About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX230-30S
The AirTAC SAIJ50X230-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 230 mm stroke that can be dialed back by up to 30 mm, yielding a precise 200-230 mm usable travel window. Delivering 982 N of push force at 0.5 MPa, it fits right into mid-range pneumatic setups.
This SKU features a SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel carries sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic switches. Unlike fixed-stroke SAI units, this adjustable variant lets you fine-tune the retract end position during commissioning without adding external stops.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX230-30S Is Used
Machine Changeover
Dial in the 200-230 mm travel window on the fly to accommodate different product lengths without physically swapping out the cylinder.
Variable End-Stop Setup
Use the rear adjuster to set exact retract positions during machine commissioning, avoiding the need for external mechanical stops.
Mid-Range Positioning
Leverage the 982 N push force and SUS420J2 rod to handle moderate clamping and positioning tasks in varied manufacturing environments.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX230-30S the Right Cylinder?
Choose this 50 mm bore when your application requires around 982 N push force (0.5 MPa) or 1374 N at 0.7 MPa. If your setup needs less force, stepping down to a 40 mm bore yields 628 N; if you need more clamping power, the 63 mm bore provides 1559 N. The built-in 30 mm adjuster is ideal for product changeovers, allowing you to shift the end-stop dynamically rather than physically swapping the cylinder.
For load-holding without continuous air pressure, note that this SAIJ rear adjuster acts strictly as a travel stop, not a lock. You will need an external pilot-operated check valve or a related SAIL (air-released lock) or BSAI (clamp-lock) cylinder. To match this exact configuration for an ISO 15552 replacement, specify: 50x230 stroke, 30 mm adjustment, PT tapered ports, SUS420J2 rod, -S magnet, and standard mounting from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ50 Adjustable Cylinder SAIJ50AX230-30S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 1374 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm from the nominal 230 mm. This creates a 200-230 mm usable travel window for fine-tuning the end position without changing the cylinder.
