About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-40
The AirTAC SAIJ32X180-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 140-180 mm usable travel window by trimming the 180 mm nominal stroke up to 40 mm. Delivering 402 N of push force at 0.5 MPa, it handles light-duty positioning with precision. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet option.
Built with a SUS304 stainless steel rod (code B), it is well-suited for environments where corrosion resistance is a priority. The M10x1.25 rod thread and 12 mm rod diameter offer a compact interface, but long unsupported strokes still require an external guide to prevent side-load wear. The rear adjuster acts purely as a mechanical stop to fine-tune end positions during commissioning without adding external stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-40 Is Used
Machine Changeover
Dial back the 180 mm stroke by up to 40 mm during product size changes without replacing the cylinder or adding external stopper blocks.
End-Stop Commissioning
Fine-tune the retract end position precisely during machine setup to perfect seating against a workpiece or fixture.
Corrosive Environments
The SUS304 stainless steel rod provides reliable performance and rust resistance in testing or mildly corrosive manufacturing settings.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-40 the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N push force at 0.5 MPa and on-the-fly end-position tuning. If your setup needs greater thrust, stepping up to the 40 mm bore yields 628 N. The 40 mm adjustment range is ideal for product changeovers on a line, allowing you to dial back the stroke from 180 mm to 140 mm without swapping the cylinder. The rear screw sets the travel end and works alongside the 27 mm air cushions for deceleration, but it does not hold the load without live air. For load-holding without pressure, consider the SAIL or BSAI series. This SAIJ variant uses a PT tapered port thread and supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set, omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552.
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 SAIJ32BX180-40 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the effective travel from 180 mm down to 140 mm. This mechanical stop sets the retract end position for fine-tuning during commissioning, but it is not a lock and will not hold the load without live air pressure.
