About the Airtac SAI63 Standard Cylinder SAI63BX190
The AirTAC SAI63X190 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 190mm stroke. It generates a push force of 1559 N at 0.5 MPa, making it well-suited for medium-duty handling and clamping operations. The extruded aluminum barrel design omits tie rods, providing a smooth exterior that resists debris accumulation.
This specific unit is configured with a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It uses PT tapered port threads and lacks a standard magnet. For applications requiring end-of-stroke position detection, the barrel features dual-sided sensor grooves compatible with DMSE switches when a magnet is specified.

Where the Airtac SAI63 Standard Cylinder SAI63BX190 Is Used
Metal Stamping
Provides the 1559 N push force at 0.5 MPa required to actuate light-duty stamping and forming presses.
Package Diverting
The 190mm stroke offers ample travel to push packages between parallel conveyor lines in sorting systems.
Parts Ejection
Ideal for ejecting molded or machined components from machinery, utilizing the corrosion-resistant SUS304 rod.
Is the Airtac SAI63 Standard Cylinder SAI63BX190 the Right Cylinder?
Selecting this 63mm bore over the smaller 50mm option upgrades your push force from 982 N to 1559 N at 0.5 MPa, whereas stepping up to the 80mm bore yields 2513 N. The 190mm stroke is a standard length, so it falls well within the 1500mm maximum limit for this bore size, operating smoothly at speeds of 30-800 mm/s.
Because this is a double-acting cylinder, it relies on continuous air pressure to hold loads; if air is removed or exhausted, the piston will drift. Use an external pilot-operated check valve or the SAIL locking variant for fail-safe position holding. As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard ISO 15552 unit with matching 63mm bore, 190mm stroke, G3/8 port, and standard mounting accessories like FA flanges or TC trunnions.
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 SAI63BX190 FAQ
At an operating pressure of 0.5 MPa, this 63mm bore cylinder provides a push force of 1559 N and a pull force of 1402 N. At 0.7 MPa, the push force increases to 2182 N.
