About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-50
The AirTAC SAIJ32X325-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel by up to 50 mm. This creates a 275-325 mm usable window, allowing you to fine-tune the retract end-position during commissioning without adding external stops. It delivers 402 N of push force at 0.5 MPa and operates at speeds of 30-800 mm/s.
This SKU features a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet, so external solid-state DMSE or reed CMSE switches cannot be used. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-50 Is Used
End-Position Tuning
Dial in the exact retract distance within the 275-325 mm window during machine setup without swapping cylinders.
Product Changeover
Quickly adjust the stroke stop on the production line when switching to a different package or part size.
Light Assembly
Provides 402 N of push force at 0.5 MPa for precise light-duty pressing and indexing tasks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX325-50 the Right Cylinder?
Choose this 32 mm bore when 402 N of push force at 0.5 MPa is sufficient; step up to the 40 mm bore if you need 628 N to overcome higher friction. An adjustable stroke is preferred over a fixed SAI when a machine requires variable end-stops for product changeovers. To replace this cylinder, match the 32 mm bore, 325 mm stroke, 50 mm adjustment, PT ports, and SUS304 rod.
Because the 325 mm stroke exceeds the standard 1000 mm limit for this bore, it is built to order. For any stroke of 300 mm or more, the 12 mm rod diameter is more susceptible to side loads; always use an external guide to prevent binding. If your application requires true load-holding without live air, use an external rod lock or pilot-operated check valve, as the rear adjuster is only a stop.
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 SAIJ32BX325-50 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 325 mm stroke by up to 50 mm, creating a usable travel window of 275-325 mm. It only sets the end position and does not lock the load without live air.
