Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-75S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X350-75S 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 JSIJ32X350-75S
The hard-anodized aluminum barrel omits external rods, making the overall body shorter and more compact than a same-bore ISO 15552 unit.
The external adjuster lets you trim the usable extend stroke anywhere from 275 mm up to the 350 mm maximum without swapping the cylinder, while the retract end remains fixed. A built-in magnet supports CMSE/DMSE sensors in the side grooves for position detection. Pneumatic connections use a G1/8 port, and the adjustable air cushions decelerate the piston at both ends.

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 JSIJ32X350-75S Is Used
Gauge Position Trimming
Dial in the exact extend reach from 275 to 350 mm on a test fixture without machining new spacers or changing the actuator.
Variable Pusher Stroke
Accommodate different carton widths on a packing line by turning the external stopper screw to shorten the extend endpoint on site.
Shared Spare Inventory
Keep one 350 mm actuator in maintenance stock and adjust it down by up to 75 mm to instantly replace shorter units.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-75S the Right Cylinder?
The 75 mm adjustable window is ideal for sharing one spare across multiple stroke variants or fine-tuning the extend end-position on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 350 mm stroke creates leverage, always use an external guide rail to prevent rod bending and side loads. The -S suffix means a magnet is already fitted for CMSE/DMSE switches.
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 JSIJ32X350-75S 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.
An external stop screw lets you shorten the extend stroke by up to 75 mm on site, giving a usable extend range of 275 to 350 mm. The nominal 350 mm stroke is the maximum, and the retract end is fixed. This mechanism sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve to hold a load against air loss.
