About the Airtac SAI80 Standard Air Cylinder SAI80X375
The AirTAC SAI80X375 is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and 375mm stroke. It generates 2513 N of push force at 0.5 MPa, making it well-suited for heavy-duty handling and clamping tasks. The extruded aluminum barrel is designed without tie-rods and includes integrated sensor grooves on both sides for flexible position detection.
This model comes standard with a carbon steel piston rod for high structural strength and uses PT tapered port threads. It features adjustable air cushions at both ends to absorb impact energy. Because it lacks a magnetic piston, external proximity switches or in-cushion sensing cannot be used; add the -S suffix if electronic position feedback is required.

Where the Airtac SAI80 Standard Air Cylinder SAI80X375 Is Used
Heavy-Duty Clamping
Secures large metal castings or heavy timber during CNC machining with 2513 N of thrust at 0.5 MPa.
Pallet Diversion
Pushes fully loaded pallets off a high-speed packaging line using the 375mm stroke length.
Press Ejection
Ejects formed parts from mid-size stamping presses, utilizing adjustable cushions to cushion the stroke end.
Is the Airtac SAI80 Standard Air Cylinder SAI80X375 the Right Cylinder?
Selecting this 80mm bore makes sense when the 63mm option (providing 1559 N at 0.5 MPa) is insufficient for your load, but you want to avoid the larger footprint and higher air consumption of the 100mm version. The G3/8 port ensures adequate flow to maintain a 30-800 mm/s speed range.
At 375mm of stroke, the unsupported piston rod is susceptible to bending under side loads. To prevent premature rod-bearing wear, mount this cylinder using a trunnion (TC) or clevis (CA/CB) accessory for self-alignment, or guide the load externally. Note that the standard SAI does not hold its position if air pressure drops; for fail-safe load holding, specify the SAIL pneumatically-released lock or BSAI clamp-lock variant instead of relying on the cushion.
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 SAI80X375 FAQ
At 0.5 MPa, it provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
Yes. The SAI80X375 is dimensionally interchangeable per ISO 15552 and uses a standard G3/8 port, making it a direct drop-in replacement for other ISO 15552 profile cylinders.
