About the Airtac SAI80 Standard Air Cylinder SAI80X155
The AirTAC SAI80X155 is a double-acting ISO 15552 profile cylinder featuring a 155 mm stroke. Operating at 0.5 MPa, it generates 2513 N of push force and 2268 N of pull force. This specific 155 mm stroke is a non-standard, made-to-order length, offering a tailored solution for specialized actuation distances.
Built with an extruded aluminum barrel, this unit incorporates dual sensor grooves on both sides for CMSE or DMSE switches (requiring the -S magnet option). The standard configuration utilizes a robust carbon steel piston rod and PT tapered port threads to ensure a dependable, leak-free pneumatic connection in demanding industrial environments.

Where the Airtac SAI80 Standard Air Cylinder SAI80X155 Is Used
Automated Pressing
Provides reliable 2513 N pressing force at 0.5 MPa for assembling bearings or pinning components in light manufacturing lines.
Heavy Material Diversion
Actuates large lane changers or heavy-duty diverters on packaging conveyors where a 155 mm stroke precisely redirects product flow.
Custom Fixture Clamping
Secures oversized or irregularly shaped workpieces in custom machining fixtures, utilizing the exact 155 mm travel distance.
Is the Airtac SAI80 Standard Air Cylinder SAI80X155 the Right Cylinder?
When selecting this 80 mm bore, consider the neighboring 63 mm option if your application only requires 1559 N of push force at 0.5 MPa, as it saves valuable space. Conversely, if your system demands higher thrust up to 3927 N, stepping up to the 100 mm bore is recommended. Because 155 mm is a non-standard stroke, verify your exact end-of-stroke cushioning adjustments upon installation.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. The base configuration lacks a magnet and does not hold its load when air pressure is removed; for any position-holding requirements, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead.
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 SAI80X155 FAQ
At an operating pressure of 0.5 MPa, the SAI80X155 delivers a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
Yes. As a genuine ISO 15552 profile cylinder, its mounting interface and dimensions are interchangeable with other ISO 15552 standard cylinders, making it a drop-in replacement for that form factor.
