Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X25-10
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X25-10 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 25mm 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 JSIJ32X25-10
The nominal 25 mm stroke represents the maximum travel, yielding a usable extend range of 15-25 mm, while the retract end remains fixed. You can fine-tune the end position without changing the cylinder itself. The extruded hard-anodized aluminium barrel omits tie rods, making the body shorter and more compact than a same-bore ISO 15552 unit.
This double-acting double-rod actuator features a 12 mm piston rod, M10x1.25 rod-end thread, and a G1/8 port. Adjustable air cushions of 20 mm at each end decelerate the payload smoothly. Because this specific SKU lacks a magnet, it cannot take a CMSE or DMSE sensor; order the -S variant if you need position detection. Note that a plain cylinder does not hold load on air loss, as the cushion only decelerates, so add 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 |

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 JSIJ32X25-10 Is Used
Clamp Position Trimming
Dial in the exact 15-25 mm clamping reach on a fixture without machining new stops, using the external adjuster to compensate for part thickness variations.
Small Parts Ejection
Eject lightweight components from a tester with a precise 20 mm tap, fine-tuning the extend end position to avoid damaging delicate surfaces.
Compact Stopper Gate
Function as a short-stroke pneumatic stopper in a tight conveyor module, benefiting from the JIS profile body that fits where larger ISO 15552 units cannot.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X25-10 the Right Cylinder?
The 10 mm adjustable-stroke window is ideal for on-site end-position tuning or keeping a shared spare across slight stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Remember that this no-magnet SKU cannot support sensing, so select the -S version if your control system requires CMSE or DMSE switches. For any stroke reaching 300 mm or more, always guide the load to prevent 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 JSIJ32X25-10 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore model uses a G1/8 air port.
The -10 code means an external stop screw allows you to shorten the extend stroke by up to 10 mm on site. The nominal 25 mm stroke is the maximum, giving a usable extend range of 15-25 mm, while the retract end remains fixed. This mechanism sets the end position and is not a load lock.
