About the Airtac SAI63 Standard Cylinder SAI63X180S
The AirTAC SAI63X180-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 180mm stroke. It provides a robust push force of 1559 N and a pull force of 1402 N at 0.5 MPa, making it well-suited for medium-duty industrial handling tasks.
Equipped with a standard magnet (-S), this extruded aluminum barrel unit integrates seamlessly with CMSE and DMSE sensor switches via its dual side grooves. It utilizes a carbon steel piston rod and PT tapered port threads, ensuring reliable sealing and structural integrity for demanding pneumatic setups.

Where the Airtac SAI63 Standard Cylinder SAI63X180S Is Used
Part Ejection
Provides the 1559 N push force needed to reliably eject finished metal parts from machining centers.
Package Diverting
Drives a robust diverter arm on a packaging line, using its 180mm stroke to route heavy cartons.
Clamp Actuation
Actuates heavy-duty clamping fixtures on welding stations, ensuring parts are held securely during processing.
Is the Airtac SAI63 Standard Cylinder SAI63X180S the Right Cylinder?
Choose this 63mm bore when a 50mm bore (982 N push @ 0.5 MPa) lacks the necessary thrust, but you want to avoid the bulk of an 80mm bore (2513 N push @ 0.5 MPa). The 180mm stroke is well within the 1500mm maximum standard stroke, keeping it a readily available standard configuration.
As an ISO 15552 profile cylinder, it serves as a direct dimensional drop-in replacement for other ISO 15552 standard cylinders using the G3/8 PT port, standard M16x1.5 rod thread, and compatible FA, FB, or TC mounting accessories. Note that this standard cylinder relies on continuous air pressure to hold position; it does not feature an internal lock. If your application requires load holding during air loss, consider the SAIL or BSAI variants.
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 SAI63X180S FAQ
At an operating pressure of 0.5 MPa, the SAI63X180-S cylinder delivers a push (extend) force of 1559 N and a pull (retract) force of 1402 N.
Yes, the -S suffix indicates this model includes a standard magnet. It works directly with CMSE and DMSE series sensor switches installed in the extruded aluminum barrel grooves.
