About the Airtac SAI80 Standard Air Cylinder SAI80X300S
The AirTAC SAI80X300-S is a double-acting ISO 15552 profile cylinder featuring an 80mm bore and a 300mm stroke. It generates 2513N of push force and 2268N of pull force at 0.5 MPa, making it well-suited for medium-to-heavy actuation tasks. The integrated magnet allows for precise end-of-stroke detection using CMSE or DMSE sensor switches in the dual barrel grooves.
This model utilizes a standard carbon steel piston rod and a PT tapered G3/8 port. For higher thermal demands, the seal architecture can be upgraded from standard TPU to Viton, extending operational reliability in elevated temperature environments.

Where the Airtac SAI80 Standard Air Cylinder SAI80X300S Is Used
Material Handling
Ideal for pushing or lifting heavy pallets and product totes over a 300mm travel distance on automated conveyor lines.
Packaging Equipment
Provides the robust linear motion needed for sealing, folding, or forming heavy cardboard packaging at high cycle rates.
Clamping Fixtures
Delivers 2513N of thrust at 0.5 MPa for securing heavy workpieces during machining or assembly operations.
Is the Airtac SAI80 Standard Air Cylinder SAI80X300S the Right Cylinder?
Select this 80mm bore when an application requires more thrust than the 63mm variant (1559N at 0.5 MPa) but less than the 100mm class (3927N at 0.5 MPa). Because this unit features a 300mm stroke, side-load-induced bending stress on the rod bearing is a key consideration; using an external guide rail or a fully guided cylinder is recommended to prevent premature wear.
This SAI80X300-S configuration includes a magnet for position sensing, a G3/8 PT port, and an adjustable air cushion at both ends. Note that the pneumatic cushion only decelerates the piston near stroke limits and does not lock the load; if position holding without air pressure is required, specify the SAIL or BSAI locking variant.
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 SAI80X300S FAQ
At 0.5 MPa, this double-acting cylinder provides 2513N of push force and 2268N of pull force. The maximum theoretical force at 1.0 MPa is 513 kgf.
Yes. The SAI80X300-S is dimensionally interchangeable per the ISO 15552 standard, allowing it to drop into existing ISO 15552 mounting interfaces without requiring a new footprint.
