About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-30
The AirTAC SAIJ32X230-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 200 to 230 mm, allowing you to dial back the nominal 230 mm stroke by up to 30 mm during machine commissioning. Delivering 402 N of push force at 0.5 MPa, it fits light-duty applications perfectly.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, so external solid-state or reed switches cannot be mounted directly without modification. The rear adjuster acts strictly as a mechanical stop to set the end position; it does not lock or hold the load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-30 Is Used
Machine Commissioning
Fine-tune the 200-230 mm travel window during initial setup to perfectly strike product pushers without mechanical shims.
Product Changeover
Quickly adjust the retract end-position by up to 30 mm when switching between varying package sizes on a packaging line.
Variable End Stops
Dial in the exact stopping point for delicate assembly operations where a fixed 230 mm stroke would apply too much pressure.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX230-30 the Right Cylinder?
Select this 32 mm bore when your setup requires exact end-position tuning without adding external stops or swapping cylinders. If your application needs greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. For load-holding requirements without live air, this cylinder is insufficient since the adjuster is not a lock; consider an AirTAC SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 230 mm stroke, PT port thread, and the 30 mm adjustment range. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR configurations. Since the 230 mm stroke is under the 300 mm threshold, side-load concerns are minimal, but always guide long unsupported loads properly.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAIJ32BX230-30 FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 230 mm down to 200 mm. This creates a 30 mm adjustable window for fine-tuning the retract end position at commissioning without changing the cylinder itself.
