About the Airtac SAI63 Standard Cylinder SAI63X375S
The AirTAC SAI63X375-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 375 mm stroke provides the extended travel needed for material handling and automated positioning tasks. As a genuine AirTAC component, it ensures reliable pneumatic performance.
This variant includes a magnet for CMSE and DMSE sensor switches, fitting neatly into the extruded aluminum barrel's dual grooves. The piston rod utilizes standard carbon steel for high tensile strength, while the PT tapered port thread guarantees a secure, leak-free pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63X375S Is Used
Automated Assembly
Drives 375 mm linear motions to position heavier subassemblies on manufacturing lines.
Material Diverting
Actuates routing gates on conveyor systems where 1559 N of push force is required.
Packaging Pushers
Extends to push cartons or products into secondary packaging machinery.
Is the Airtac SAI63 Standard Cylinder SAI63X375S the Right Cylinder?
Select this 63 mm bore when a 50 mm cylinder's 982 N push force at 0.5 MPa is insufficient, but an 80 mm bore's 2513 N would be excessive. The 375 mm stroke is fully standard for this size, fitting well within the 1500 mm maximum limit.
Because the stroke is 375 mm, the unsupported piston rod is susceptible to bending under side loads. Use external guide rails or a guided cylinder to prevent rod-bearing damage. If the application requires the load to stay put after air pressure drops, pair this cylinder with an external pilot check valve or choose the SAIL locking variant.
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 SAI63X375S FAQ
