About the Airtac SAI80 Standard Air Cylinder SAI80X330SFTC
The AirTAC SAI80X330-S is a double-acting ISO 15552 profile cylinder engineered to deliver 2513 N of push force and 2268 N of pull force at 0.5 MPa. Its 330 mm stroke is well-suited for mid-range linear actuation tasks requiring substantial travel. Because it is a profile cylinder with an extruded aluminum barrel, it omits tie-rods for a cleaner exterior.
This specific configuration includes a magnet for use with CMSE and DMSE sensor switches, which ride securely in the dual grooves machined into the barrel sides. The standard carbon steel piston rod provides durable service, while the integrated adjustable air cushions at both ends decelerate the piston to prevent end-cap impact.

Where the Airtac SAI80 Standard Air Cylinder SAI80X330SFTC Is Used
Automated Stamping Press
Provides the 2513 N push force required to actuate medium-duty stamping and forming dies over a 330 mm travel distance.
Pallet Diverting Arm
Extends a 330 mm routing gate to redirect heavy product pallets between conveyor lines, using the FTC trunnion mount for central pivot support.
Material Lift Gate
Raises and lowers a 330 mm safety barrier or sorting flap on a packaging machine, relying on the adjustable cushions to absorb kinetic energy.
Is the Airtac SAI80 Standard Air Cylinder SAI80X330SFTC the Right Cylinder?
Choose this 80 mm bore when a 63 mm bore (1559 N push at 0.5 MPa) lacks the necessary thrust, but a 100 mm bore (3927 N push at 0.5 MPa) would be physically oversized. The 330 mm stroke falls within the standard range, but strokes of 300 mm or more require careful attention to side loads. An unsupported rod of this length can bend under lateral stress, so utilizing an external guide rail or a guided cylinder module is strongly recommended to prevent premature rod-bearing wear.
This model features PT tapered port threads, an FTC trunnion mounting accessory, and a magnet for position sensing. As a dimensionally interchangeable ISO 15552 unit, it serves as a direct drop-in replacement for other ISO 15552 profile cylinders. Note that this standard cylinder does not hold loads when air pressure is removed; use the BSAI clamp-lock variant if your application requires failsafe position holding.
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.
