About the Airtac SAI63 Standard Cylinder SAI63AX195
The AirTAC SAI63X195 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a custom 195mm stroke. Because this stroke falls outside the standard increments, it is provided as a made-to-order unit to suit precise machinery spacing requirements. It delivers a robust 1559N push force at 0.5MPa, making it well-suited for medium-duty industrial actuation.
This configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced resistance to surface corrosion and scratching in humid environments. Fluid supply connections use PT tapered port threads, and the extruded aluminum barrel includes sensor grooves on both sides for direct CMSE or DMSE switch mounting.

Where the Airtac SAI63 Standard Cylinder SAI63AX195 Is Used
Material Handling
Provides the 1559N push force needed to divert or gate heavy packages on automated conveyor lines.
Machine Clamping
Secures workpieces during machining operations, utilizing its 195mm stroke to accommodate varying part sizes.
Assembly Automation
Drives pressing and insertion stations where a custom 195mm stroke is required to clear tooling fixtures.
Is the Airtac SAI63 Standard Cylinder SAI63AX195 the Right Cylinder?
With a 195mm stroke, this cylinder requires careful attention to side-load management. Long unsupported rods are prone to bending under lateral forces; utilizing an external guide rail or a fully guided cylinder will prevent premature rod-bearing wear and seal failure.
If your application requires holding a load in place during an air pressure loss or exhaust event, note that the standard SAI does not function as a lock or brake. For positive position holding without live pressure, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. This model serves as a drop-in replacement for any ISO 15552 cylinder matching its 63mm bore, 195mm stroke, G3/8 port, and standard mounting accessories like the TC trunnion or FA flange.
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 SAI63AX195 FAQ
At an operating pressure of 0.5MPa, the SAI63X195 cylinder provides a push force of 1559N and a pull force of 1402N. At 0.7MPa, the push force increases to 2182N.
Yes, the SAI63X195 is dimensionally interchangeable per ISO 15552. You can drop it in to replace other ISO 15552 profile cylinders with a 63mm bore, 195mm stroke, G3/8 port, and matching mounting interface.
