Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-30S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X350-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 350mm 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 JSIJ32X350-30S
The external mechanism lets you shorten the forward travel by up to 30 mm, giving a usable range of 320 to 350 mm without swapping the unit. The hard-anodized aluminum extruded barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder.
This double-acting double-rod variant includes a built-in piston magnet for CMSE/DMSE sensors that drop directly into the side grooves. Air connects via a G1/8 port, and adjustable air cushions at both ends absorb end-of-stroke impacts. The retract position stays fixed while the external stop screw sets the exact extend endpoint. A plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve for held loads.

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 JSIJ32X350-30S Is Used
Precision Feeder Stops
Fine-tune the 320 to 350 mm extend endpoint on-site to dial in exact material stop positions without remounting the cylinder.
Compact Assembly Presses
Leverage the shorter JIS profile to fit a 32 mm bore press into tight cells while making 30 mm adjustments for different part heights.
Transfer Line Diverters
Use the built-in magnet for position confirmation as the diverter pushes light loads, relying on the 20 mm cushions for smooth stops.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-30S the Right Cylinder?
The adjustable stroke is ideal for sharing a spare across stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix means the magnet is present for CMSE/DMSE switches. Because the 350 mm stroke is long, always support the load with external guides to prevent rod bending and excessive side loading.
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 JSIJ32X350-30S FAQ
The theoretical maximum is 82 kgf at 1.0 MPa. The air port size is G1/8.
The nominal 350 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, yielding a usable range of 320 to 350 mm. The retract end remains fixed, and the adjuster sets the end position rather than locking the load.
