About the Airtac SAI80 Standard Air Cylinder SAI80X800SH
The AirTAC SAI80X800-S is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and an 800mm stroke. It delivers a robust push force of 2513 N at 0.5 MPa and a maximum pull of 2268 N, making it suitable for heavy-duty linear motion tasks. The extruded aluminum barrel includes sensor grooves on both sides, and the included -S magnet enables seamless integration with CMSE and DMSE reed switches for precise position detection.
This specific configuration is built for demanding environments, utilizing high-temperature Viton (FKM) seals that expand the operating range up to +70 C while maintaining excellent chemical resistance. The piston rod is constructed from standard carbon steel for high tensile strength. As a genuine AirTAC component, it ensures reliable, long-lasting automation performance.

Where the Airtac SAI80 Standard Air Cylinder SAI80X800SH Is Used
Automotive Body Welding
Ideal for moving heavy chassis components along large welding lines where the Viton seals withstand high ambient heat and the 800mm stroke provides necessary reach.
Pallet Transfer System
Pushes loaded pallets between conveyor sections, utilizing the 2513 N push force to overcome inertia and the -S magnet for end-of-stroke confirmation.
Large Press Loading
Feeds heavy sheet metal blanks into a hydraulic press, relying on the robust carbon steel rod and ISO 15552 mounting interface to handle repetitive shock loads.
Is the Airtac SAI80 Standard Air Cylinder SAI80X800SH the Right Cylinder?
An 80mm bore provides substantial thrust, but if your application requires less force, stepping down to a 63mm bore yields 1559 N of push force at 0.5 MPa, which may offer a more compact footprint. Conversely, moving up to a 100mm bore increases the push force to 3927 N for heavier loads. At an 800mm stroke, the unsupported piston rod is highly susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This model uses a G3/8 PT tapered port and supports standard ISO 15552 mounting accessories like TC trunnion or FA flange brackets. Remember that standard double-acting cylinders exhaust and drift when air pressure is lost; if your setup requires position holding without live pressure, consider the SAIL variant with an air-released lock or the BSAI 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 SAI80X800SH FAQ
At 0.5 MPa, this 80mm bore cylinder generates a push force of 2513 N and a pull force of 2268 N. If operated at 0.7 MPa, the push force increases to 3518 N.
Yes, the SAI80X800-S is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders, provided your mounting interface and G3/8 port match.
