About the Airtac SAI63 Standard Cylinder SAI63X120S
The AirTAC SAI63X120-S is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. Its 120 mm stroke is well-suited for mid-range actuation tasks requiring robust thrust. The extruded aluminum barrel design omits tie rods, providing a smooth exterior that simplifies the mounting of accessories.
This variant includes a built-in magnet (-S) for direct compatibility with CMSE and DMSE sensor switches, which slide into the dual sensor grooves on both sides of the barrel. The standard carbon steel piston rod ensures high structural integrity, while the PT tapered port threads provide a secure, leak-free pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63X120S Is Used
Automated Clamping
Provides 1559 N of push force at 0.5 MPa to secure heavy workpieces during machining or welding operations.
Product Diversion
Uses the 120 mm stroke to push products between parallel conveyor lanes efficiently in packaging lines.
Pallet Lift Stops
Acts as a robust stopper mechanism for light pallets, utilizing its dual air cushions to prevent hard impacts.
Is the Airtac SAI63 Standard Cylinder SAI63X120S the Right Cylinder?
Select this 63 mm bore when an application requires higher thrust than the 50 mm class (982 N at 0.5 MPa) but does not need the bulk of an 80 mm bore (2513 N at 0.5 MPa). The 120 mm stroke offers ample extension for pushing, clamping, or lifting tasks. For positioning feedback, pair the integrated magnet with CMSE or DMSE reed switches.
Because it is a true ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 standard cylinders without altering mounting dimensions. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If the system loses air pressure, the rod will drift. For position holding without live pressure, use the SAIL (air-released lock) or BSAI (clamp-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.
