Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-50S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X350-50S 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 JSIJ32X350-50S
The nominal 350 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. Its hard-anodized aluminum extruded barrel omits tie rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 unit. The G1/8 port keeps air routing tight, and the built-in magnet supports CMSE/DMSE sensors.
The retract end is fixed, while the front stop screw sets the extend window down to 300 mm. Remember that the adjustable air cushions only decelerate the piston near the ends; a plain cylinder cannot hold a load on air loss, so fit an external rod lock or pilot-operated check valve if you need drift prevention.

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 JSIJ32X350-50S Is Used
Pick-and-Place Tuning
Dial in the exact extend reach on a small parts handler by turning the stop screw to shorten the 350 mm stroke by up to 50 mm, ensuring precise placement without remounting the actuator.
Sorting Diverter
Adjust the pusher extension on the fly to accommodate different package sizes on a line, using the G1/8 ported compact JIS body to save valuable machine footprint.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-50S the Right Cylinder?
When sizing, step up to a 40 mm bore if the 32 mm thrust feels marginal, or drop down if your payload is extremely light. The 50 mm adjuster window is ideal for sharing a single spare cylinder across several slightly different stroke variants, as you can tune the extend end position on the floor. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix means a magnet is already integrated for CMSE/DMSE switches. Because the 350 mm stroke is relatively long for this small bore, always use an external guide rail to prevent rod bending and absorb side loads.
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 JSIJ32X350-50S FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore model uses a G1/8 air port.
The external stop screw lets you shorten the extend stroke on site by up to 50 mm. The nominal 350 mm travel is the maximum, so your usable extend range is 300-350 mm. The retract end remains fixed, and this mechanism only sets the end position rather than locking the load.
