About the Airtac SAI100 Standard Air Cylinder SAI100AX450S
The AirTAC SAI100X450-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N push force at 0.5 MPa, this 100mm bore configuration is built to drive substantial loads through a 450mm travel distance. The extruded aluminum barrel omits traditional tie-rods, providing a smooth exterior that resists contamination and simplifies mounting.
This specific configuration includes a -S magnet for direct mounting of CMSE or DMSE sensor switches along the dual side grooves. It is equipped with a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance, and utilizes tapered PT port threads to ensure a reliable, leak-free pneumatic connection in demanding industrial environments.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX450S Is Used
Heavy Stamping Presses
Provides the high clamping force needed to secure heavy metal sheets during progressive stamping operations, utilizing the 3927 N thrust at 0.5 MPa.
Large Pallet Diverters
Drives robust routing arms on heavy-duty packaging lines, with the 450mm stroke offering ample travel to redirect large pallets onto auxiliary tracks.
Automated Assembly Lifts
Raises and lowers substantial subassembly platforms, relying on the -S magnet and CMSE switches to confirm exact upper and lower positioning.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX450S the Right Cylinder?
Selecting this 100mm bore provides significant thrust, stepping up from the 80mm bore which yields 2513 N at 0.5 MPa. If your application requires less force and faster cycling, dropping to the 80mm bore is advisable. The 450mm stroke is well within the 1500mm maximum standard stroke for this bore, but at this length, side loads become a primary concern. Long unsupported rods are susceptible to bending under lateral stress; utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear.
Because this is a double-acting cylinder, it relies on live air pressure to both extend and retract. The adjustable air cushions at both ends decelerate the piston near the stroke limits to reduce impact, but they do not lock or hold the load. If your machinery must maintain a vertical position or hold a load safely when air pressure is exhausted or the valve is centered, you must integrate an external pilot-operated check valve or specify the SAIL (air-released lock) or BSAI (clamp-lock) variant. This unit is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders with matching 100mm bore, 450mm 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.
