About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX25-10S
The AirTAC SAIJ160X25-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 25 mm travel to a highly precise 15-25 mm usable window. Built with a SUS304 stainless steel rod, it is purpose-built for environments demanding corrosion resistance. Delivering a pull force of 9425 N at 0.5 MPa, it provides immense thrust for heavy-duty operations.
This adjustable-stroke model uses a PT tapered port thread and includes a magnet for seamless integration with CMSE reed and DMSE electronic sensors. The rear adjustment screw acts purely as a travel stop for end-position tuning; it does not lock or hold the load without continuous air pressure. For load-holding requirements, an external rod lock or SAIL cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX25-10S Is Used
Heavy Pressing Operations
Utilizes the 18095 N push force at 0.9 MPa for securely seating large bearings or heavy components, with the 15-25 mm travel window allowing perfect depth calibration.
Machine Commissioning
The 10 mm rear stopper allows operators to fine-tune the exact end position during line setup without physically replacing the cylinder or adding external spacers.
Corrosive Environments
The SUS304 stainless steel rod and optional Viton H seals make this cylinder suitable for washdown or chemical processing areas where carbon steel rods would degrade.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX25-10S the Right Cylinder?
Choose this 160 mm bore when your application requires extreme force that smaller bores cannot provide, such as shifting from an 80 mm bore that yields 2268 N pull at 0.5 MPa. The 10 mm adjustment range is ideal for fine-tuning the exact end-of-stroke position during machine commissioning or product changeover, eliminating the need to swap cylinders or bolt on external stops. Because the nominal stroke is only 25 mm, side-load risks are minimal, but the robust 40 mm rod and M36x2 thread handle high stress effortlessly.
When matching ISO 15552 dimensions, specify the 160 mm bore, 25 mm stroke, 10 mm adjustment, PT port thread, SUS304 (B) rod material, and the -S magnet. Remember that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants. If you need pure fixed-stroke motion without the rear adjuster, the standard SAI series is the direct alternative.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX25-10S FAQ
At 0.5 MPa, it provides 10053 N of push force and 9425 N of pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 18095 N.
The rear adjuster screw allows you to shorten the 25 mm nominal stroke by up to 10 mm, creating a usable travel window of 15 to 25 mm. This stopper decelerates the travel end but does not lock the load without live air pressure.
