About the Airtac SAI63 Standard Cylinder SAI63X200S
The AirTAC SAI63X200-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 200mm stroke. It delivers a robust 1559N push force at 0.5MPa, making it well-suited for mid-weight industrial positioning tasks. The extruded aluminum barrel omits tie rods for a clean exterior, while the standard carbon steel piston rod ensures high structural strength.
Equipped with a factory-installed magnet (-S), this model supports direct mounting of CMSE or DMSE reed switches in the dual sensor grooves. Fluid supply is routed via a PT tapered G3/8 port, and the adjustable air cushions at both ends are preset to 36mm to absorb kinetic energy smoothly.

Where the Airtac SAI63 Standard Cylinder SAI63X200S Is Used
Component Ejection
Provides 1559N of push force at 0.5MPa to positively eject machined metal parts from a fixture, utilizing the 200mm stroke to clear the work envelope completely.
Pallet Diverter
Actuates a routing flap on a 63mm bore conveyor line to divert heavy pallets, relying on the integrated magnet and DMSE sensors for end-of-stroke confirmation.
Clamp Actuation
Drives a secondary clamping mechanism in an automated assembly press, where the carbon steel rod withstands repeated mechanical stress and the PT G3/8 port ensures rapid fill and exhaust.
Is the Airtac SAI63 Standard Cylinder SAI63X200S the Right Cylinder?
Select this 63mm bore when a 50mm bore (982N push at 0.5MPa) lacks the thrust to move your payload, but an 80mm bore (2513N push at 0.5MPa) would physically overwhelm the assembly and waste compressed air. The 200mm stroke provides ample travel for standard machine ejection and gating functions.
Because the standard SAI63X200-S uses adjustable pneumatic cushioning, it cannot hold a load in place if air pressure drops or the valve is centered. For vertical loads requiring fail-safe holding, specify the SAIL variant with an air-released lock or integrate an external pilot-operated check valve. This unit is dimensionally interchangeable per ISO 15552, offering a direct replacement for other profile cylinders sharing the same mounting interface.
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 SAI63X200S FAQ
At a 0.5MPa operating pressure, this 63mm bore cylinder generates 1559N of push force and 1402N of pull force. If you increase the pressure to 0.7MPa, the push force rises to 2182N.
Yes. The SAI63X200-S is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions and interface are standardized. You can use it as a direct replacement for any other cylinder built to the same ISO 15552 specification, matching the 63mm bore, 200mm stroke, and G3/8 port.
