About the Airtac SAI80 Standard Air Cylinder SAI80X145
The AirTAC SAI80X145 is a double-acting ISO 15552 profile cylinder offering 2513N of push force and 2268N of pull force at 0.5 MPa. The 145mm stroke provides an optimal extension length for medium-duty positioning tasks. Featuring an extruded aluminum barrel, it integrates seamlessly into standardized ISO 15552 mounting interfaces.
This specific configuration utilizes a standard carbon steel piston rod and PT tapered port threads. Because no magnet is specified, external reed switches like CMSE or DMSE cannot be mounted; if sensor feedback is required, an SAI80X145-S variant must be specified instead.

Where the Airtac SAI80 Standard Air Cylinder SAI80X145 Is Used
Automated Pressing
Provides 2513N of thrust at 0.5 MPa for pressing bearings, pins, and small components into housings on an assembly line.
Product Diversion
The 145mm stroke actuates diverter arms to route medium-weight packages across material handling conveyors.
Clamp Fixturing
Holds workpieces securely in machining and welding cells where a robust 80mm bore delivers reliable holding force.
Is the Airtac SAI80 Standard Air Cylinder SAI80X145 the Right Cylinder?
Selecting this 80mm bore makes sense when a 63mm bore (1559N push at 0.5 MPa) lacks sufficient thrust for your load, but a 100mm bore (3927N at 0.5 MPa) would be physically oversized. The 145mm stroke is well below the 300mm threshold, so rod-bearing bending from side loads is less critical than on longer units. However, for applications with heavy off-center loads, a guided cylinder is still recommended.
This SAI80X145 uses a G3/8 PT port and can be paired with various ISO 15552 mounting accessories such as LB foot brackets or TC trunnion blocks. Since this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered; for position holding, consider the SAIL or BSAI locking variants.
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 SAI80X145 FAQ
At 0.5 MPa, the SAI80X145 generates 2513N of push force and 2268N of pull force. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 513 kgf.
Yes, the SAI80X145 is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile cylinders, provided you match the 80mm bore, 145mm stroke, and G3/8 port.
