Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X40-30
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X40-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 40mm 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 JSIJ32X40-30
The nominal 40 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. Its hard-anodized aluminum extruded barrel keeps the overall body more compact than a same-bore ISO 15552 unit.
This double-acting double-rod unit features a 12 mm piston rod, an M10x1.25 rod-end thread, and a G1/8 port. Adjustable air cushions of 20 mm at each end absorb impact energy. Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors. Note that the cushion only decelerates the piston; a plain cylinder does not hold load on air loss, so fit an external rod lock or pilot-operated check valve if you need to prevent drift.

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

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 JSIJ32X40-30 Is Used
Clamp Position Tuning
Fine-tune the extend endpoint on-site by up to 30 mm to accommodate varying part tolerances in a small machining clamping fixture.
Compact Ejector
Fit a short-stroke ejection mechanism into a tight machine cell where the JIS profile body saves valuable space over standard ISO 15552 actuators.
Light-Duty Diverter
Adjust the push distance on a lightweight sorting diverter arm without replacing the cylinder, ensuring gentle contact with delicate components.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X40-30 the Right Cylinder?
When sizing this actuator, compare it against the neighbouring 40 mm bore, which raises the 0.5 MPa push force to 628 N if your application demands more thrust. Conversely, the 32 mm bore sits at the low edge of the range, making it ideal for lighter duties where 345 N of pull at 0.5 MPa is sufficient. The -30 mm adjustable window is particularly useful when you want a shared spare across slight stroke variants or need on-site end-position tuning. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. For any stroke reaching 300 mm or longer, always guide the load to prevent 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 JSIJ32X40-30 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore model uses a G1/8 air port.
The nominal 40 mm stroke is the maximum extend travel. The external adjuster allows you to shorten the extend stroke on-site by up to 30 mm, giving a usable extend range of 10-40 mm. The retract end is fixed, and this stop mechanism only sets the end position rather than locking the load.
