About the Airtac SAI100 Standard Air Cylinder SAI100X275
The AirTAC SAI100X275 is a double-acting ISO 15552 profile cylinder offering a robust 3927 N push force at 0.5 MPa. This 100 mm bore and 275 mm stroke configuration is ideal for heavy-duty actuation requiring substantial linear thrust. The extruded aluminum barrel design omits traditional tie rods, providing a clean exterior that integrates seamlessly into modern machinery.
This specific unit is configured with standard carbon steel piston rod material and PT tapered port threads. Because it lacks an integrated magnet (-S not specified), it does not support direct reed or solid-state sensor mounting. For applications requiring position feedback, the magnet-equipped variant is necessary, or you can explore related types like the SAID double-rod cylinder for balanced opposing forces.

Where the Airtac SAI100 Standard Air Cylinder SAI100X275 Is Used
Heavy Stamping
Provides the necessary 3927 N push force at 0.5 MPa to drive heavy stamping and forming presses reliably.
Pallet Diversion
Actuates robust routing arms to divert heavy pallets along high-throughput material handling conveyors.
Automated Presses
Ideal for driving automated assembly presses that require consistent high-force clamping over a 275 mm travel.
Is the Airtac SAI100 Standard Air Cylinder SAI100X275 the Right Cylinder?
Selecting this 100 mm bore provides 3927 N of thrust at 0.5 MPa, offering a significant step up from the 63 mm bore (1559 N) for high-inertia loads. If this proves excessive for your application, stepping down to the 80 mm bore yields 2513 N. At a 275 mm stroke, the unsupported rod length is moderate, but side-load management remains important to prevent premature rod-bearing wear.
This model features adjustable air cushions at both ends to decelerate the piston smoothly, but these cushions do not hold the load in place when air pressure is removed. If your application requires true position holding without constant live pressure, consider the SAIL variant with an air-released lock or an external pilot-operated check valve. As a genuine ISO 15552 profile cylinder, it serves as a drop-in replacement for other standard ISO 15552 cylinders, matching the 100 mm bore, 275 mm stroke, G1/2 port, and standard mounting accessories.
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 SAI100 Standard Air Cylinder SAI100X275 FAQ
The SAI100X275 cylinder delivers a push force of 3927 N at 0.5 MPa and 5497 N at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa.
Yes, the SAI100X275 is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, provided the G1/2 port and mounting interface match.
