About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-50S
The AirTAC SAIJ100X230-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 180 to 230 mm, letting you dial back the nominal 230 mm stroke by up to 50 mm during commissioning. Delivering 7068 N of push force at 0.9 MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered ports.
This unit includes a magnet (-S) for CMSE reed and DMSE electronic sensors, fitting neatly into the extruded aluminum barrel grooves on both sides. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without swapping cylinders, though it does not lock the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-50S Is Used
Variable End-Stop Tuning
Dial in the exact 180 to 230 mm travel distance during machine setup to accommodate varying material thicknesses without external stopper blocks.
Product Size Changeover
Quickly adjust the retract end-position on packaging lines when switching between different product sizes, ensuring precise spacing and positioning.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for pushing heavy loads up to 7068 N in washdown or mildly corrosive industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-50S the Right Cylinder?
Choose this 100 mm bore when your application requires heavy thrust around 7068 N at 0.9 MPa; if you need less force, a 80 mm bore provides 4523 N. The adjustable stroke is ideal for variable end-stops and product-size changeovers, saving the hassle of external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a lock. To replace an ISO 15552 cylinder, match the 100 mm bore, 230 mm stroke, 50 mm adjustment, PT ports, and the -S magnet. Because the 230 mm stroke is over 300 mm, ensure you use an external guide to handle side loads.
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 SAIJ100BX230-50S FAQ
At 0.9 MPa, this 100 mm bore cylinder generates 7068 N of push force and 3681 N of pull force. It operates at speeds between 30 and 800 mm/s.
The rear adjuster screw lets you shorten the effective travel from the nominal 230 mm down to 180 mm, providing a 50 mm tuning window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air.
