About the Airtac SAI63 Standard Cylinder SAI63X190S
The AirTAC SAI63X190-S is a double-acting ISO 15552 profile cylinder engineered for standardized pneumatic automation. Delivering a push force of 1559 N at 0.5 MPa, this 63mm bore unit is built around a tie-rod-less extruded aluminum barrel. The 190mm stroke is well-suited for mid-length actuation tasks requiring consistent kinetic energy absorption.
This variant includes a built-in magnet (-S) enabling direct mounting of CMSE or DMSE magnetic switches along the integrated sensor grooves on both sides of the barrel. It features a standard carbon steel piston rod and PT tapered port threading, ensuring robust performance in demanding industrial environments.

Where the Airtac SAI63 Standard Cylinder SAI63X190S Is Used
Automated Clamping
Provides 1559 N of push force at 0.5 MPa for securing heavy metal components during CNC machining or welding operations.
Material Diverting
The 190mm stroke offers the exact reach needed to actuate diverter arms on mid-sized packaging conveyor lines.
Press Operations
Ideal for light-duty pneumatic pressing and stamping tasks where a consistent 63mm bore output is required.
Is the Airtac SAI63 Standard Cylinder SAI63X190S the Right Cylinder?
Choose this 63mm bore when a 50mm bore (982 N at 0.5 MPa) lacks the necessary thrust, but an 80mm bore (2513 N at 0.5 MPa) would be physically oversized and consume excess air. At a 190mm stroke, the rod bearing experiences moderate loads, but always ensure external guides are used if the application introduces lateral forces.
Being dimensionally interchangeable per ISO 15552, this cylinder serves as a seamless direct replacement for other ISO 15552 profile cylinders. It utilizes a G3/8 port, M16x1.5 rod thread, and can be paired with FA/FB flanges or TC trunnion mounts. If the machinery requires the load to be physically held in place without continuous air pressure, specify the SAIL locking variant instead of relying on the standard air cushions.
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 SAI63X190S FAQ
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. If operating at 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X190-S is dimensionally interchangeable per ISO 15552, meaning it shares identical mounting footprint and center distances with other standard profile cylinders of the same bore size.
