Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X300-50
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X300-50 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 300mm 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 JSIJ32X300-50
The hard-anodized aluminum barrel makes it shorter than a same-bore ISO 15552 unit.
The external adjuster lets you shorten the extend stroke by up to 50 mm on site, giving a usable range of 250-300 mm without changing the cylinder itself. The retract end is fixed. Air connects via a G1/8 port. Note this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors without switching to an -S variant.

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 JSIJ32X300-50 Is Used
Pick-and-Place Tuning
Fine-tune the 250-300 mm extend end position on site to hit varying pick heights without swapping cylinders.
Divertor Gate Stroke Trim
Shorten the extend stroke by up to 50 mm to adjust a divertor gate's reach for different package widths.
Compact Stopper Arm
Use the JIS profile body to save space in a tight conveyor lane while setting the exact stop arm extension.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X300-50 the Right Cylinder?
Conversely, 32 mm is the low edge of the range, ideal for lighter duties. The 50 mm extend-shortening window helps standardize spares across slightly different stroke variants and allows precise end-position tuning. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 300 mm stroke is relatively long for this small bore, always use an external guide 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 JSIJ32X300-50 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 G1/8 port feeds the 12 mm rod.
The external adjuster shortens the extend stroke by up to 50 mm on site. The nominal 300 mm stroke is the maximum, so the usable extend range is 250-300 mm. The retract end is fixed, and the adjuster only sets the end position—it does not lock the load.
