About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-10S
The AirTAC SAIJ200X140-10-S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty motion control. It features a rear mechanical adjuster that permits up to 10 mm of stroke reduction, creating a precise 130-140 mm usable travel window for exact end-position calibration. In the 200 mm bore class, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it suitable for high-thrust industrial operations.
This variant is equipped with a SUS420J2 stainless steel piston rod (option A) for enhanced corrosion resistance and durability. The extruded aluminum barrel includes sensor grooves on both sides, and because this unit includes a magnet (-S), it directly supports AirTAC CMSE reed and DMSE solid-state electronic switches for position feedback. The rear stopper allows you to dial in the retract distance during commissioning without adding external physical stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 130-140 mm retract distance during heavy press setup to accommodate material thickness variations without external stops.
Machine Changeover
Quickly adjust the end-of-stroke position on a 15708 N actuator when switching product sizes on a high-thrust production line.
Automated Assembly End Stops
Use the rear screw to set precise bottoming positions for heavy assembly tooling, leveraging the robust SUS420J2 rod under high load.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX140-10S the Right Cylinder?
Select this 200 mm bore cylinder when an application demands substantial thrust—15708 N at 0.5 MPa—and requires exacting end-position tuning. If you need slightly less force, stepping down to a 160 mm bore yields 10053 N of push force, whereas moving up is impossible within this series as 200 mm is the largest standard size. The adjustable 130-140 mm travel window is ideal for machine setups requiring variable end stops without swapping hardware. Fluid supply connects via PT G3/4 ports. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. For applications requiring the load to be held mechanically without continuous air pressure, note that the rear adjuster functions strictly as a travel stop, not a lock; you should instead evaluate the SAIL air-released lock or BSAI clamp-lock 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 SAIJ200 Adjustable Cylinder SAIJ200AX140-10S 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 deliver up to 21991 N of push force at 0.7 MPa.
The rear adjuster screw allows you to shorten the nominal 140 mm stroke by up to 10 mm, providing a usable travel window of 130 to 140 mm. This enables fine-tuning of the end position at commissioning without modifying the cylinder mount.
