About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX50-30S
The AirTAC SAIJ100X50-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, letting you dial back the nominal 50 mm stroke by up to 30 mm. This creates a highly flexible 20-50 mm usable travel window for precise end-position tuning during commissioning.
This variant features a SUS420J2 stainless steel rod for superior corrosion resistance and includes a position magnet for compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the G1/2 port ensures high flow for rapid cycling.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX50-30S Is Used
Precision End-Stop Tuning
Dial in the exact retract position within the 20-50 mm window during machine commissioning without adding external mechanical stops.
Rapid Product Changeover
Quickly adjust the effective stroke length on packaging lines when handling different product sizes, reducing downtime between runs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX50-30S the Right Cylinder?
Choose this 100 mm bore when 50 mm falls short on thrust; stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. An adjustable stroke is ideal for machine setups requiring variable end stops or product changeovers without physically swapping cylinders. For a fixed stop, the standard SAI series works, but the SAIJ rear screw lets you fine-tune the retract position on the fly.
This SAIJ model uses a PT tapered port thread and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or the SAIL series. With a 50 mm stroke, side loads are minimal, but longer unsupported strokes require an external guide.
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.
