About the Airtac SAI100 Standard Air Cylinder SAI100BX400
The AirTAC SAI100X400 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100 mm bore unit is tailored for applications needing substantial thrust over a 400 mm travel distance. The extruded aluminum barrel design eliminates protruding tie rods, providing a smooth exterior that simplifies mounting and accessorizing.
This specific configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh or washdown environments. Fluid ports are PT tapered threads. Because a magnet is not specified, it operates without integrated position sensing; add the -S option if your control system requires CMSE or DMSE switches to ride in the dual sensor grooves.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX400 Is Used
Heavy Stamping
Provides the high thrust required to actuate large forming presses and heavy-duty stamping machinery.
Pallet Diversion
Extends 400 mm to push heavy product pallets from a main conveyor line onto secondary packaging tracks.
Automated Welding
Moves heavy structural frames into position under a welding station, withstanding potential weld splatter.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX400 the Right Cylinder?
Selecting this 100 mm bore makes sense when 80 mm cylinders (providing 2513 N push at 0.5 MPa) lack the necessary power, but you want to avoid the bulk of a 125 mm unit. The 400 mm stroke provides ample extension for material handling, but at this length the unsupported rod is susceptible to bending under side loads. To prevent premature seal wear and rod-bearing failure, guide the load externally or utilize a dedicated guided cylinder design.
As a true ISO 15552 standard cylinder, this model serves as a drop-in dimensional replacement for other ISO 15552 profile cylinders. To match this exact configuration, specify a 100 mm bore, 400 mm stroke, PT G1/2 ports, and your required mounting accessories like FA flange or TC trunnion. Note that standard double-acting cylinders drift if air pressure is lost; if your application requires static position holding without live pressure, specify the SAIL or BSAI locking variant.
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 SAI100BX400 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 SAI100X400 is built to the ISO 15552 dimensional standard, making it fully interchangeable with other ISO 15552 profile cylinders of the same bore size. Ensure you match the G1/2 port and mounting interface.
