About the Airtac SAI100 Standard Air Cylinder SAI100BX150
The AirTAC SAI100X150 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a robust push force of 3927 N and a pull force of 3681 N at 0.5 MPa, making it well-suited for high-thrust pressing and heavy load transfer over its 150 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in harsh or washdown environments. Fluid ports utilize a PT tapered thread type. For applications requiring end-of-stroke position detection, the barrel includes integrated sensor grooves on both sides, ready to accept CMSE or DMSE switches when a magnet is specified.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX150 Is Used
Heavy-Duty Pressing
Ideal for applying high downward clamping or pressing force, utilizing its 3927 N push capability at 0.5 MPa to seat bearings or form components securely.
Industrial Material Handling
Moves heavy pallets or chassis components along production lines, where the 100 mm bore provides the necessary thrust to overcome significant sliding friction.
Robotic Gripper Actuation
Drives large-scale mechanical grippers for lifting metal castings or heavy fabricated parts, relying on the SUS304 rod for durability in demanding industrial cells.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX150 the Right Cylinder?
Select this 100 mm bore when a 80 mm cylinder's 2513 N push force at 0.5 MPa is insufficient for your heavy loads. If the 150 mm stroke is longer than necessary, stepping down to a 100 mm stroke optimizes cycle time and saves space. Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though external guides are still recommended for heavy off-center loads.
This model serves as a drop-in replacement for any dimensionally interchangeable ISO 15552 cylinder, matching the 100 mm bore, 150 mm stroke, and PT port interface. Remember that the standard double-acting SAI does not hold position if air pressure is lost; for dead-load holding, consider the SAIL variant with an air-released lock or an external pilot check valve. Mounting accessories include LB foot brackets, FA flanges, and TC trunnions.
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 SAI100BX150 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides a push force of 3927 N and a pull force of 3681 N. If you increase pressure to 0.7 MPa, the push force rises to 5497 N.
Yes, the SAI100X150 is a true ISO 15552 profile cylinder. Its mounting dimensions, 100 mm bore, 150 mm stroke, and port locations are fully interchangeable with other standard ISO 15552 cylinders, allowing for direct drop-in replacement.
