About the Airtac SAI40 Standard Air Cylinder SAI40X375
The AirTAC SAI40X375 is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and 375mm stroke. It generates 628N of push force at 0.5 MPa, making it well-suited for mid-range automation tasks requiring a lengthy extension. The extruded aluminum barrel omits traditional tie rods, providing a clean exterior that resists mechanical contamination.
This specific configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because no magnet is specified, it operates without sensor grooves being populated. For environments exceeding standard temperature limits, the factory offers Viton (H) seals which maintain structural integrity under thermal stress.

Where the Airtac SAI40 Standard Air Cylinder SAI40X375 Is Used
Material Diversion
Actuates long-stroke diverter arms on packaging conveyors to route medium-weight goods into secondary processing lanes.
Vertical Lift Gates
Raises and lowers access gates on automated storage retrieval systems, utilizing the full 375mm stroke for clear personnel passage.
Component Ejection
Pushes machined aluminum parts out of a CNC enclosure, using the 628N push force at 0.5 MPa to clear the cutting zone.
Is the Airtac SAI40 Standard Air Cylinder SAI40X375 the Right Cylinder?
Selecting this 40mm bore over the smaller 32mm variant upgrades your push force from 402N to 628N at 0.5 MPa, while stepping up to the 50mm bore yields 982N. The 375mm stroke is a standard length but requires careful mechanical integration. At this extension, the unsupported carbon steel rod is highly susceptible to bending under side loads.
To prevent premature seal wear and rod bearing failure, mount an external guide rail or employ a fully guided cylinder mechanism for heavy offset loads. This unit functions as a drop-in replacement for any ISO 15552 profile cylinder matching the 40mm bore, 375mm stroke, and G1/4 port footprint. If the application demands intermediate stopping or fail-safe load holding when air pressure is removed, pair the cylinder with an external pilot-operated check valve or transition to the SAIL locking variant.
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 SAI40X375 FAQ
At a 0.5 MPa operating pressure, this 40mm bore cylinder provides 628N of push force and 528N of pull force. Increasing pressure to 0.7 MPa yields 879N of push force.
Yes, the SAI40X375 is dimensionally interchangeable with any standard ISO 15552 profile cylinder sharing the 40mm bore, 375mm stroke, and G1/4 port specifications.
