About the Airtac SAI63 Standard Cylinder SAI63X330
The AirTAC SAI63X330 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 330mm stroke. It delivers a push force of 1559 N and a pull force of 1402 N at 0.5 MPa, making it well-suited for moderate-to-heavy actuation tasks over an extended distance. The extruded aluminum barrel omits tie rods, presenting a clean exterior that resists operational debris.
This unit incorporates standard carbon steel rod construction and uses PT tapered port threads for a robust pneumatic connection. Because no magnet is specified, it operates without internal sensor tracks; should position detection become necessary, an -S designated variant paired with CMSE or DMSE switches would be required.

Where the Airtac SAI63 Standard Cylinder SAI63X330 Is Used
Material Diversion
Drives long-stroke diverter arms on packaging lines to re-route products into secondary lanes.
Component Ejection
Provides the 1559 N push force needed to eject molded parts from machining centers.
Pallet Lift Gates
Actuates intermediate lifting gates on low-profile pallet conveyors over a 330mm reach.
Is the Airtac SAI63 Standard Cylinder SAI63X330 the Right Cylinder?
Selecting this 63mm bore makes sense when the 50mm class (offering 982 N push at 0.5 MPa) lacks sufficient thrust, but the larger 80mm unit (2513 N at 0.5 MPa) would be physically oversized. At a 330mm stroke, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, utilize an external guide rail or switch to a guided cylinder assembly.
This model is dimensionally interchangeable per ISO 15552, serving as a direct drop-in replacement for other standard profile cylinders. It features G3/8 PT ports, an M16x1.5 rod thread, and is compatible with FA/FB flanges or LB foot mounts. Remember that the adjustable air cushions only decelerate the piston near stroke ends; they do not hold a load if air pressure is lost. For secure position holding, consider the SAIL variant with an air-released lock.
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 SAI63X330 FAQ
At a 0.5 MPa operating pressure, this 63mm bore cylinder generates 1559 N of push force and 1402 N of pull force. If pressure is increased to 0.7 MPa, the push force reaches 2182 N.
Yes. The SAI63X330 adheres strictly to ISO 15552 mounting dimensions, making it dimensionally interchangeable with other standard profile cylinders of the same bore and stroke. You can swap it directly using existing FA flanges or LB foot brackets.
