About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-10S
The AirTAC SAIJ200X240-10-S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. Equipped with a rear adjusting screw, this model allows you to trim the nominal 240 mm stroke back by up to 10 mm, creating a precise 230 to 240 mm usable travel window. It delivers exceptional power, generating 15708 N of push thrust and 15080 N of pull thrust at 0.5 MPa, scaling up to 3204 kgf at 1.0 MPa.
This specific SKU features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Fluid supply is routed via PT tapered G3/4 ports, and the unit relies on 50 mm variable air cushions at both ends to decelerate the massive moving load smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 230-240 mm end-stop on a high-tonnage press to accommodate material thickness variances without swapping out the entire cylinder.
Automated Assembly Setup
Adjust the retract position during machine commissioning to perfectly seat large components, using the rear screw rather than adding external mechanical stoppers.
Product Line Changeover
Quickly shift the end-of-stroke position by up to 10 mm when transitioning a production line to a new product size, minimizing downtime.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-10S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application demands maximum thrust in the 3204 kgf range at 1.0 MPa, but still requires micro-adjustments to the retract end-position during commissioning. If your force requirements are lower, stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N, which might be sufficient and more compact. You would choose this adjustable SAIJ over a fixed-stroke SAI specifically to fine-tune the 230-240 mm travel window without adding external physical stops to your machine frame.
Because the 240 mm stroke exceeds the 300 mm threshold where side-loading becomes a critical wear factor, an external guide should be used to support the load. The rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true pneumatic locking without pressure, consider the SAIL or BSAI series. This unit is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200AX240-10S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 240 mm down to 230 mm. This provides a 230-240 mm usable window for fine-tuning the end position at commissioning without replacing the cylinder.
