About the Airtac SAI160 Standard Cylinder SAI160BX400S
The AirTAC SAI160X400-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 provides the robust thrust required for demanding industrial pressing and lifting operations.
This specific configuration features a SUS304 stainless steel piston rod for superior corrosion resistance and includes a built-in magnet (-S) for seamless integration with CMSE or DMSE sensor switches along the dual extruded barrel grooves. It utilizes PT tapered port threads and operates reliably at speeds of 30-500 mm/s.

Where the Airtac SAI160 Standard Cylinder SAI160BX400S Is Used
Heavy Metal Stamping
Provides the 14074 N force necessary to form and stamp thick gauge sheet metal components in automated fabrication lines.
Large Assembly Pressing
Drives large industrial bearings and heavy housings into position during off-highway equipment manufacturing.
Bulk Material Diverting
Actuates heavy-duty flow control gates and diverter arms on high-capacity aggregate and mining conveyors.
Is the Airtac SAI160 Standard Cylinder SAI160BX400S the Right Cylinder?
Selecting this 160 mm bore cylinder is ideal when an application demands higher thrust than the 125 mm bore variant (which provides 8590 N push at 0.7 MPa) without stepping up to the massive 200 mm bore size. The 400 mm stroke provides substantial travel, but because it exceeds the 300 mm threshold, external guide rails or a fully guided cylinder should be employed to prevent rod-bearing bending under side loads.
As a genuine AirTAC component, it offers direct dimensional interchangeability with other ISO 15552 profile cylinders. It features a PT G3/4 port, an M36x2 rod thread, and 50 mm adjustable air cushions at both ends. Note that if the machinery requires the load to be physically held without continuous air pressure, the SAIL lock or BSAI clamp-lock variant must be used instead of relying on this standard 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 SAI160 Standard Cylinder SAI160BX400S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore double-acting cylinder generates a push force of 14074 N and a pull force of 9425 N.
No, the standard SAI cylinder relies on live air pressure and its cushions only decelerate the piston near stroke end. To hold a load safely without pressure, use the SAIL or BSAI lock variants.
