About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-20S
The AirTAC SAIJ200X180-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a massive 15708N push force at 0.5MPa and a 160-180mm usable travel window, allowing you to dial back the 180mm nominal stroke by up to 20mm during commissioning. The extruded aluminum barrel features sensor grooves on both sides for straightforward positioning.
This unit includes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and pairs with PT tapered port threads. Because it carries the -S magnet, it supports AirTAC CMSE reed and DMSE solid-state sensors for precise end-of-travel detection. The rear adjuster acts purely as a mechanical stop to fine-tune the end position, so it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-20S Is Used
Press Stroke Tuning
Dial in the exact 160-180mm end-position during machine setup to accommodate varying material thicknesses without external stopper blocks.
Product Changeover
Quickly adjust the retract end-stop by up to 20mm when switching product sizes on the line, minimizing downtime between runs.
Heavy Forming Setup
Leverage the 15708N push force at 0.5MPa for pressing applications, using the rear screw to fine-tune the final forming depth precisely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-20S the Right Cylinder?
Choose this 200mm bore if you need the 15708N thrust class; stepping down to a 160mm bore yields 10053N at 0.5MPa, while this 200mm size provides the maximum 3204kgf at 1.0MPa. The adjustable stroke is ideal for product-size changeovers on a line, letting you shift the end-stop without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 200mm bore, 180mm stroke, 20mm adjustment, PT G3/4 port, and the -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. With a 180mm stroke, the 40mm rod and M36x2 thread handle high side loads well, but always verify external guiding if heavy lateral forces are present.
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 SAIJ200AX180-20S FAQ
The rear adjuster screw lets you shorten the 180mm nominal stroke by up to 20mm, creating a 160-180mm usable travel window. It acts as a mechanical stop to fine-tune the end position at commissioning without replacing the cylinder.
It provides 15708N of push force and 15080N of pull force at 0.5MPa. At the maximum operating pressure of 1.0MPa, it delivers up to 3204kgf of thrust for heavy-duty applications.
