Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X40-20
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X40-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 40mm 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 JSIJ63X40-20
It is shorter than a same-bore ISO 15552 unit and features a hard-anodized aluminum barrel.
The -20 code defines an external adjuster that shortens the extend stroke by up to 20 mm on site. Nominal travel is 40 mm maximum, yielding a usable 20-40 mm window for fine-tuning the end position without swapping the cylinder. This SKU lacks a magnet and cannot take a sensor.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |

| Max (@1.0 MPa) | 286 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 JSIJ63~80 Adjustable Cylinder JSIJ63X40-20 Is Used
Clamp Stroke Tuning
Dial in the exact 20 to 40 mm extend reach on-site to accommodate varying part thicknesses without changing the cylinder.
Transfer Diverter
Adjust the extend stop externally to set the precise pusher distance for routing different box sizes on a packaging line.
Shared Spare Stock
Keep one cylinder as a universal spare and shorten the 40 mm nominal stroke on-site to fit multiple shorter-stroke machines.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X40-20 the Right Cylinder?
The on-site extend adjuster is ideal when you need to share a spare across slight stroke variants or dial in a final position. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a non-magnetized SKU, it cannot accept CMSE or DMSE switches. Side loads should be guided externally.
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 JSIJ63X40-20 FAQ
At 0.5 MPa it pushes 1559 N and pulls 1402 N. At 0.7 MPa it pushes 2182 N and pulls 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port.
The external adjuster lets you shorten the extend stroke by up to 20 mm on site. The nominal 40 mm stroke is the maximum, giving a usable extend range of 20 to 40 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
