About the Airtac SAI160 Standard Cylinder SAI160BX155S
The AirTAC SAI160X155-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial push force of 14074 N at 0.7 MPa, this 160 mm bore unit is built to move massive loads reliably. The 155 mm stroke provides robust extension for demanding industrial cycles.
This configuration includes a -S magnet for direct compatibility with CMSE and DMSE sensor switches, fitting neatly into the dual-side grooves of the extruded aluminum barrel. Furthermore, it is equipped with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. Operating speed is rated at 30-500 mm/s, managed by adjustable air cushions at both ends.

Where the Airtac SAI160 Standard Cylinder SAI160BX155S Is Used
Heavy Stamping
Provides the 14074 N thrust at 0.7 MPa needed to actuate large presses and form rigid metal components securely.
Injection Molding
Handles heavy core pulling and mold ejection tasks where the SUS304 rod offers excellent durability against residual moisture.
Pallet Diversion
Shifts fully loaded pallets on high-capacity assembly lines, utilizing the 155 mm stroke to clear the transport path quickly.
Is the Airtac SAI160 Standard Cylinder SAI160BX155S the Right Cylinder?
Select this 160 mm bore cylinder when an 80 mm bore cannot supply the required thrust; stepping up from 80 mm increases your 0.5 MPa push force from 2513 N to 10053 N. If you need less force, consider the 125 mm bore which yields 6136 N at 0.5 MPa. The 155 mm stroke is well below the 300 mm side-load threshold, but always ensure axial load alignment to maximize rod bearing life.
Because it adheres strictly to ISO 15552 mounting dimensions, this profile cylinder serves as a direct replacement for other ISO 15552 units. You can pair it with FA flanges or TC trunnion mounts. Note that standard SAI cylinders rely on air pressure to hold position; if your application requires static load holding upon air loss, specify the SAIL lock or BSAI clamp-lock variant instead of relying on the cushion.
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.
