About the Airtac SAI100 Standard Air Cylinder SAI100BX275
The AirTAC SAI100X275 is a double-acting ISO 15552 profile cylinder delivering 3927N of push force and 3681N of pull force at 0.5 MPa. With a 100mm bore and 275mm stroke, it is built for heavy-duty positioning and high-inertia load handling.
This specific configuration incorporates a SUS304 stainless steel piston rod for superior corrosion resistance in humid or washdown environments. It uses PT tapered port threads and lacks a magnetic piston, meaning it is optimized purely for mechanical actuation without electronic position sensing.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX275 Is Used
Heavy Stamping Press
Provides the substantial 3927N force required to actuate heavy stamping and forming presses in metal fabrication lines.
Pallet Diverter
Handles the robust lateral diversion of heavy-loaded pallets on assembly line conveyors without stalling under high inertia.
Large Clamp Fixture
Secures large automotive or structural components during machining, utilizing the 275mm stroke to accommodate varying part widths.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX275 the Right Cylinder?
Selecting this 100mm bore over the smaller 80mm variant upgrades your thrust from 2513N to 3927N at 0.5 MPa, providing the necessary power for heavier fixtures. At 275mm of stroke, the unsupported rod length is significant; side loads can bend the rod bearing, so utilizing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature wear.
Because it is a standard double-acting cylinder, the SAI100X275 cannot hold a load in place if air pressure is lost or the valve is centered. For gravity-loaded vertical applications requiring fail-safe position holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. This model ensures seamless interchangeability with other ISO 15552 mounting interface cylinders.
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.
