About the Airtac SAI80 Standard Air Cylinder SAI80X750
The AirTAC SAI80X750 is a double-acting ISO 15552 profile cylinder engineered to deliver 2513 N of push force at 0.5 MPa, scaling up to 4523 N at 0.9 MPa. This 80mm bore unit features a 750mm stroke, making it a robust choice for heavy-duty automation requiring substantial travel.
Constructed with an extruded aluminum barrel and standard carbon steel piston rod, it includes adjustable air cushions at both ends to absorb kinetic energy. The barrel also features dual-sided sensor grooves, allowing for flexible mounting of CMSE or DMSE proximity switches when position feedback is required.

Where the Airtac SAI80 Standard Air Cylinder SAI80X750 Is Used
Material Handling
Drives large heavy-duty pallet lifts and transfers over extended 750mm cycles.
Automotive Assembly
Actuates heavy clamping fixtures and robotic welding gun clearances.
Plastic Injection
Operates large ejection mechanisms requiring high force and long travel.
Is the Airtac SAI80 Standard Air Cylinder SAI80X750 the Right Cylinder?
Selecting this 80mm bore over the smaller 63mm option (which provides 1559 N at 0.5 MPa) is ideal when your application requires significantly higher thrust. If even greater force is needed, stepping up to the 100mm bore yields 3927 N at the same pressure.
Because this model utilizes a 750mm stroke, the unsupported rod length is highly susceptible to bending under side loads. To prevent premature rod-bearing wear and seal failure, implement an external linear guide rail or utilize a guided cylinder carriage. Note that the standard SAI does not hold position upon air loss; for fail-safe load holding, consider the BSAI clamp-lock variant or an external rod lock.
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.
