Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-50
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X350-50 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 JSIJ32X350-50
Its external stop screw provides a 50 mm window to shorten the extend stroke on site, letting you dial in the exact extend end from 300 to 350 mm without swapping the actuator. The retract end remains fixed. This compact aluminum profile body is notably shorter than an ISO 15552 cylinder of the same bore, saving valuable machine space.
It features a 12 mm rod, an M10x1.25 rod-end thread, and a G1/8 port. Adjustable air cushions of 20 mm at each end absorb impact. Because this specific SKU lacks a magnet, it cannot take a CMSE or DMSE sensor. Note that the cushion only decelerates the piston; it does not hold the load on air loss, so fit an external rod lock or pilot-operated check valve for suspended 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 JSIJ32X350-50 Is Used
Adjustable Stop Positioning
Dial in the exact extend end point from 300 to 350 mm on site using the external 50 mm adjuster window, perfect for testing multiple part lengths without changing cylinders.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-50 the Right Cylinder?
The 50 mm adjustable window is highly useful when you need to fine-tune a final end position across multiple stations or share a spare actuator across slightly different stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the 350 mm stroke creates a long lever arm, always use an external guide rail to prevent rod bending and side-load damage. To add position sensing, you must select the -S magnet variant for CMSE or DMSE switches, as this base SKU cannot accept them.
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 JSIJ32X350-50 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore model uses a G1/8 air port.
The nominal 350 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke by up to 50 mm on site, giving a usable extend range of 300 to 350 mm. The retract end is fixed, and this stop mechanism only sets the end position; it does not lock the load.
