About the Airtac SAI80 Standard Air Cylinder SAI80BX115
The AirTAC SAI80X115 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 2513N push force at 0.5 MPa. Its 115mm stroke is well-suited for medium-duty positioning tasks requiring substantial thrust. Built with an extruded aluminum barrel, this tie-rod-less design ensures rigid, compact integration.
This specific configuration incorporates a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and lacks a standard magnet, relying purely on its mechanical output. Adjustable air cushions at both ends absorb impact, protecting your payloads.

Where the Airtac SAI80 Standard Air Cylinder SAI80BX115 Is Used
Heavy-Duty Clamping
Provides 2513N of clamping force at 0.5 MPa to secure thick metal plates during machining or welding operations.
Pallet Diversion
Extends 115mm to push heavy loaded pallets onto secondary packaging lines without requiring high operating pressures.
Press Ejection
Cycles rapidly to eject formed parts from hydraulic presses, utilizing the adjustable end cushions to prevent workpiece damage.
Is the Airtac SAI80 Standard Air Cylinder SAI80BX115 the Right Cylinder?
Select this 80mm bore when a 50mm cylinder (providing 982N at 0.5 MPa) lacks the necessary power, but a 100mm bore is physically oversized. For this 115mm stroke, side-load bending stress on the rod bearing is minimal, though external guides should still be used to prevent binding in rigid assemblies.
Because this is a standard double-acting cylinder, it will drift and drop if air pressure is lost or the valve centers. If your workflow requires true position holding without live pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. To match existing tooling, confirm the G3/8 port, your mounting accessory (such as FA flange or TC trunnion), and whether a -S magnet is needed for sensor tracking.
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 SAI80BX115 FAQ
At 0.5 MPa, the SAI80X115 generates 2513N of push force and 2268N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 3518N.
Yes. The SAI80X115 is dimensionally interchangeable per ISO 15552, meaning it matches the standardized mounting interface and envelope dimensions of equivalent ISO 15552 profile cylinders from other brands.
