About the Airtac SAI80 Standard Air Cylinder SAI80X750S
The AirTAC SAI80X750-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 2513 N at 0.5 MPa and a pull force of 2268 N, making it well-suited for driving substantial loads over its 750 mm stroke. The extruded aluminum barrel design omits tie rods, offering a clean exterior that resists mechanical wear.
This specific configuration includes a magnet for position sensing, allowing seamless integration with CMSE or DMSE reed switches fitted into the dual sensor grooves. It features standard carbon steel piston rod material and PT tapered port threads. For applications facing thermal extremes, the standard TPU seals can be swapped for high-temperature Viton (H) or NBR (N) variants.

Where the Airtac SAI80 Standard Air Cylinder SAI80X750S Is Used
Pallet Transfer
Drives heavy pallets along extended conveyor lines, utilizing the 750 mm stroke to shift workpieces between machining stations.
Press Ejection
Exerts 2513 N of push force at 0.5 MPa to eject formed metal or plastic components from heavy stamping presses.
Vertical Lift Gate
Actuates large lifting gates or heavy material handling doors, relying on the magnet and CMSE sensors for precise end-of-stroke confirmation.
Is the Airtac SAI80 Standard Air Cylinder SAI80X750S the Right Cylinder?
Selecting this 80 mm bore cylinder is optimal when a machine requires thrust beyond the 1559 N offered by a 63 mm bore, but without stepping up to the 3927 N capacity of a 100 mm bore. At 750 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing failure, always guide the load externally or utilize a dedicated guided cylinder carriage.
This model is dimensionally interchangeable per ISO 15552, serving as a direct drop-in replacement for other standard profile cylinders. It uses a G3/8 PT port, accommodates standard mounting accessories like TC trunnion or FA flange brackets, and includes the -S magnet option for sensor tracking. Note that standard double-acting cylinders drift when air pressure is removed; if your cycle demands fail-safe load holding, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead.
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 SAI80X750S FAQ
This 80 mm bore cylinder generates a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.7 MPa, the push force increases to 3518 N.
Yes, the SAI80X750-S is a true ISO 15552 profile cylinder, meaning its mounting dimensions are interchangeable with other ISO 15552 standard cylinders of the same bore size.
