About the Airtac SAI63 Standard Cylinder SAI63AX375S
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 extended travel for mid-range automation tasks. Built with an extruded aluminum barrel, it omits tie-rods for a clean exterior that resists debris accumulation.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The -S suffix indicates an integrated magnet, allowing seamless operation with CMSE and DMSE reed switches mounted directly into the dual sensor grooves. It also features PT tapered port threads.

Where the Airtac SAI63 Standard Cylinder SAI63AX375S Is Used
Material Diverting
Actuates diverter arms on packaging lines, using the extended 375 mm stroke to push products smoothly into secondary lanes.
Component Seating
Presses bearings or pins into housings on an automated assembly line, leveraging 1559 N of thrust at 0.5 MPa for reliable insertion.
Pallet Handling
Lifts or positions medium-weight pallets and fixtures, where the SUS420J2 rod provides necessary resilience against minor environmental moisture.
Is the Airtac SAI63 Standard Cylinder SAI63AX375S the Right Cylinder?
Providing 1559 N at 0.5 MPa, this 63 mm bore is an optimal step up from the 50 mm bore (982 N) when your application demands more thrust without a significant footprint increase. If your project requires even greater power, stepping up to the 80 mm bore yields 2513 N. The 375 mm stroke classifies as a long stroke, meaning the unsupported rod is susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or utilize a dedicated guided cylinder.
As a dimensionally interchangeable ISO 15552 cylinder, this model serves as a drop-in replacement for other standard profile cylinders with matching 63 mm bore, 375 mm stroke, G3/8 port, and mounting accessories like FA flanges or TC trunnions. Note that standard air cushions only decelerate the piston at stroke end and do not hold loads; if pressure drops, the rod will drift. For dead-load holding, specify the SAIL or BSAI 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 SAI63AX375S FAQ
At a standard operating pressure of 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes. The SAI63X375-S shares the exact ISO 15552 mounting interface and dimensions, making it a drop-in replacement for any standard 63 mm bore cylinder with a 375 mm stroke, G3/8 ports, and matching accessories.
