About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-30S
The AirTAC SAIJ200X275-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 275 mm stroke that can be dialed back by up to 30 mm, creating a precise 245 to 275 mm usable travel window for exact end-position tuning during commissioning. In the 200 mm bore class, it generates a substantial 15708 N of push force and 15080 N of pull force at 0.5 MPa.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet for electronic DMSE solid-state or reed CMSE position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, and fluid is supplied through PT (tapered) G3/4 ports. The rear adjuster functions purely as a travel stop to fine-tune deceleration, not as a load lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-30S Is Used
Heavy Press End-Stop Tuning
Dial in the exact 245-275 mm travel window on heavy assembly presses during setup, using the rear stopper to compensate for mechanical deflection without changing the cylinder.
Product Size Changeover
Adjust the retract end-position on the fly when switching between different pallet or product sizes on a high-thrust conveyor handling line.
Large Mold Positioning
Fine-tune the closing end-position of large molds or heavy fixtures, leveraging the 15708 N push force and 30 mm trim range for precise alignment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX275-30S the Right Cylinder?
Selecting this 200 mm bore model is appropriate when your application requires extreme thrust, such as 15708 N push at 0.5 MPa, stepping up from a 160 mm bore that provides 10053 N. The 30 mm adjustment range is ideal for variable end-stops or product-size changeovers, allowing you to fine-tune the travel window without swapping the cylinder or adding external stops. If your process demands holding the load without live air pressure, this plain SAIJ cylinder is insufficient; you should look at the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
Because the 275 mm stroke exceeds the 300 mm threshold where side-load risks increase, an external guide is recommended to support the heavy 40 mm rod and prevent uneven seal wear. This cylinder is dimensionally interchangeable per ISO 15552, utilizing a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omitting FB, CA, CB, and CR mounts. It operates at speeds of 30-500 mm/s.

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 SAIJ200AX275-30S FAQ
It features a rear adjusting screw that allows you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 245 to 275 mm, letting you fine-tune the end position at commissioning without adding external stops.
At 0.5 MPa operating pressure, it 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.
