Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X80-40S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X80-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 80mm 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 JSIJ32X80-40S
The nominal 80 mm stroke acts as the maximum travel, letting you fine-tune the end position without swapping the actuator. Built with a hard-anodized aluminum barrel, the body is noticeably shorter and more compact than a same-bore ISO 15552 unit. The G1/8 port keeps airflow efficient across the 30-800 mm/s speed range.
The -S suffix means a built-in piston magnet is present, allowing CMSE or DMSE sensors to drop directly into the side grooves for position detection. Remember that the adjustable stop sets the end position but does not lock the load; you will need an external rod lock or pilot-operated check valve to hold a load securely against air loss.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 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 JSIJ32X80-40S Is Used
Stopper Cylinder Tuning
Adjust the 40 mm extend window on-site to set the exact stopping point for workpieces arriving at a machining station without changing the physical cylinder.
Compact Diverter Arm
Fits into tight conveyor gaps where a shorter JIS profile body is required, using the magnetic sensor to confirm the diverted position.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X80-40S the Right Cylinder?
When sizing this actuator, compare it against the neighboring 40 mm bore, which raises the 0.5 MPa push force to 628 N if your load demands more authority. Conversely, the 32 mm bore sits at the low edge of the range, making it ideal for lighter tasks where speed and minimal footprint matter most. The adjustable stroke is perfect for sharing a single spare across multiple stroke variants or tuning a final end position on the machinery. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. Because this unit includes the -S magnet, it is fully ready for CMSE/DMSE sensors. For any stroke length of 300 mm or greater, always use a guide rail to prevent excessive side-loading on the piston rod.
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 JSIJ32X80-40S FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. The air port size is G1/8.
The nominal 80 mm stroke is the maximum travel. The external adjuster allows you to shorten the extend stroke by up to 40 mm on-site, giving a usable extend range of 40-80 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load.
