Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-30S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 65mm 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 SAIJ32AX65-30S
The AirTAC SAIJ32X65-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 32mm bore and a 65mm nominal stroke, but the integrated stopper screw lets you dial the effective travel back by up to 30mm. This creates a 35-65mm usable stroke window, allowing precise end-position tuning at commissioning without swapping the hardware. The extruded aluminum barrel includes sensor grooves on both sides.
In the 32mm class, this actuator generates 563N of push force and 345N of pull force at 0.7MPa. This specific SKU is configured with an SUS420J2 stainless steel rod for enhanced corrosion resistance and a PT tapered port thread. Because it includes the -S magnet option, it is fully compatible with AirTAC CMSE reed and DMSE solid-state electronic sensors for precise position feedback. The rear adjuster acts purely as a travel stop to set deceleration and end limits, so it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-30S Is Used
Product Changeover
Dial in the 35-65mm travel window during format changes on packaging lines to accommodate varying package sizes without changing the cylinder.
Machine Setup
Fine-tune the retract end-position at commissioning using the rear stopper screw, avoiding the need to machine custom external spacers.
Variable End Stops
Adjust the effective stroke dynamically on small assembly presses where the 563N push force must bottom out at slightly different depths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX65-30S the Right Cylinder?
Choose this 32mm bore cylinder when an application requires 563N of push force at 0.7MPa and a highly variable end-stop. The 30mm adjustment range is ideal for machine setups requiring frequent product changeovers, eliminating the need to bolt on external stops or buy multiple fixed-stroke SAI cylinders. If your setup demands load-holding without continuous air pressure, this plain SAIJ cylinder will not suffice; you should look at the SAIL air-released lock or BSAI clamp-lock variants instead.
When replacing an ISO 15552 cylinder, match these exact parameters: 32mm bore, 65mm stroke, 30mm adjustment range, PT port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting the FB, CA, CB, and CR footprints. Since the 12mm rod and M10x1.25 thread carry limited side-load capacity, always guide the load externally on strokes of 300mm or more.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32AX65-30S FAQ
At 0.7MPa operating pressure, this 32mm bore cylinder generates 563N of push force and 345N of pull force. The maximum thrust is 82kgf at 1.0MPa.
The SAIJ32X65-30-S has a 65mm nominal stroke with a rear stopper that allows you to shorten the effective travel by up to 30mm. This creates a usable travel window of 35-65mm, enabling precise end-position tuning without replacing the cylinder.
