About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-30S
The AirTAC SAIJ200X180-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a robust 15708 N push force at 0.5 MPa and allows you to dial back the nominal 180 mm stroke by up to 30 mm, creating a precise 150-180 mm usable travel window for product changeovers. The extruded aluminum barrel includes sensor grooves on both sides, and because this unit includes a magnet (-S), it works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches for exact end-position detection.
This model features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance compared to standard carbon steel. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position without adding external stops, while the variable air cushions at both ends manage deceleration. Note that neither the adjuster nor the cushions act as a lock; the cylinder cannot hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-30S Is Used
Heavy Press Fine-Tuning
Dial in the exact 150-180 mm end position during heavy press commissioning without swapping the entire cylinder or bolting on external mechanical stops.
Product Size Changeover
Quickly adjust the retract distance on packaging lines handling varying product sizes, using the 30 mm adjustment range to accommodate different heights.
Automated Assembly Stops
Set precise variable end-stops for large automotive component assembly, leveraging the 15708 N thrust and DMSE electronic sensors for reliable cycling.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-30S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme thrust, delivering 15708 N push and 15080 N pull at 0.5 MPa. If your force requirements are lower, stepping down to a 160 mm bore reduces the push force to 10053 N while saving physical space. The adjustable 150-180 mm travel window is ideal for machines that require variable end-stops during setup or commissioning, whereas a fixed-stroke SAI cylinder is better suited for dedicated single-task stations. For load-holding without continuous air pressure, this plain SAIJ cylinder is insufficient; consider an SAIL air-released lock, a BSAI clamp-lock, or an external pilot-operated check valve. When replacing an ISO 15552 unit, match the 200 mm bore, 180 mm stroke, 30 mm adjustment, PT G3/4 port, and -S magnet configuration. Because the stroke is 180 mm, ensure proper guiding to prevent excessive side-loading on the large 40 mm 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 SAIJ200 Adjustable Cylinder SAIJ200AX180-30S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw lets you shorten the nominal 180 mm stroke by up to 30 mm, providing a usable travel window of 150-180 mm. It functions as a mechanical stop for end-position tuning and does not lock or hold the load without live air pressure.
