Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-100
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X400-100 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 400mm stroke, G3/8 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 JSIJ63~80 Adjustable Cylinder JSIJ63X400-100
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, meaning the usable extension range is 300 to 400 mm while the retract end stays fixed. Because the nominal 400 mm stroke is the maximum, you can fine-tune the stopping point without physically swapping the actuator. The extruded hard-anodized aluminium barrel makes the body more compact than a same-bore ISO 15552 unit.
The G3/8 port and M18x1.5 rod thread match the 63 mm bore standard, and adjustable 29 mm air cushions at both ends absorb impact energy. Note that this specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor. Furthermore, the cushion only decelerates the piston; it does not hold the load on air loss, so fit an external rod lock or pilot-operated check valve if you need strict positioning.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 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 JSIJ63~80 Adjustable Cylinder JSIJ63X400-100 Is Used
Divert Gate Tuning
Dial in the exact extend stop between 300 and 400 mm to strike a divert gate on a conveyor without changing the physical cylinder length.
Press Stroke Setup
Fine-tune the working stroke on a light assembly press, backing off the 100 mm window to prevent over-travel on delicate parts.
Shared Spare Actuator
Keep one 400 mm nominal stroke cylinder as a universal spare, shortening the extend reach on-site to cover multiple shorter 300 mm machines.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-100 the Right Cylinder?
The adjustable stroke is highly useful when you need to share one spare cylinder across several stroke variants or dial in a precise end position on the machine. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 400 mm stroke is relatively long, always use an external guide rail to prevent rod bending and side-load damage. Finally, this non-S version cannot accept a magnetic switch; you must specify an -S variant to use CMSE or DMSE sensors.
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 JSIJ63~80 Adjustable Cylinder JSIJ63X400-100 FAQ
At 0.5 MPa it pushes with 1559 N and pulls with 1402 N. At 0.7 MPa the push is 2182 N and the pull is 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa. It operates on a G3/8 port.
The nominal 400 mm stroke is the maximum extension. An external stop screw lets you shorten the extend stroke by up to 100 mm on-site, giving a usable extend range of 300 to 400 mm. The retract end is fixed, and this stop sets the end position rather than locking the load.
