About the Airtac SAI100 Standard Air Cylinder SAI100AX275
The AirTAC SAI100X275 is a double-acting ISO 15552 profile cylinder engineered to deliver a robust 5497 N of push force at 0.7 MPa. This 100 mm bore and 275 mm stroke configuration is tailored for heavy-duty machinery requiring substantial linear motion over a mid-range distance.
Built with a SUS420J2 stainless steel piston rod, this model provides excellent corrosion resistance and durability in demanding environments. The extruded aluminum barrel features sensor grooves on both sides for direct CMSE or DMSE switch mounting, while the PT tapered port threads guarantee a reliable, leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX275 Is Used
Heavy-Duty Pressing
Ideal for applying 5497 N of force at 0.7 MPa to seat bearings, form light sheet metal, or assemble heavy components in automated presses.
Pallet Diversion
Provides the necessary thrust to push heavy loaded pallets onto secondary conveyor lanes or lift goods in high-throughput distribution centers.
Clamping Fixtures
Secures large workpieces or heavy castings during CNC machining, welding, or industrial assembly operations where a rigid, high-force clamp is required.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX275 the Right Cylinder?
Choosing this 100 mm bore makes sense when a 80 mm bore (providing 3518 N at 0.7 MPa) cannot generate enough push force for your application. If your load requirements are lower, dropping to an 80 mm bore saves space and air consumption. Because this 275 mm stroke is a non-standard intermediate length, ensure your mounting setup accommodates the exact extended length.
For strokes of 300 mm or more, side loads can cause excessive bending stress on the rod bearing. If your application approaches this threshold or involves offset loads, utilize an external guide rail or a guided cylinder to prevent premature wear. Remember that a standard SAI cylinder will drift if air pressure is lost; for position holding, select the SAIL variant or an external rod lock.
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.
