Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X80-20
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X80-20 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 JSIJ32X80-20
The hard-anodized aluminum barrel keeps the build light without external tie rods. Air connects via a G1/8 port.
The -20 code means an external adjuster can shorten the extend stroke by up to 20 mm on site. You get a usable extend range of 60-80 mm, letting you fine-tune the end position without swapping the cylinder, while the retract end stays fixed. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor. The cushion only decelerates the piston near the ends; it will not hold a load on air loss, so add an external rod lock for vertical holding.

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 JSIJ32X80-20 Is Used
Stopper Cylinder Tuning
Fine-tune the 60-80 mm extend stop on-site by up to 20 mm to catch workpieces of slightly varying lengths without changing the cylinder.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X80-20 the Right Cylinder?
The adjustable stroke is ideal when you need on-site end-position tuning or want a shared spare across slight stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because this is a non-magnet SKU, you cannot fit position sensors; choose an -S version if you need CMSE/DMSE switches. For any stroke at or above 300 mm, always use a guide rail to prevent side-load damage to 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 JSIJ32X80-20 FAQ
At 0.5 MPa it pushes 402 N and pulls 345 N. At 0.7 MPa it pushes 563 N and pulls 483 N. The theoretical maximum force is 82 kgf at 1.0 MPa. The air port size is G1/8, and the rod end thread is M10x1.25.
The nominal 80 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 20 mm, giving a usable extend range of 60-80 mm for fine-tuning the end position. The retract end is fixed, and this stop mechanism is not a load lock.
