About the Airtac SAI100 Standard Air Cylinder SAI100BX450S
The AirTAC SAI100X450-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Operating at 0.5 MPa, it generates 3927 N of push force and 3681 N of pull force, scaling up to 5497 N at 0.7 MPa. The 450 mm stroke provides the extended travel distance required for large-format material handling and automated assembly lines.
Built to exacting standards, this specific configuration incorporates a SUS304 stainless steel rod (material code B) for superior corrosion resistance in wet or washdown environments. The -S suffix indicates an integrated magnet for non-contact position sensing, which pairs seamlessly with CMSE or DMSE switches fitted into the dual sensor grooves along the extruded aluminum barrel. Fluid connections use PT tapered threads.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX450S Is Used
Automotive Body Welding
Handles large stamping panels and positions heavy structural components on welding lines, utilizing the SUS304 rod to withstand harsh manufacturing environments.
Pallet Diverting
Actuates heavy-duty diverters on high-throughput packaging conveyors, relying on the 3927 N push force at 0.5 MPa to shift loaded pallets smoothly.
Large Press Feeding
Feeds heavy sheet metal blanks into large mechanical presses, where the 450 mm stroke accommodates deep feed requirements and the adjustable cushions absorb high kinetic energy.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX450S the Right Cylinder?
Selecting this 100 mm bore cylinder is appropriate when application force requirements exceed the 2513 N push capacity of the 80 mm variant at 0.5 MPa, but do not justify stepping up to the 125 mm bore which delivers 6136 N. The 450 mm stroke falls safely within the 1500 mm maximum standard stroke limit for this bore size, ensuring standard production availability.
Because the 450 mm stroke creates a long unsupported rod extension, careful attention to mounting is required to prevent rod-bearing bending under side loads. Utilizing external guide rails or a fully guided cylinder carriage is strongly recommended for this travel length. Note that the adjustable air cushions at both stroke ends decelerate the piston to prevent impact damage, but they do not lock the rod; if the load must be held without continuous air pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. For drop-in replacements, match the 100 mm bore, 450 mm stroke, G1/2 port, and required mounting accessories (such as FA/FB flanges or TC trunnions) per the ISO 15552 interface.
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 SAI100BX450S FAQ
At 0.5 MPa, the SAI100X450-S provides 3927 N of push force and 3681 N of pull force. When operating pressure increases to 0.7 MPa, the push force scales to 5497 N.
Yes, the SAI100X450-S is dimensionally interchangeable per ISO 15552. You can replace other ISO 15552 profile cylinders by matching the 100 mm bore, 450 mm stroke, G1/2 port, and mounting interface.
