About the Airtac SAI100 Standard Air Cylinder SAI100BX165
The AirTAC SAI100X165 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 5497 N of push force at 0.7 MPa across its 165 mm stroke, it provides the robust thrust required for high-load moulding and pressing tasks. The extruded aluminum barrel design omits tie rods, ensuring a clean exterior that resists mechanical interference.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance in washdown or chemically exposed settings. It utilizes PT tapered port threads and lacks a standard magnet. If position feedback is required for this unit, adding the -S magnet option allows seamless integration with CMSE or DMSE sensor switches fitted directly into the dual side grooves.

Where the Airtac SAI100 Standard Air Cylinder SAI100BX165 Is Used
Heavy-Duty Stamping
Provides the 5497 N force at 0.7 MPa needed to drive stamping dies and form rigid metal components securely.
Plastic Injection Unloading
Extracts large molded parts from injection machines, utilizing the SUS304 rod to withstand high-heat factory environments.
Pallet Diverting
Pushes heavy loaded pallets off high-speed material handling lines with reliable, consistent kinetic energy absorption.
Is the Airtac SAI100 Standard Air Cylinder SAI100BX165 the Right Cylinder?
Selecting this 100 mm bore makes sense when 80 mm (3518 N at 0.5 MPa) lacks the necessary push strength, but stepping up to 125 mm (8590 N at 0.5 MPa) would be physically oversized. The 165 mm stroke handles moderate travel distances efficiently. To guarantee a dimensionally exact replacement, match the 100 mm bore, 165 mm stroke, PT G1/2 port, and required mounting accessory (like an FA flange or TC trunnion).
Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though external guides are always recommended if absorbing lateral moments. Remember that the integrated adjustable air cushions only decelerate the piston near stroke ends; they do not lock the rod. If your fixture must hold position safely during a compressed air loss, specify the SAIL variant with an air-released lock or a BSAI clamp-lock cylinder.
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 SAI100BX165 FAQ
