Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X20-20
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X20-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 20mm 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 JSIJ32X20-20
Its hard-anodized aluminum extruded barrel is shorter than a same-bore ISO 15552 unit, saving valuable machine space. The G1/8 port keeps air delivery proportional to the small volume.
The external adjuster lets you shorten the extend stroke on-site by up to 20 mm, meaning the 20 mm nominal stroke is simply the maximum travel. Note that this SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

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 JSIJ32X20-20 Is Used
Short-Stroke Clamping
Dials in exact jaw closure on small fixtures using the 20 mm extend adjuster, preventing delicate part deformation.
Compact Ejector
Fits into tight 32 mm bore machinery ejector stations where the shorter JIS profile saves valuable footprint space.
Positional Stop Tuning
Sets a precise mechanical end-stop for lightweight sorting gates, tweaking the extend position without changing hardware.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X20-20 the Right Cylinder?
The adjustable-stroke mechanism is perfect when you need to share a spare across stroke variants or dial in an exact end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a no-magnet SKU, you cannot fit position sensors; choose an -S variant for CMSE or DMSE switches. Side loads should be guided externally, a rule that applies to any stroke over 300 mm.
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 JSIJ32X20-20 FAQ
The air port is G1/8.
The external stop screw lets you shorten the extend stroke on-site by up to 20 mm. The nominal 20 mm stroke is the maximum travel, and the retract end remains fixed. The cushion only decelerates the piston; for a held load, use an external rod lock or pilot-operated check valve.
