About the Airtac SAI100 Standard Air Cylinder SAI100BX300S
The AirTAC SAI100X300-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation, delivering a robust push force of 3927 N at 0.5 MPa. Its 300 mm stroke is well-suited for extended travel requirements in material handling and large press operations. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and maintenance.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or chemically exposed environments. It is equipped with a magnetic piston (-S) for seamless integration with CMSE or DMSE reed switches via the dual sensor grooves machined into the barrel. Fluid ports utilize PT tapered threads, ensuring a reliable, leak-free pneumatic connection.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX300S Is Used
Automotive Body Pressing
Provides the necessary 3927 N push force at 0.5 MPa to form and stamp heavy sheet metal components in automotive assembly lines.
Pallet Transfer Diversion
Utilizes the 300 mm stroke to push heavy loaded pallets from a main conveyor line onto secondary packaging branches.
Heavy Lift Gate Actuation
Raises and lowers substantial loading dock gates, relying on the SUS304 rod for environmental protection against outdoor humidity.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX300S the Right Cylinder?
Selecting this 100 mm bore over the smaller 80 mm variant significantly increases thrust from 2513 N to 3927 N at 0.5 MPa, making it the preferred choice when moving heavier payloads. Conversely, if the application only requires 2182 N at 0.5 MPa, stepping down to the 63 mm bore saves valuable space and air consumption. Ensure your compressed air supply is filtered to 40 um and regulated between 0.15 and 1.0 MPa to maintain optimal performance and seal longevity.
Because this model features a 300 mm stroke, the extended rod is susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or utilize a dedicated guided cylinder for heavy off-center loads. If the machinery must hold a load vertically without continuous air pressure, the standard SAI will drift; integrate an external pilot-operated check valve or specify the SAIL lock variant. This unit serves as a direct dimensional drop-in replacement for any ISO 15552 cylinder, matching the 100 mm bore, 300 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 SAI100BX300S FAQ
At a standard 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X300-S is dimensionally interchangeable per ISO 15552 standards. It shares the exact 100 mm bore, 300 mm stroke, and mounting interface dimensions, allowing it to drop-in replace other ISO 15552 profile cylinders without modifying the machine frame.
