About the Airtac SAI40 Standard Air Cylinder SAI40BX450
The AirTAC SAI40X450 is a double-acting ISO 15552 profile cylinder engineered to deliver 628N of push force at 0.5MPa. Its 450mm stroke provides the extended travel needed for material handling and automated clamping tasks. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that resists mechanical debris buildup.
Built for demanding environments, this specific configuration utilizes a SUS304 stainless steel piston rod for superior corrosion resistance. It features PT tapered port threads and lacks a standard magnet, making it ideal for applications where external reed switches are not required. The standardized ISO 15552 mounting interface ensures seamless integration into existing global machinery setups.

Where the Airtac SAI40 Standard Air Cylinder SAI40BX450 Is Used
Extended Transfer Push
Pushes products between conveyor lanes over a 450mm gap, utilizing the 628N thrust to move packaged goods reliably without stalling.
Remote Actuation Gate
Operates safety guarding or process gates at a distance, where the SUS304 rod provides excellent moisture and washdown resistance.
Vertical Lift Elevator
Lifts lightweight tote bins in a vertical elevator system, taking advantage of the ISO 15552 mounting footprint for easy frame integration.
Is the Airtac SAI40 Standard Air Cylinder SAI40BX450 the Right Cylinder?
Choose this 40mm bore when a 32mm bore (402N at 0.5MPa) lacks sufficient thrust, but a 50mm bore (982N at 0.5MPa) would be physically oversized. The 450mm stroke pushes the cylinder into a length where side-load management becomes critical. An unsupported rod of this length is prone to bending under lateral forces; utilizing an external guide rail or a dedicated guided cylinder is highly recommended to prevent premature rod-bearing wear.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 units of matching bore and stroke. It uses a G1/4 port, an M12x1.25 rod thread, and accepts standard FA/FB flange or LB foot mounting accessories. Note that the adjustable air cushions only decelerate the piston at stroke ends; they do not hold a load. If position holding upon air loss is required, select the SAIL locking variant or use an external pilot-operated check valve.
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 SAI40 Standard Air Cylinder SAI40BX450 FAQ
At 0.5MPa operating pressure, the SAI40X450 provides a push force of 628N and a pull force of 528N. It can reach a maximum push force of 1130N at 0.9MPa.
Yes, the SAI40X450 is dimensionally interchangeable per ISO 15552. You can drop it into existing machinery to replace other ISO 15552 profile cylinders of the same 40mm bore and 450mm stroke.
