Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X25-20
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X25-20 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 JSIJ32X25-20
The hard-anodized aluminum barrel leaves out external rods, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit.
The -20 code defines a 20 mm shortening window, so the usable extend travel spans 5 to 25 mm while the retract end stays fixed. You get adjustable air cushions at both ends and a G1/8 port. Note that this specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor switch.

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 JSIJ32X25-20 Is Used
Short-Stroke Clamping
Dial in the exact 5 to 25 mm clamp reach on site to grip delicate parts without re-engineering the fixture.
Compact Ejector
Fit a space-constrained mold ejector where the short JIS profile body saves valuable machine real estate.
Micro-Pressing
Apply a precise 241 N of safe working force to seat small bearings or pins, tuning the impact depth on the fly.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X25-20 the Right Cylinder?
The adjustable stroke shines when you need to fine-tune an end position without swapping the cylinder, or when you want a shared spare across slight stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a no-magnet SKU, you cannot fit position sensors; add the -S variant for CMSE/DMSE compatibility. Since the 25 mm stroke is very short, side-load risks are minimal, but any build exceeding 300 mm of travel requires a external guide to protect the rod.
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 JSIJ32X25-20 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 is 82 kgf at 1.0 MPa. This 32 mm bore model uses a G1/8 port.
The 25 mm nominal stroke is the maximum extend travel. The external -20 adjuster lets you shorten that extend stroke by up to 20 mm on site, giving a usable range of 5 to 25 mm. The retract end remains fixed. This mechanism only sets the end position; it does not lock the load, so you need an external rod lock or pilot-operated check valve to hold a load against air loss.
