About the Airtac SAI100 Standard Air Cylinder SAI100AX325S
The AirTAC SAI100X325-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a push force of 3927 N at 0.5 MPa, this 100 mm bore unit is designed to handle substantial loads over its 325 mm stroke. The extruded aluminum barrel eliminates tie-rods, providing a smooth exterior that resists contamination while maintaining strict dimensional interchangeability with other ISO 15552 standard cylinders.
This specific configuration includes a SUS420J2 stainless steel rod for enhanced corrosion resistance compared to standard carbon steel. The -S suffix indicates a built-in magnet for use with CMSE or DMSE reed switches, which seat directly into the dual sensor grooves machined on both sides of the barrel. Fluid porting utilizes PT tapered threads, ensuring a robust, mechanical seal in pneumatic systems.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX325S Is Used
Heavy-Duty Pressing
Ideal for applying consistent 3927 N clamping or pressing forces in automated metalworking and assembly cells.
Material Diversion
Provides the robust stroke and power needed to pivot heavy product diverters on high-throughput packaging conveyors.
Large Gate Actuation
Actuates substantial machine safety gates or heavy industrial chutes where a long 325 mm travel is required.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX325S the Right Cylinder?
With a 100 mm bore yielding 3927 N of push force at 0.5 MPa, stepping down to an 80 mm bore drops the output to 2513 N, which may be insufficient for high-inertia loads. Conversely, moving up to a 125 mm bore increases force to 6136 N but requires a larger G1/2 port and heavier mounting hardware. The 325 mm stroke on this model falls within the 1500 mm standard maximum, but it is long enough that side-load induced rod-bearing bending becomes a factor; always use an external guide rail or a guided cylinder carriage to prevent premature seal wear and piston drift.
Because this is a standard double-acting cylinder, the adjustable air cushions at both ends only decelerate the piston near the stroke extremes. They do not lock or hold the load if air pressure is lost or the directional valve is centered. If your machinery requires true fail-safe position holding under zero pressure, specify the SAIL variant with an air-released lock, or integrate an external pilot-operated check valve into the pneumatic circuit.
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 SAI100 Standard Air Cylinder SAI100AX325S FAQ
At a standard operating pressure of 0.5 MPa, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X325-S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders of the same bore and stroke, provided your mounting accessories and PT port connections match.
