About the Airtac SAI63 Standard Cylinder SAI63X80S
The AirTAC SAI63X80-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and an 80mm stroke. It provides a robust push force of 1559 N at 0.5 MPa, making it highly suitable for mid-range industrial actuation tasks. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet (-S) for direct compatibility with CMSE and DMSE reed switches. The dual sensor grooves machined into both sides of the barrel allow for highly flexible mounting of position-sensing equipment. Furthermore, the end covers feature adjustable air cushions at both ends, ensuring smooth deceleration of moving loads across its 30-800 mm/s speed range.

Where the Airtac SAI63 Standard Cylinder SAI63X80S Is Used
Mid-Force Clamping
Ideal for holding medium-duty workpieces during machining operations, utilizing its 1559 N push force to secure parts firmly against fixtures.
Package Diverting
Executes rapid 80mm diverting strokes on conveyor lines, with the magnetic piston enabling precise end-of-stroke confirmation via DMSE sensors.
Material Push-Off
Serves as a compact ejector for stamped or molded parts, pushing products out of a press area efficiently within a short cycle time.
Is the Airtac SAI63 Standard Cylinder SAI63X80S the Right Cylinder?
Selecting this 63mm bore over a smaller 50mm option upgrades your thrust from 982 N to 1559 N at 0.5 MPa, whereas stepping up to an 80mm bore would yield 2513 N. The 80mm stroke is ideal for short, rapid movements. Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost; for vertical loads requiring fail-safe holding, consider the SAIL locking variant or an external rod lock. To ensure proper system integration, note that this unit uses a PT tapered G3/8 port and can be mounted using FA/FB flanges or TC trunnions depending on your load orientation.
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 SAI63X80S FAQ
At an operating pressure of 0.5 MPa, the SAI63X80-S generates a push force of 1559 N and a pull force of 1402 N. At the maximum pressure of 1.0 MPa, the theoretical push force reaches 318 kgf.
Yes, the SAI63X80-S is a true ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 compliant cylinders from brands like Festo or SMC, ensuring a direct replacement.
