About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-100S
The AirTAC SAIJ100X350-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 250-350 mm usable travel window by trimming up to 100 mm off the 350 mm nominal stroke. Delivering 7068N of push force at 0.9 MPa, it handles heavy actuation with precision.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the rear stopper allows rapid end-position tuning during commissioning without swapping the cylinder.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-100S Is Used
Product Changeovers
Dial in exact end-stops on the fly when switching product sizes on a packaging line, utilizing the 100 mm travel window.
Machine Setup Tuning
Fine-tune the retract position during commissioning without adding external physical stops or changing the cylinder.
Heavy Forming Press
Leverage 7068N of push force for heavy stamping or forming operations requiring precise, adjustable end positions.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-100S the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore (yielding 4523N push at 0.9 MPa) is insufficient for your load, but a 125 mm bore is excessive. The 100 mm adjustment window is ideal for product-size changeovers on a production line. Because the stroke is 350 mm, use an external guide to prevent rod sag and excessive side loading.
For ISO 15552 replacement matching, specify: 100 mm bore, 350 mm stroke, 100 mm adjustment, PT tapered ports, and the -S magnet. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, select a SAIL or BSAI 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 SAIJ100 Adjustable Cylinder SAIJ100BX350-100S FAQ
At 0.9 MPa, this 100 mm bore cylinder generates 7068N of push force and 5497N of pull force. It operates at speeds between 30 and 800 mm/s.
The rear adjuster screw allows you to shorten the effective travel by up to 100 mm, creating a 250-350 mm usable window. It acts as a physical stop and does not lock the load without live air pressure.
