About the Airtac SAI63 Standard Cylinder SAI63X105S
The AirTAC SAI63X105-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 105mm stroke. It generates 1559N of push force at 0.5MPa, making it well-suited for mid-range industrial actuation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops in seamlessly with other ISO 15552 mounting interfaces.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet for position sensing. The magnet enables direct integration with CMSE and DMSE series switches housed in the dual sensor grooves machined into both sides of the barrel. PT tapered port threads and adjustable air cushions at both stroke ends ensure secure pneumatic connections and controlled deceleration.

Where the Airtac SAI63 Standard Cylinder SAI63X105S Is Used
Component Clamping
Provides reliable 1559N clamping force at 0.5MPa to hold medium-weight machined parts securely during milling or drilling operations.
Package Diversion
Uses the 105mm stroke to rapidly extend a diverter arm on automated packaging lines, efficiently routing boxes at high speeds.
Press Ejection
Delivers consistent push force to eject formed components from light-duty pneumatic presses, improving cycle times.
Is the Airtac SAI63 Standard Cylinder SAI63X105S the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm option upgrades your push force from 982N to 1559N at 0.5MPa, while stepping up to the 80mm bore yields 2513N if your application requires heavier thrust. The 105mm stroke provides a compact extension profile for machinery with limited axial space.
Because the SAI63X105-S is a double-acting cylinder, it relies on continuous air pressure to hold position; exhausting the air or centering the control valve will cause the piston to drift. If your machinery must retain a load safely during pressure loss, consider the AirTAC SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. For direct replacement planning, verify the 63mm bore, 105mm stroke, G3/8 PT ports, and your required mounting accessory type.
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 SAI63X105S FAQ
At a standard operating pressure of 0.5MPa, this 63mm bore cylinder generates 1559N of push force and 1402N of pull force. It can reach up to 2805N push force at 0.9MPa.
Yes, the SAI63X105-S is dimensionally interchangeable per ISO 15552 standards. You can drop it in to replace other ISO 15552 profile cylinders with a 63mm bore, 105mm stroke, and G3/8 port, provided your mounting accessories match.
