Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-30
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 200mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-30
The AirTAC SAIJ32X200-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 200 mm nominal travel by up to 30 mm. This creates a 170-200 mm usable window for fine-tuning the retract end position without swapping hardware. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
Featuring a SUS304 stainless steel rod, this model handles washdown environments better than standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, though a magnet is omitted here. The rear stopper sets the travel end, but it does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-30 Is Used
Changeover Calibration
Dial in the 170-200 mm travel window during product size changeovers to perfectly seat parts without reprogramming fixed stops.
End-Position Trimming
Trim up to 30 mm off the retract stroke at commissioning to compensate for mechanical wear or sensor drift in assembly lines.
Washdown Actuation
Leverage the SUS304 stainless steel rod for light pneumatic clamping in food or packaging machinery requiring corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-30 the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa with on-the-fly end-stop tuning. If your application requires less force, step down is not an option from the minimum 32 mm bore, but stepping up to a 40 mm bore yields 628 N push force. The adjustable stroke is ideal for machine setups requiring product changeovers, whereas a fixed SAI cylinder locks you into one exact dimension. For load-holding without continuous air, use an external pilot-operated check valve or explore the SAIL lock series.
To replace an ISO 15552 cylinder, match the 32 mm bore, 200 mm stroke, PT tapered port threads, and your mounting choice from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Because the 200 mm stroke is relatively long for this compact bore, ensure external guides support the load to prevent excessive side-loading on the 12 mm rod.
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 SAIJ32BX200-30 FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the 200 mm nominal stroke by up to 30 mm, creating a 170-200 mm travel window. It only sets the end position and does not lock the load without live air.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. The maximum force at 1.0 MPa is 82 kgf.
