Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-20
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X350-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 350mm stroke, G1/8 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-20
The hard-anodized aluminium barrel keeps the frame clean while providing a 350 mm extend stroke that can be fine-tuned down by 20 mm on-site. A G1/8 port feeds the double-acting double-rod system, and the external adjuster lets you set the exact end position without swapping the whole cylinder. The retract end remains fixed, and the adjustable air cushions absorb 20 mm of impact at each end.
Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors for position detection. Furthermore, the adjustable stop screw only sets the end position; it is not a load lock. If your application requires the load to be held securely on air loss, you must fit an external rod lock or a pilot-operated check valve, as the cushion solely decelerates the piston near the stroke ends.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |

| Max (@1.0 MPa) | 70 kgf | |
JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-20 Is Used
Gauge Position Trimming
Use the 20 mm extend window to dial in the exact contact point of a gauging station without shimming or changing the cylinder mount.
Transfer Stopper Tuning
Adjust the stopper block position on-site to accommodate varying product lengths on a packaging line while using the full 350 mm reach.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-20 the Right Cylinder?
Conversely, if you need finer resolution in a lighter setup, this bore is optimal. The -20 mm adjustable window is particularly useful when you want a shared spare across slightly different stroke variants or need to fine-tune the extend end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Note that at 350 mm of stroke, you should always guide the load externally to prevent rod bending and side-load damage.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ 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 Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-20 FAQ
This 32 mm bore cylinder uses a G1/8 port.
The nominal 350 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 20 mm on-site, giving a usable extend range of 330-350 mm. The retract end is fixed, and this stop only sets position rather than locking the load.
