Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X400-100
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X400-100 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 400mm 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 JSIJ32X400-100
Its hard-anodized aluminium barrel omits external rods, making the overall body shorter than a same-bore ISO 15552 unit. The G1/8 port keeps air flow tidy on smaller machines.
The JSIJ32X400-100 code means a 400 mm nominal extend stroke that you can shorten on-site by up to 100 mm via an external stop screw, yielding a 300-400 mm usable window without swapping the cylinder. Note this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

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 JSIJ32X400-100 Is Used
Sorter Diverter Tuning
Diverter arms on packaging lines use the 100 mm extend window to dial in the exact push distance for varying box widths without changing the cylinder.
Long-Reach Push Off
Ejecting small parts from a 400 mm deep machining chamber, using the external stop to limit the extend stroke and shorten cycle time.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X400-100 the Right Cylinder?
When sizing, the 32 mm bore sits at the low edge of the range, so if your application needs more push than the 563 N available at 0.7 MPa, step up to the 40 mm bore which yields 628 N at 0.5 MPa. Conversely, if you require less force, there is no smaller standard JSIJ size, so look at reducing pressure. The 100 mm adjustable window is ideal for sharing a single spare across several slightly different stroke variants, letting you fine-tune the extend end position mechanically on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 400 mm stroke creates a long lever arm, always use an external guide to prevent rod bending and side-load wear. Remember this non-S SKU cannot support position sensing.
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 JSIJ32X400-100 FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. The air port size is G1/8.
The nominal 400 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 100 mm, giving a usable range of 300-400 mm. The retract end remains fixed. This stop only sets the end position; it is not a load lock.
