About the Airtac SAI63 Standard Cylinder SAI63AX195S
The AirTAC SAI63X195-S is a double-acting ISO 15552 profile cylinder engineered for standardized mounting interchangeability. Delivering 1559 N of push force at 0.5 MPa, this 63 mm bore unit is tailored for medium-duty automation tasks requiring a 195 mm stroke. Its extruded aluminum barrel omits tie rods for a clean exterior, while the integrated -S magnet enables direct mounting of CMSE or DMSE position switches.
Beyond the standard spec table, this specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to manage kinetic energy at stroke limits. As a genuine AirTAC component, it guarantees reliable, drop-in compatible performance for your pneumatic infrastructure.

Where the Airtac SAI63 Standard Cylinder SAI63AX195S Is Used
Parts Ejection
Provides robust 1559 N push force at 0.5 MPa to reliably eject molded parts or machined components from fixtures.
Package Diverting
The 195 mm stroke and integrated magnet allow precise actuation of sorting gates on high-speed packaging conveyors.
Material Bending
Exerts controlled clamping and bending pressure on light-gauge sheet metal within automated fabrication cells.
Is the Airtac SAI63 Standard Cylinder SAI63AX195S the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm variant provides a significant force upgrade, jumping from 982 N to 1559 N of push force at 0.5 MPa. If your application requires less energy, stepping down to the 50 mm bore optimizes air consumption. The 195 mm stroke offers ample extension for packaging and material handling, while the adjustable cushioning ensures smooth end-of-stroke deceleration.
Because this is a double-acting cylinder, it relies on continuous air pressure to maintain its position. If your system loses pressure or the control valve centers, the piston will drift and drop its load. For vertical or suspended loads requiring fail-safe holding without live pressure, specify the SAIL (air-released lock) variant or pair the cylinder with an external pilot-operated check valve. The -S magnet allows seamless integration with CMSE/DMSE sensors for end-of-stroke confirmation.
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.
