About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-30
The AirTAC SAIJ32X180-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 150-180mm usable travel window. Delivering 402N of push force at 0.5 MPa, it uses a SUS304 stainless steel rod for superior corrosion resistance. The PT tapered port threads ensure a tight, reliable pneumatic seal.
Because the rear screw acts as a hard stop for the retract end, you can dial in the exact end position during commissioning without swapping cylinders. This adjustable-stroke design omits the FB, CA, CB, and CR mounting styles, offering a focused set of ISO 15552 mounts (Basic, FA, LB, TC, FTC, TCM1, TCM2) for streamlined machine integration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-30 Is Used
Position Fine-Tuning
Dial in the exact 150-180mm retract distance during machine commissioning to perfect part seating without machining new hard stops.
Product Changeover
Quickly adjust the end-of-stroke position by up to 30mm on packaging lines when switching between slightly different product sizes.
Corrosive Assembly
Leverage the SUS304 stainless steel rod for light-duty assembly tasks in environments where moisture or mild chemicals are present.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-30 the Right Cylinder?
Choose this 32mm bore when you need precise retract positioning that a fixed-stroke SAI cannot provide, delivering 402N push and 345N pull at 0.5 MPa. If your application requires greater thrust, stepping up to the 40mm bore yields 628N push force. The adjuster is a travel stop, not a lock; it will not hold the load without live air, so use a SAIL or BSAI cylinder for positive load-holding.
To match this ISO 15552 replacement exactly, specify a 32mm bore, 180mm nominal stroke, 30mm adjustment range, PT port threads, SUS304 (B) rod material, and no magnet. Since the 180mm stroke is relatively short for this bore, side-load stress is minimal, but an external guide is still recommended for heavy off-center loads.
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 SAIJ32BX180-30 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 180mm down to 150mm. It only sets the travel end and does not lock the load without continuous air pressure.
