About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-20
The AirTAC SAIJ200X230-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 20 mm of travel reduction. This yields a usable 210-230 mm stroke window, allowing you to dial in the exact retract position during commissioning without adding external stops. As the largest bore in the series, it generates massive thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa.
This SKU is configured with a SUS420J2 stainless steel rod for enhanced durability against moisture and a PT tapered port thread for a robust seal. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Remember the rear adjuster acts purely as a travel stop to fine-tune deceleration alongside the built-in air cushions, not as a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-20 Is Used
Heavy Press Tuning
Fine-tunes the end position of a high-tonnage press during setup, using the 210-230 mm window to perfect the crush depth without machining custom spacers.
Product Changeover
Adapts a heavy-duty assembly line to new product dimensions by simply turning the rear adjuster screw, saving changeover time versus replacing fixed cylinders.
Large Jig Alignment
Provides the 15708 N push force needed to seat large industrial components while allowing operators to trim the final 20 mm of travel for precise jig alignment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-20 the Right Cylinder?
Select this 200 mm bore when your application requires extreme force, stepping up significantly from the 160 mm bore which provides 10053 N push at 0.5 MPa. The adjustable 210-230 mm travel is ideal for machine changeovers where the exact end-of-stroke position varies slightly by product size, removing the need to physically swap out a fixed-stroke SAI cylinder. To match this replacement exactly, specify the 200 mm bore, 230 mm stroke, 20 mm adjustment, PT ports, and the SUS420J2 rod material.
Because the 230 mm stroke falls below the 1500 mm maximum, it remains a standard length, though any 200 mm bore cylinder carries substantial weight and requires rigid mounting. For applications needing to hold a load safely without live air pressure, a standard SAIJ is insufficient since the adjuster is only a stop; you should evaluate the SAIL air-released lock or BSAI clamp-lock series instead.

- ✓ 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 SAIJ200AX230-20 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the nominal 230 mm stroke by up to 20 mm, creating a 210-230 mm usable travel window. This stopper fine-tunes the retract end position but does not lock the load without continuous air pressure.
