About the Airtac SAI80 Standard Air Cylinder SAI80X120SHG
The AirTAC SAI80X120-S is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 2513N push force at 0.5 MPa, scaling up to 3518N at 0.7 MPa. Its 120mm stroke is well-suited for mid-length linear actuation tasks requiring substantial push and pull thrust. The extruded aluminum barrel omits tie-rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration incorporates high-temperature Viton (FKM) seals, expanding the operating envelope from -20 to +120 C for thermally demanding environments. It includes a magnetic piston (-S) for position detection via CMSE or DMSE switches, which seat neatly into the dual sensor grooves machined on both sides of the barrel. The standard carbon steel piston rod provides dependable tensile strength for industrial cycling.

Where the Airtac SAI80 Standard Air Cylinder SAI80X120SHG Is Used
Heavy-Duty Stamping
Drives medium-tonnage stamping and forming presses where the 3518N force at 0.7 MPa is required to seat or bend metal components reliably.
Pallet Diversion
Actuates heavy-duty lane diverters and pallet stops on high-throughput conveyor lines, utilizing the 120mm stroke to clear or block large product footprints.
High-Tact Clamping
Secures automotive or aerospace sub-assemblies during machining, leveraging the Viton seals to withstand nearby thermal processes or ambient heat.
Is the Airtac SAI80 Standard Air Cylinder SAI80X120SHG the Right Cylinder?
Selecting this 80mm bore makes sense when a 63mm cylinder falls short—yielding 2513N at 0.5 MPa compared to the 63mm's 1559N. If your application requires less force, stepping down to a 50mm bore offers 982N, conserving air volume. Because this unit uses a 120mm stroke, side-load stress on the rod bearing is minimal, though external guides are always recommended if the load is not perfectly axial.
For installations requiring the piston to maintain its position during a loss of air pressure, note that the standard adjustable air cushions only decelerate the rod at stroke ends and do not function as a locking mechanism. In safety-critical or dead-load scenarios, specify the SAIL variant with an air-released lock, or the BSAI bidirectional clamp-lock cylinder. This SAI80X120-S uses a G3/8 port, accepts standard ISO 15552 mounting accessories like FA flanges or TC trunnions, and its G-thread interface ensures straightforward plumbing.
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 SAI80X120SHG FAQ
At 0.5 MPa, this 80mm bore cylinder generates 2513N of push force and 2268N of pull force. If operating pressure is increased to 0.7 MPa, the push force rises to 3518N.
Yes, the SAI80X120-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mountings, provided your fluid porting matches the G3/8 thread and your sensor tracks accept the dual-groove profile barrel.
