About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-30S
The AirTAC SAIJ32X300-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 270 to 300 mm usable travel window, allowing you to trim the effective stroke by up to 30 mm during commissioning without swapping the cylinder or adding external stops. It delivers 402 N of push force at 0.5 MPa and features a SUS420J2 stainless steel rod for improved corrosion resistance.
This model includes a magnet (-S) for position sensing and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a travel stop to fine-tune the end position and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-30S Is Used
Product Changeovers
Dial in the 270-300 mm travel window during format changes on packaging lines, avoiding the need to physically swap cylinders or bolt on new external stops.
End-Position Tuning
Fine-tune the retract end-stop at machine commissioning to achieve precise seating of 32 mm bore components without mechanical rework.
Variable End Stops
Accommodate varying package sizes on a conveyor sorting system by adjusting the rear stopper within the 30 mm trim range on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX300-30S the Right Cylinder?
Choose this 32 mm bore when your application requires up to 402 N of push force at 0.5 MPa (or 563 N at 0.7 MPa) alongside a 300 mm nominal stroke. If your setup demands less force, stepping down is not an option in the SAIJ range, but stepping up to a 40 mm bore yields 628 N at 0.5 MPa if you need higher thrust margins. The adjustable stroke is perfect for product changeovers on a line, letting you dial in the 270-300 mm travel window on the fly instead of machining hard stops.
Because this cylinder features a 300 mm stroke, the 12 mm rod diameter requires external guidance to prevent excessive side-loading and premature seal wear. For load-holding without continuous air pressure, this plain SAIJ adjuster will not suffice; you should explore an AirTAC SAIL pneumatic lock or an external rod lock. This SKU is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ32AX300-30S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 563 N.
The rear adjuster acts as a mechanical stop that lets you shorten the 300 mm nominal stroke by up to 30 mm, creating a 270 to 300 mm usable travel window. It only sets the end position and does not lock or hold the load without live air pressure.
