About the Airtac SAI80 Standard Air Cylinder SAI80X125S
The AirTAC SAI80X125-S is a double-acting profile cylinder built to the ISO 15552 mounting interface. It generates 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it a robust choice for medium-to-heavy industrial handling. The 125 mm stroke provides a compact extension for clamping, lifting, and pressing tasks.
This variant includes a built-in magnet for proximity sensing, allowing seamless integration with CMSE or DMSE reed switches along the dual sensor grooves on the extruded aluminum barrel. The standard carbon steel piston rod offers durable service in general pneumatic environments, while the adjustable air cushions at both ends ensure smooth end-of-stroke deceleration.

Where the Airtac SAI80 Standard Air Cylinder SAI80X125S Is Used
Automated Pressing
Provides reliable 2513 N pressing force for assembling bearings or seating pins in automated machinery.
Pallet Diverter
Uses the 125 mm stroke to push heavy pallets onto secondary packaging lines at high operating speeds.
Heavy Clamping
Secures large metal workpieces during machining operations, utilizing adjustable cushions to soften impact.
Is the Airtac SAI80 Standard Air Cylinder SAI80X125S the Right Cylinder?
If an application requires less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa, whereas moving up to a 100 mm bore provides 3927 N. The 125 mm stroke is well below the 1500 mm maximum standard stroke, so side-load stress on the rod bearing is minimal for this length.
As a true ISO 15552 profile cylinder, this unit serves as a drop-in replacement for any standard ISO 15552 cylinder with an 80 mm bore and 125 mm stroke. It features a PT tapered G3/8 port and supports standard mountings like FA flange or TC trunnion. Note that a standard SAI does not hold loads safely upon air loss; for fail-safe holding, specify the SAIL or BSAI variant.
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 SAI80X125S FAQ
At 0.5 MPa, the cylinder provides 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. It works directly with CMSE or DMSE switches fitted into the sensor grooves on both sides of the barrel.
