About the Airtac SAI100 Standard Air Cylinder SAI100BX240
The AirTAC SAI100X240 is a double-acting profile cylinder built to ISO 15552 dimensional standards, providing a drop-in replacement for any standard 100mm bore interface. It delivers a robust 3927 N push force and 3681 N pull force at 0.5 MPa, making it suitable for moving heavy industrial payloads. The 240mm stroke is a non-standard made-to-order length, expanding the standard range to fit specialized machinery layouts.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in wash-down or chemically active environments. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE or DMSE switches, though a magnet must be specified separately to enable magnetic sensing.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX240 Is Used
Heavy Stamping Press
Provides the 3927 N push force required to actuate heavy stamping dies and form metal components reliably.
Pallet Diverting
Uses the 240mm stroke to extend and divert heavy pallets on a high-throughput packaging conveyor line.
Plastic Injection Mold
Leverages the SUS304 stainless rod to operate core pulls and ejector mechanisms in humid molding environments.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX240 the Right Cylinder?
Select this 100mm bore when 80mm (2513 N at 0.5 MPa) is insufficient for your load, but you want to avoid the larger footprint and air consumption of a 125mm cylinder. For this 240mm stroke, which exceeds the 1500mm standard maximum but is a custom intermediate length, ensure your mounting setup—such as a TC trunnion or FA flange—accounts for the unsupported rod length. Long strokes amplify side-load friction on the rod bearing; if the application involves heavy lateral forces, utilize an external guide rail or a guided cylinder to prevent premature wear.
Because this is a standard double-acting cylinder, it cannot hold a load if air pressure is lost or the control valve is centered; the piston will drift. For fail-safe load holding without live pressure, integrate the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. This unit uses a PT tapered G1/2 port and requires the -S option if magnetic sensors are needed.
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 SAI100BX240 FAQ
