About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-100
The AirTAC SAIJ160X475-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 375 to 475 mm. Belonging to the 160 mm bore class, it outputs 10053 N of push force and 9425 N of pull force at 0.5 MPa, making it suitable for heavy-duty positioning. This specific configuration features a SUS304 stainless steel rod (code B) and PT tapered ports.
Because the nominal 475 mm stroke is substantial, the 40 mm diameter rod and M36x2 thread provide necessary rigidity, though an external guide is recommended to manage side loads. The rear adjuster acts purely as a travel stop to fine-tune the retract position during commissioning; it is not a lock. For load-holding without live air pressure, an external rod lock or a related SAIL pneumatic lock cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-100 Is Used
Heavy Machinery Changeover
Dial in the 375 to 475 mm retract position during product size changeovers without fabricating new external stopper blocks.
Large Press Positioning
Leverage the 10053 N push force at 0.5 MPa to move heavy platens, using the rear stopper to fine-tune the final resting position.
Commissioning Calibration
Trim the effective stroke by up to 100 mm during initial machine setup to perfectly synchronize endpoints with tooling.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-100 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires high thrust, such as 10053 N at 0.5 MPa, alongside precise end-position tuning without swapping physical stops. If your force requirements are lower, stepping down to a 125 mm bore yields 6136 N of push force at 0.5 MPa, whereas moving up to a 200 mm bore provides 15708 N. The adjustable 100 mm window is ideal for product changeovers on large machinery.
To match this ISO 15552 interchangeable cylinder, confirm the 475 mm stroke, 100 mm adjustment range, PT port threads, and SUS304 rod material. Note that SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. Since the stroke exceeds 300 mm, ensure external guiding is in place to prevent excessive rod side-loading.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX475-100 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
The rear adjuster screw allows you to shorten the nominal 475 mm stroke by up to 100 mm, creating a usable travel window of 375 to 475 mm. The adjuster functions as a mechanical stop and does not hold the load without live air pressure.
