About the Airtac SAI63 Standard Cylinder SAI63X185S
The AirTAC SAI63X185-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 185 mm stroke provides the extended reach needed for mid-range automation tasks without consuming excessive machine footprint.
This specific configuration includes a magnetic piston (-S) for seamless integration with CMSE or DMSE reed switches along the dual sensor grooves. It is built with a standard carbon steel piston rod and features PT tapered port threads for secure, leak-free pneumatic connections.

Where the Airtac SAI63 Standard Cylinder SAI63X185S Is Used
Clamping Fixtures
Provides the 1559 N force required to secure heavy metal castings securely during CNC machining operations.
Package Diverters
Uses the 185 mm stroke to push medium-weight cartons off a main conveyor belt into secondary packaging lanes.
Material Ejection
Delivers reliable push force to eject molded components from automated presses onto downstream handling lines.
Is the Airtac SAI63 Standard Cylinder SAI63X185S the Right Cylinder?
Selecting this 63 mm bore is ideal when a 50 mm bore (providing 982 N at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (2513 N) would be physically oversized. The 185 mm stroke falls below the 300 mm threshold, so severe rod-bearing bending is less of a concern, though external guides are still recommended for heavy off-center loads.
Because it is a true ISO 15552 profile barrel design, it serves as a direct replacement for any standard cylinder sharing those exact mounting dimensions. To hold a load safely without live air pressure, pair this cylinder with an external pilot-operated check valve or specify the SAIL lock variant instead.
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 SAI63X185S FAQ
At 0.5 MPa operating pressure, 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 -S suffix indicates a magnetic piston. You can mount CMSE or DMSE switches directly into the sensor grooves on both sides of the extruded aluminum barrel.
