About the Airtac SAI63 Standard Cylinder SAI63X190
The AirTAC SAI63X190 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 1559 N at 0.5 MPa. Its extruded aluminum barrel omits tie-rods, providing a clean profile that drops directly into standardized ISO 15552 mounting interfaces. The 190 mm stroke on this unit is a non-standard, made-to-order length, tailored for specific mid-range travel requirements.
This configuration features a standard carbon steel piston rod and PT tapered port threads. Because a magnet is not specified, it operates without position-sensing capabilities. If your assembly requires end-of-stroke detection, you can specify the -S option to equip dual sensor grooves for CMSE or DMSE switches.

Where the Airtac SAI63 Standard Cylinder SAI63X190 Is Used
Mid-Force Clamping
Secures heavy metal workpieces during CNC machining using its 1559 N push force at 0.5 MPa.
Package Diverting
Actuates routing gates on automated packaging lines with a precise 190 mm travel distance.
Material Ejection
Pushes molded parts out of press dies, utilizing adjustable cushions to soften end-of-stroke impact.
Is the Airtac SAI63 Standard Cylinder SAI63X190 the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm variant significantly increases thrust, stepping up from 982 N to 1559 N at 0.5 MPa. If your application requires less force, stepping down reduces air consumption. Because the 190 mm stroke is custom, ensure your design accommodates the exact extended length.
Remember that a standard SAI cylinder relies entirely on continuous air pressure to hold its load; if pressure drops, the piston will drift. The integrated adjustable air cushions only decelerate the rod near stroke end and do not function as a locking brake. For drop prevention, consider the SAIL variant or an external pilot check valve.
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 SAI63X190 FAQ
At an operating pressure of 0.5 MPa, this 63 mm bore cylinder generates a push force of 1559 N and a pull force of 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X190 is dimensionally interchangeable per ISO 15552. It uses matching mounting accessories like FA flanges or TC trunnions, allowing it to serve as a direct replacement for other standard profile cylinders.
