About the Airtac SAI80 Standard Air Cylinder SAI80X115S
The AirTAC SAI80X115-S is a double-acting ISO 15552 profile cylinder offering 2513 N of push force and 2268 N of pull force at 0.5 MPa. This 80 mm bore unit with a 115 mm stroke is engineered for heavy-duty positioning and high-cycle automation. Its extruded aluminum barrel omits tie rods, presenting a clean exterior that resists contamination.
Because this variant includes the -S magnet option, it directly supports CMSE and DMSE electronic switches via the integrated sensor grooves on both sides of the barrel. The standard carbon steel piston rod provides durable service, and operators can specify NBR seals for specific fluid compatibility if the default TPU elastomers are unsuitable.

Where the Airtac SAI80 Standard Air Cylinder SAI80X115S Is Used
Heavy Press Operations
Provides the robust 2513 N thrust at 0.5 MPa needed for stamping, riveting, and assembling dense metal components.
Bulk Material Diversion
Drives heavy-duty diverters and gating mechanisms on high-throughput packaging and logistics lines.
Large Clamp Fixtures
Secures oversized workpieces during CNC machining or welding by applying consistent mechanical clamping force.
Is the Airtac SAI80 Standard Air Cylinder SAI80X115S the Right Cylinder?
Select this 80 mm bore when an application requires upward of 2500 N of thrust but does not warrant the 3927 N output of a 100 mm counterpart. The 115 mm stroke is optimal for short, powerful transitions. If your mechanism loses air pressure, the standard SAI cylinder will drift and cannot sustain a load; for fail-safe holding, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant.
This model ensures a dimensionally interchangeable ISO 15552 mounting interface. Replacement configurations should match the 80 mm bore, 115 mm stroke, G3/8 PT port, and appropriate mounting accessory (such as an FA flange or TC trunnion). The -S magnet is required for any electronic position sensing.

- ✓ 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 SAI80X115S FAQ
At 0.5 MPa, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
Yes, the -S suffix indicates a magnetic piston designed to work seamlessly with CMSE and DMSE sensor switches in the dual barrel grooves.
