About the Airtac SAI100 Standard Air Cylinder SAI100BX180S
The AirTAC SAI100X180-S is a double-acting ISO 15552 profile cylinder built for heavy-duty automation. It delivers a robust 3927 N push force at 0.5 MPa, making it well-suited for high-thrust clamping and lifting tasks within its 180 mm stroke. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists debris buildup.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It also features an integrated magnet (-S) that operates seamlessly with CMSE and DMSE sensor switches housed in the dual-side barrel grooves. Fluid ports are PT tapered thread.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX180S Is Used
Heavy-Duty Stamping
Provides the 3927 N push force required to seat bearings or form light gauge metal sheets in automated presses.
Pallet Diverter
Uses the 180 mm stroke to push heavy pallets onto branching conveyor lanes without overwhelming the routing guide.
Parts Ejection
Leverages the SUS304 stainless steel rod to safely eject machined components from CNC enclosures exposed to cutting fluid.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX180S the Right Cylinder?
Select this 100 mm bore when a 80 mm bore (providing 2513 N at 0.5 MPa) lacks the necessary thrust, but you want to avoid stepping up to a 125 mm cylinder that demands larger valves and 6136 N worth of structural support. The 180 mm stroke provides ample travel for medium-throw actuators without requiring excessive mounting space.
Because the stroke is under 300 mm, rod-bearing bending from side loads is less pronounced than in longer units, but external guide rails should still be used for heavy off-center loads. If your application must hold a load vertically without constant air pressure, note that the standard adjustable air cushions only decelerate the piston at stroke end and do not function as a lock; you should specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead. As a dimensionally interchangeable ISO 15552 unit, it serves as a direct drop-in replacement for other ISO 15552 profile cylinders, matching the 100 mm bore, 180 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 SAI100BX180S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI series is dimensionally interchangeable per ISO 15552. You can drop it in to replace other ISO 15552 profile cylinders by matching the 100 mm bore, 180 mm stroke, and G1/2 port size.
