Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X450-40
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X450-40 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 450mm 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 JSIJ32X450-40
The hard-anodized aluminum profile barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder.
The external adjuster lets you shorten the extend stroke by up to 40 mm, giving a usable range of 410-450 mm while the retract end stays fixed. This allows fine end-position tuning without swapping the cylinder. Air connects via a G1/8 port, and adjustable air cushions of 20 mm at each end absorb impact. Note that this SKU lacks a magnet and cannot take a CMSE/DMSE sensor.

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 JSIJ32X450-40 Is Used
Gauge Position Trimming
Dial in the exact 410-450 mm extend reach on a part gauging station without machining new hard stops.
Transfer Stroke Tuning
Fine-tune the pusher end point on a conveyor transfer to accommodate different carton lengths on the fly.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X450-40 the Right Cylinder?
The adjustable stroke is ideal for sharing one spare across multiple stroke variants or dialing in exact end positions on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a 450 mm stroke, you must support the load with external guides to prevent rod bending and side-load damage. Without a -S suffix, this cylinder cannot accept position sensors.
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 JSIJ32X450-40 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. The air port size is G1/8.
An external stop screw lets you shorten the extend stroke by up to 40 mm, giving a usable range of 410-450 mm while the retract end remains fixed. The cushion only decelerates the piston near the end of travel; it does not hold the load. For load holding on air loss, use an external rod lock or pilot-operated check valve.
