About the Airtac SAI100 Standard Air Cylinder SAI100BX270S
The AirTAC SAI100X270-S is a double-acting ISO 15552 profile cylinder with a 100mm bore and 270mm stroke. It delivers a robust 3927 N of push force at 0.5 MPa, making it well-suited for heavy-duty positioning and high-load automation tasks. This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for use with CMSE or DMSE reed sensors. It features tapered PT ports sized at G1/2.
Because it adheres strictly to the ISO 15552 mounting interface, this profile cylinder serves as a drop-in replacement for other ISO 15552 cylinders without requiring bracket modifications. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. For applications requiring multi-directional clamping or dual-end positioning, the related SAID double-rod series offers an extended tooling footprint.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX270S Is Used
Heavy-Duty Pressing
Ideal for applying high downward force, such as pressing bearings into heavy housings or forming thick metal components, utilizing its 3927 N push force at 0.5 MPa.
Pallet Diverting
Provides the robust thrust needed to redirect heavy loaded pallets on conveyor lines, with the 270mm stroke offering sufficient travel to clear the transport path.
Automated Clamping
Secures large workpieces during CNC machining or welding operations, using the integrated magnet to confirm clamp engagement before the cycle begins.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX270S the Right Cylinder?
Select this 100mm bore when a smaller 80mm unit (providing 2513 N push at 0.5 MPa) lacks the thrust to move your load, but you want to avoid stepping up to a 125mm cylinder which demands 6136 N of force and larger valves. The 270mm stroke provides ample travel for mid-range actuation. Since the stroke is under 300mm, standard bearing loads are acceptable, but always verify side-load limits to prevent premature seal wear.
This standard SAI100X270-S relies on adjustable air cushions at both ends to decelerate the piston near stroke end. It does not hold a load if air pressure drops or the valve centers; the piston will drift. If your fixture must maintain vertical position without live pressure, specify the SAIL air-released lock variant or use an external pilot-operated check valve. Ensure your mounting setup matches ISO 15552 accessories like FA flanges or TC trunnions, and specify the -S magnet if you need position feedback.

- ✓ 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 SAI100BX270S FAQ
At a standard 0.5 MPa operating pressure, the SAI100X270-S 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 SAI100X270-S is dimensionally interchangeable per ISO 15552 standards. You can use it as a drop-in replacement for other ISO 15552 profile cylinders, matching the exact bore, stroke, and G1/2 port locations.
