About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-30
The AirTAC SAIJ200X140-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that dials back the nominal 140 mm travel by up to 30 mm, creating a precise 110-140 mm usable window. Delivering 15708 N of push force at 0.5 MPa, it is built for heavy-duty positioning. The rod is SUS420J2 stainless steel, offering superior corrosion resistance compared to standard carbon steel, and the G3/4 PT tapered ports ensure high flow capacity.
This adjustable-stroke design allows you to fine-tune the retract end position during commissioning without swapping cylinders or adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. It uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-30 Is Used
Heavy Press Tuning
Dial in the exact 110-140 mm retract position during heavy press commissioning without machining external stopper blocks.
Product Changeover
Quickly adjust the end-stop up to 30 mm to accommodate different large product sizes on the same production line.
Heavy Positioning
Leverage 15708 N of thrust at 0.5 MPa to move heavy pallets while fine-tuning the landing position at the retract end.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-30 the Right Cylinder?
Select this 200 mm bore cylinder when an application requires massive thrust (up to 15708 N at 0.5 MPa) alongside exact end-position tuning. If you need less force, stepping down to a 160 mm bore yields 10053 N of push at 0.5 MPa. Choose the SAIJ adjustable version over a fixed SAI when you need variable end-stops for product changeovers or setup compensation. Remember that the rear adjuster only sets the travel end; for load-holding without live pressure, consider an external rod lock, or use the SAIL or BSAI clamp-lock cylinder variants. To replace an ISO 15552 unit, match the 200 mm bore, 140 mm stroke, 30 mm adjustment, G3/4 PT ports, and your required mounting bracket.
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 SAIJ200 Adjustable Cylinder SAIJ200AX140-30 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a maximum thrust of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the 140 mm nominal stroke by up to 30 mm, providing a 110-140 mm usable travel window. It only sets the end position and does not lock or hold the load without continuous air pressure.
