About the Airtac SAI63 Standard Cylinder SAI63AX110
The AirTAC SAI63X110 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 110mm stroke. It provides a robust 1559N push force and 1402N pull force at 0.5 MPa, making it well-suited for mid-range industrial actuation tasks. The extruded aluminum barrel design integrates sensor grooves on both sides for straightforward position monitoring.
This specific configuration utilizes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid or mildly chemically washed environments. Fluid supply is routed through PT tapered threads, and the unit includes adjustable air cushions at both ends to absorb impact energy smoothly at operating speeds up to 800 mm/s.

Where the Airtac SAI63 Standard Cylinder SAI63AX110 Is Used
Component Clamping
Secures medium-weight metal workpieces during CNC machining operations using its 1559N push force.
Package Diverting
Actuates sorting arms on packaging lines to redirect heavy boxes with rapid 110mm travel.
Material Pressing
Compresses composite materials in light assembly presses requiring consistent 0.5 MPa actuation.
Is the Airtac SAI63 Standard Cylinder SAI63AX110 the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm variant upgrades your thrust from 982N to 1559N at 0.5 MPa, while stepping down from the 80mm bore avoids the unnecessary bulk of its 2513N push force. The 110mm stroke is optimal for compact machinery layouts requiring moderate travel. For applications needing to maintain a load during air loss, integrate the SAIL locking variant or an external pilot-operated check valve, as standard cushions only decelerate the piston and do not hold position.
When replacing an existing ISO 15552 cylinder, verify the 63mm bore, 110mm stroke, G3/8 PT port, M16x1.5 rod thread, and 36mm cushion length. This unit lacks a magnet (-S not specified), so position sensing via CMSE or DMSE switches is not supported without modification. Mounting can be customized using standard accessories like LB foot brackets or TC trunnion blocks.
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 SAI63AX110 FAQ
At an operating pressure of 0.5 MPa, the SAI63X110 generates a push force of 1559N and a pull force of 1402N. At 0.7 MPa, the push force increases to 2182N.
Yes, the SAI63X110 is dimensionally interchangeable per ISO 15552 standards. Ensure your existing setup matches the G3/8 PT ports and M16x1.5 rod thread for a seamless installation.
