About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX240-10
The AirTAC SAIJ50X240-10 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 240 mm nominal stroke that can be fine-tuned down by up to 10 mm, creating a precise 230-240 mm usable travel window for commissioning without external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the piston rod utilizes a SUS420J2 stainless steel material (code A) for enhanced corrosion resistance.
Delivering 982 N of push force and 825 N of pull force at 0.5 MPa, this 50 mm bore actuator operates at speeds between 30 and 800 mm/s. It features PT tapered port threads (G1/4), a 20 mm rod diameter with an M16x1.5 thread, and variable air cushions at both ends to decelerate the load smoothly. The rear adjuster acts strictly as a travel stop to set the end position, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX240-10 Is Used
End-Position Tuning
Dial in the exact 230 to 240 mm retract distance during machine commissioning to compensate for mechanical tolerances without swapping cylinders.
Product Changeover
Quickly adjust the stroke stop by up to 10 mm on packaging lines when running slightly shorter product lengths, minimizing downtime.
Machining Fixtures
Utilize the SUS420J2 stainless steel rod in clamping fixtures where precise travel limits and moderate corrosion resistance are required.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX240-10 the Right Cylinder?
Choose this 50 mm bore cylinder when you need 982 N of thrust at 0.5 MPa and require minor in-field end-position tuning, stepping up from a 40 mm bore (628 N push) or down from a 63 mm bore (1559 N push). An adjustable stroke is preferred over a fixed SAI model when accommodating slight mechanical variances or product changeovers. To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 240 mm stroke, 10 mm adjustment range, PT port thread, and desired mounting style from the available Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. Because the 240 mm stroke is substantial, ensure adequate external guiding to prevent excessive side-loading on the rod.
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 SAIJ50AX240-10 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. At 0.7 MPa, the push force increases to 1374 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke within a 230-240 mm window. It only sets the travel end-point and does not lock the load without continuous air pressure.
