Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-50
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 230mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-50
The AirTAC SAIJ32X230-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 32 mm bore and a 230 mm nominal stroke, but the integrated stopper screw allows you to fine-tune the effective travel down to 180 mm. This creates a 180-230 mm usable window, giving you 50 mm of end-position flexibility without needing external stops. In its standard configuration, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This specific SKU is built with an SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. Note that the rear adjuster functions strictly as a travel stop and does not lock the load; for position holding without live air pressure, consider an external rod lock or the AirTAC SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-50 Is Used
Machine Changeover
Dial in the exact 180-230 mm end-stop during product size changes on a packaging line without swapping out the entire cylinder assembly.
Fixture Alignment
Fine-tune the clamping reach on machining fixtures during initial commissioning to accommodate part tolerances and prevent over-travel.
Variable Sorting Stroke
Adjust the rejection stroke length on a conveyor system on the fly to handle different package sizes without reprogramming the motion controller.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX230-50 the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires precise end-position tuning during commissioning or frequent product-size changeovers. If your setup demands greater thrust, stepping up to the 40 mm bore increases push force to 628 N at 0.5 MPa. Conversely, if you need less force in a tighter footprint, dropping to a smaller bore is advised, though the 32 mm offers an excellent balance of compact size and 724 N maximum push force at 0.9 MPa.
Because the 230 mm stroke is relatively long for a 32 mm bore, the 12 mm rod and M10x1.25 rod thread have limited side-load capacity; always use an external guide to prevent rod binding. This model uses PT tapered ports and supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It is dimensionally interchangeable with ISO 15552 cylinders.

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 Adjustable Cylinder SAIJ32 SAIJ32AX230-50 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 724 N of push force.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 230 mm nominal stroke down to 180 mm. This provides a 180-230 mm usable window for fine-tuning the retract end position at commissioning, but it does not lock the load without live air.
