About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX110-40S
The AirTAC SAIJ50X110-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 982N push force at 0.5 MPa and incorporates a SUS420J2 stainless steel rod (code A) for superior corrosion resistance. The built-in magnet enables position sensing with CMSE reed and DMSE electronic switches.
Equipped with a 40mm adjustment range, this model transforms the 110mm nominal stroke into a 70-110mm usable travel window. This external stopper allows precise end-position tuning at commissioning without swapping cylinders. It features PT tapered ports and dual-side sensor grooves on the extruded aluminum barrel.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX110-40S Is Used
Product Changeover
Dial in the 70-110mm travel window during format size changes on packaging lines without physically swapping the actuator.
Commissioning Calibration
Fine-tune the retract end-position precisely during machine setup to avoid crushing delicate parts.
Variable End Stops
Establish multiple fixed end-positions on a single fixture by adjusting the 40mm stopper screw between cycles.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX110-40S the Right Cylinder?
Select this 50mm bore when an application requires 982N push force at 0.5 MPa, or step down to a 40mm bore for 628N if the load is lighter. An adjustable stroke is chosen over a fixed SAI cylinder when setups demand variable end-stops or rapid product-size changeovers. For strokes of 300mm or longer, external guides are recommended to manage side loads.
When matching ISO 15552 dimensions for a replacement, verify the 50mm bore, 110mm stroke, 40mm adjustment, PT port thread, and the -S magnet. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true pneumatic locking, consider the SAIL or BSAI series.
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 SAIJ50 Adjustable Cylinder SAIJ50AX110-40S FAQ
At a 0.5 MPa operating pressure, this 50mm bore cylinder provides 982N of push force and 825N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 200 kgf.
The rear adjuster screw shortens the 110mm nominal stroke, creating a 70-110mm usable travel window. This stopper only sets the end-position and deceleration; it does not lock or hold the load without continuous air pressure.
