About the Airtac SAI40 Standard Air Cylinder SAI40AX700
The AirTAC SAI40X700 is a double-acting ISO 15552 profile cylinder built for long-stroke linear motion. It delivers 628N of push force at 0.5 MPa and features a 700mm extension. The extruded aluminum barrel omits tie-rods, providing a clean exterior that conforms to standardized mounting dimensions.
This specific configuration incorporates a SUS420J2 stainless steel rod for enhanced corrosion resistance. It uses PT tapered port threads and lacks a piston magnet, meaning it is optimized for mechanical actuation rather than electronic position sensing.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX700 Is Used
Material Transfer
Pushes products or pallets along extended conveyor lines where a 700mm reach is required.
Long-Reach Diverting
Actuates sorting arms across wider sorting lanes, utilizing the 628N push force at 0.5 MPa.
Equipment Ejection
Ejects machined parts from machinery over a long distance, keeping the work area clear.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX700 the Right Cylinder?
Stepping up to the 50mm bore yields 982N push force at 0.5 MPa, which is necessary if the 40mm's 628N proves insufficient for your load. At a 700mm stroke, the unsupported rod length is highly susceptible to bending under side loads. Implement an external guide rail or select a fully guided cylinder to prevent premature rod-bearing wear.
Because this is a standard double-acting cylinder, it will drift and drop if air pressure is lost or the valve is centered. To safely hold a load without live pressure, integrate an external pilot-operated check valve or specify the SAIL locking variant. For a direct replacement, match the 40mm bore, 700mm stroke, G1/4 port, and your required mounting accessory.
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 SAI40AX700 FAQ
The cylinder provides 628N of push force and 528N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 879N.
No, the standard SAI cylinder will drift and drop if air pressure is lost. For vertical load holding without continuous pressure, use the SAIL lock variant or an external rod lock.
