About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-100S
The AirTAC SAIJ160X475-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. Its 475mm nominal stroke can be dialed back by up to 100mm, creating a precise 375-475mm usable travel window for fine-tuning retract end positions during commissioning. This made-to-order configuration features a SUS304 stainless steel rod, PT tapered ports, and an integrated magnet for position sensing.
Because the stroke extends to 475mm on a 40mm diameter rod, external guidance is recommended to prevent excessive side-loading. The rear adjuster acts strictly as a mechanical stop to set the travel end and does not hold the load without live air. For load-holding without pneumatic pressure, an external rod lock or a related SAIL pneumatic lock cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-100S Is Used
Heavy Fixture Positioning
Dial in the exact clamping reach within the 375-475mm window during machine setup to accommodate oversized workpieces without machining new stop blocks.
Product Changeover Diverter
Quickly reconfigure the retract end position on a packaging line when switching to different carton lengths, using the 100mm adjustment screw to adapt the stroke on the fly.
Large Assembly Press
Leverage the 10053N push force at 0.5 MPa to seat heavy components, fine-tuning the final bottoming position during commissioning to prevent over-travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX475-100S the Right Cylinder?
Select this 160mm bore cylinder when an application demands high thrust (10053N push at 0.5 MPa) alongside variable end-stop positioning. If you need less force, stepping down to a 125mm bore yields 6136N; if you require more, a 200mm bore provides 15708N. The adjustable stroke is ideal for product changeovers on a line, allowing you to shift the 375-475mm travel window without swapping the cylinder or adding external stops.
When replacing an ISO 15552 cylinder, verify the 160mm bore, 475mm stroke, 100mm adjustment range, PT port threads, and the -S magnet requirement. This SAIJ model supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The -S magnet pairs precisely with AirTAC CMSE reed and DMSE electronic sensors.

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 SAIJ160BX475-100S FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.7 MPa, the push force increases to 14074N.
The rear adjuster screw allows you to shorten the 475mm nominal stroke by up to 100mm, providing a usable travel window of 375-475mm. This mechanical stop fine-tunes the end position but does not lock or hold the load without continuous air pressure.
