G3/8 port size without modifying the machine frame.
