About the Airtac SAI50 Standard Cylinder SAI50BX190
The AirTAC SAI50X190 is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 982 N at 0.5 MPa and a pull force of 825 N. Its 190 mm stroke provides the precise mid-range extension needed for packaging and material handling tasks.
This unit features a SUS304 stainless steel piston rod for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing for easy position monitoring when paired with a magnet-equipped variant.

Where the Airtac SAI50 Standard Cylinder SAI50BX190 Is Used
Packaging Equipment
Drives the folding arms on automated cartoners, utilizing the 982 N push force to cleanly crease heavy cardboard at high cycle rates.
Material Diverters
Actuates routing gates on conveyor lines, where the 190 mm stroke provides the exact reach needed to redirect packages between parallel belts.
Clamping Fixtures
Secures aluminum extrusions during machining operations, taking advantage of the corrosion-resistant SUS304 rod in humid shop environments.
Is the Airtac SAI50 Standard Cylinder SAI50BX190 the Right Cylinder?
Select this 50 mm bore when an application requires stepping up from a 40 mm cylinder, which offers 628 N of push force at 0.5 MPa. If your project demands less force, consider the 32 mm bore option providing 402 N. The 190 mm stroke is well within standard limits, keeping the assembly compact.
As a true ISO 15552 profile cylinder, this model serves as a direct replacement for other standard cylinders with matching 50 mm bore, 190 mm stroke, G1/4 port, and compatible mounting accessories like FA flanges or TC trunnions. Note that a standard double-acting cylinder will drift if air pressure is lost; use an external rod lock or the SAIL variant if the load must be held securely during an outage.
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 SAI50 Standard Cylinder SAI50BX190 FAQ
At an operating pressure of 0.5 MPa, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. If pressure increases to 0.7 MPa, the push force rises to 1374 N.
Yes, it shares the exact ISO 15552 mounting interface dimensions. You can directly swap it with any other ISO 15552 profile cylinder that matches the 50 mm bore, 190 mm stroke, and G1/4 port size.
