The AirTAC Airtac SAIJ50 Adjustable Cylinder SAIJ50AX230-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø50mm bore and 230mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAIJ50X230-75 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 155 to 230 mm window. This 50 mm bore generates 982 N of push force and 825 N of pull force at 0.5 MPa, making it well suited for moderate load positioning. The barrel features an extruded aluminum profile with sensor grooves on both sides for straightforward detection integration.
This specific SKU uses a SUS420J2 stainless steel rod for enhanced corrosion resistance compared to standard carbon steel. The rear stopper mechanism lets you dial in the exact end position during commissioning or product changeovers without bolting on external stops or swapping the cylinder. Remember that the adjuster acts only as a travel stop and does not hold the load without live air pressure.

Dial in the exact end-stop from 155 to 230 mm during product size changeovers on a packaging line without changing cylinder hardware.
Fine-tune the retract end position during machine commissioning to align tooling precisely within a 75 mm adjustment window.
Accommodate multiple part lengths on a single conveyor by adjusting the cylinder stroke back up to 75 mm for each new batch.
Choose this 50 mm bore when you need precise end-position tuning within a 155-230 mm travel window. If your application requires less force, stepping down to a 40 mm bore yields 628 N of push force at 0.5 MPa; if you need more clamping power, moving up to a 63 mm bore provides 1559 N. The adjustable stroke is ideal for machines running multiple product sizes, whereas a fixed-stroke SAI cylinder is better for dedicated single-purpose stations.
Because the total stroke is 230 mm, you should guide the load externally to prevent excessive side loading on the M16x1.5 rod thread. This configuration uses PT tapered ports and the reduced SAIJ mounting set, which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. For any load-holding requirements without live air pressure, select a SAIL pneumatic lock cylinder or an external rod lock instead of relying on this rear adjuster.
Quick checklist
At a standard 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. It can reach up to 1767 N of push force at 0.7 MPa.
The rear adjuster acts as an external stopper that lets you mechanically shorten the effective stroke from its 230 mm nominal length down to 155 mm. It sets the travel end position but does not lock or hold the load without continuous air pressure.
