About the Airtac SAI40 Standard Air Cylinder SAI40AX195
The AirTAC SAI40X195 is a double-acting ISO 15552 profile cylinder engineered to deliver 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa. This 40 mm bore unit with a 195 mm stroke bridges the gap between compact assemblies and mid-range automation tasks. The extruded aluminum barrel omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
Configured here with an SUS420J2 stainless steel piston rod (material code A), this model offers enhanced resistance to moisture and minor corrosion compared to standard carbon steel. It uses PT tapered port threads (G1/4) and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches requires adding the -S option at order.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX195 Is Used
Component Clamping
Secures machined metal parts during secondary milling operations, utilizing its 879 N push force at 0.7 MPa to prevent workpiece shifting.
Package Diverting
Actuates a routing gate on a packaging line, where the 195 mm stroke provides sufficient travel to redirect medium-sized cartons between belts.
Material Ejection
Pushes molded plastic parts out of an injection press cavity, taking advantage of the SUS420J2 rod's resistance to factory humidity.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX195 the Right Cylinder?
Select this 40 mm bore when a 32 mm cylinder (providing 402 N at 0.5 MPa) lacks the necessary thrust, but a 50 mm unit (982 N at 0.5 MPa) would be physically oversized. Because the 195 mm stroke approaches the 300 mm threshold, evaluate your assembly for potential rod-bearing bending under side loads. If the application cannot guarantee perfect axial alignment, utilize an external guide rail or switch to a guided cylinder to preserve seal integrity.
As a dimensionally interchangeable ISO 15552 profile cylinder, this unit serves as a direct replacement for other standard cylinders sharing the same 40 mm bore, 195 mm stroke, G1/4 port, and mounting accessory footprint. Note that the standard adjustable air cushions only decelerate the piston at stroke ends; they will not hold a load if air pressure drops. For position holding without live pressure, consider the SAIL locking variant or an external pilot-operated check valve.
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 SAI40 Standard Air Cylinder SAI40AX195 FAQ
