About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-10S
The AirTAC SAIJ100X475-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 465 to 475 mm. Delivering a robust 3927 N of push force at 0.5 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and features an integrated magnet for position sensing. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This model utilizes a PT tapered port thread and supports a speed range of 30-800 mm/s. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not lock the load without live air pressure. For applications requiring position holding, external pilot-operated check valves or related lock cylinders like SAIL or BSAI are necessary.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-10S Is Used
Precision End-Stop Tuning
Dial in the exact 465 to 475 mm retraction point during machine commissioning to perfect product placement without adding external physical stops.
Product Changeover
Quickly adjust the stroke by up to 10 mm on a packaging line to accommodate varying carton sizes while maintaining 3927 N of pushing force.
Corrosive Assembly Stations
Leverage the SUS304 stainless steel rod for robust actuation in washdown or mildly corrosive manufacturing environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-10S the Right Cylinder?
Choose this 100 mm bore when substantial thrust is required, stepping up from a 80 mm bore that yields 2513 N push force at 0.5 MPa. The 10 mm adjustment range is ideal for dialing in exact end-stops during machine setup or product changeovers without swapping out the entire cylinder. Because the stroke extends to 475 mm, an external guide is recommended to prevent excessive side-loading on the rod.
When matching an ISO 15552 replacement, verify the 100 mm bore, 475 mm nominal stroke, 10 mm adjuster, PT port thread, and the -S magnet option. This SAIJ variant supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR mounts. The integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state 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 SAIJ100 Adjustable Cylinder SAIJ100BX475-10S FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear mechanical stopper allows you to trim the effective travel back by up to 10 mm, creating a 465 to 475 mm usable window. It functions only as a travel stop and does not hold the load without continuous air pressure.
