About the Airtac SAI80 Standard Air Cylinder SAI80X375S
The AirTAC SAI80X375-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 2513 N at 0.5 MPa and a pull force of 2268 N, making it well-suited for moving substantial loads over a 375 mm stroke. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet (-S) for non-contact position sensing. The barrel features sensor grooves on both sides, allowing seamless installation of CMSE or DMSE reed switches without requiring additional brackets. Fluid supply is driven through PT tapered G3/8 ports, and the unit relies on adjustable air cushions at both ends to decelerate the payload smoothly.

Where the Airtac SAI80 Standard Air Cylinder SAI80X375S Is Used
Heavy Stamping
Drives robust metal-forming and stamping presses where 2513 N of push force is necessary to deform components over a 375 mm travel distance.
Pallet Diversion
Actuates heavy-duty lane diverters on packaging lines, using the magnetic piston and dual sensor grooves to confirm full extension in high-speed sorting.
Material Lift
Raises and lowers heavy industrial chutes or lift gates, benefiting from the adjustable end cushions to safely brake the 375 mm stroke motion.
Is the Airtac SAI80 Standard Air Cylinder SAI80X375S the Right Cylinder?
Selecting this 80 mm bore over the smaller 63 mm variant is appropriate when your application requires more thrust than the 1559 N provided by the 63 mm bore at 0.5 MPa. Conversely, if your system demands even greater power, stepping up to the 100 mm bore yields 3927 N of push force. For a 375 mm stroke, the unsupported piston rod is susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder body is strongly recommended to prevent premature rod-bearing wear.
Because this is a standard double-acting cylinder, exhausting the air supply or centering the directional control valve will cause the piston to drift and drop. The integrated adjustable cushions only decelerate the mass near the stroke end and do not function as a locking mechanism. If your machinery must hold a vertical load safely without continuous air pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder.
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 SAI80 Standard Air Cylinder SAI80X375S FAQ
At an operating pressure of 0.5 MPa, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 3518 N.
Yes, the SAI80X375-S is dimensionally interchangeable per ISO 15552. You can drop it into existing ISO 15552 mounting footprints and use standard PT G3/8 porting, but always verify overall length and cushion dimensions against your specific legacy equipment.
