About the Airtac SAI100 Standard Air Cylinder SAI100BX275S
The AirTAC SAI100X275-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 5497 N of push force at 0.7 MPa, this 100 mm bore actuator easily manages substantial loads across its 275 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. Equipped with a magnet (-S), it supports direct mounting of CMSE or DMSE reed switches along the dual sensor grooves molded into the barrel profile.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX275S Is Used
Heavy Stamping
Provides the necessary 5497 N push force at 0.7 MPa to actuate large mechanical presses and form rigid metal components.
Pallet Diversion
Utilizes the 275 mm stroke to push heavy loaded pallets smoothly off high-throughput material handling conveyor lines.
Washdown Actuation
The SUS304 stainless steel rod withstands moisture and harsh cleaning chemicals in food processing or packaging machinery.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX275S the Right Cylinder?
Selecting this 100 mm bore makes sense when a 80 mm bore (providing 3518 N push at 0.7 MPa) cannot meet your thrust requirements. Because this model features a 275 mm stroke, the extended rod is susceptible to bending under side loads; always use external guide rails or a guided cylinder carriage to prevent premature rod-bearing wear. Note that the adjustable air cushions at both ends only serve to decelerate the piston near stroke end and will not hold a load if air pressure drops. For dead-load holding, integrate an external pilot check valve or specify a SAIL variant. As a true ISO 15552 cylinder, it serves as a drop-in replacement for any standard 100 mm bore, 275 mm stroke, G1/2 port profile cylinder with matching mounting accessories like FA flanges or TC trunnions.
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 SAI100BX275S FAQ
At a standard operating pressure of 0.7 MPa, this 100 mm bore cylinder generates 5497 N of push force and 3681 N of pull force. At 0.5 MPa, the push force is 3927 N.
Yes. The SAI series is manufactured to strict ISO 15552 dimensional standards, meaning it is dimensionally interchangeable with other ISO 15552 profile cylinders of the same 100 mm bore and 275 mm stroke, provided you match the G1/2 port and mounting interface.
