Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X50-30
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X50-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 50mm 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 JSIJ32X50-30
Its extruded hard-anodized aluminium barrel makes it shorter than a same-bore ISO 15552 unit, and the G1/8 port keeps air plumbing neat. The external adjuster lets you shorten the extend stroke by up to 30 mm right at the machine, so the usable forward travel spans 20 to 50 mm while the retract end stays fixed.
Because the nominal 50 mm stroke acts as the maximum, you can fine-tune the forward stop without swapping the whole actuator. Note that this plain SKU has no magnet and cannot take a CMSE or DMSE sensor; add the -S variant if you need position detection. The air cushion only decelerates the piston near the ends, so fit an external rod lock or pilot-operated check valve if the load must hold on air loss.

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 JSIJ32X50-30 Is Used
Probe Contact Tuning
Dial in the extend stroke from 50 mm down to 20 mm via the external stop screw to set exact test-probe contact depth without machining new hard stops.
Small Part Ejection
Fine-tune the ejection forward position on-site to accommodate varying product sizes while relying on the 345 N pull force for a safe retract.
Compact Clamping
Leverage the shorter-than-ISO-15552 JIS profile barrel to fit clamping actuation into dense tooling arrays, adjusting the clamp reach by up to 30 mm.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X50-30 the Right Cylinder?
The -30 mm adjustable window shines when you need to dial in a precise end position on-site or want a single shared spare across several 20 to 50 mm stroke variants. Mounting options include FA, LB, TC, TCM1 and TCM2 brackets. Since this is a non-magnet SKU, it cannot host a CMSE or DMSE switch; choose the -S version for sensing. For any stroke at or above 300 mm, always guide the load to prevent rod 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 JSIJ32X50-30 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. It uses a 12 mm rod, an M10x1.25 rod thread, a G1/8 port, and a 20 mm adjustable air cushion at each end.
The external stop screw lets you shorten the extend stroke by up to 30 mm on-site, making the usable forward travel 20 to 50 mm. The nominal 50 mm stroke is the maximum, and the retract end remains fixed. This mechanism only sets the end position; it does not lock or hold the load.
