About the Airtac SAI63 Standard Cylinder SAI63BX195S
The AirTAC SAI63X195-S is a double-acting ISO 15552 profile cylinder offering a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. The 195 mm stroke provides exact motion control for mid-range automation tasks. As a genuine AirTAC component, it ensures reliable performance in demanding environments.
This variant features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. It includes a built-in magnet (-S) compatible with CMSE and DMSE sensor switches, which mount directly into the dual extruded grooves on the aluminum barrel. The PT tapered port threads guarantee a tight, leak-free pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63BX195S Is Used
Stainless Rod Clamping
The SUS304 rod resists moisture and washdowns, making it suitable for packaging machines that require strict hygiene and moderate clamping force.
Intermediate Stroke Diverting
Its 195 mm stroke allows precise actuation of diverters on conveyor lines where a 150 mm stroke falls short but 200 mm would overflow.
Sensor-Ready Assembly
The integrated magnet and dual sensor grooves allow easy mounting of DMSE switches for end-of-stroke confirmation in automated assembly.
Is the Airtac SAI63 Standard Cylinder SAI63BX195S the Right Cylinder?
Selecting this 63 mm bore is ideal when 50 mm (982 N push @0.5 MPa) is too weak, but 80 mm (2513 N push @0.5 MPa) would physically overpower the assembly. The 195 mm stroke is a non-standard incremental length, useful for applications requiring a specific intermediate travel distance rather than the typical 200 mm increment.
Because this is a standard double-acting cylinder, it cannot hold a load in place if air pressure drops or the valve is centered; the piston will drift. For vertical loads requiring fail-safe holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. As a true ISO 15552 profile cylinder, it serves as a direct dimensional direct replacement for other ISO 15552 cylinders, utilizing a G3/8 port, M16x1.5 rod thread, 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.
