Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-30
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X400-30 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 JSIJ63X400-30
The hard-anodized aluminum profile barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 cylinder, while the G3/8 port feeds the 20 mm rod for a 30-800 mm/s operating speed.
The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, giving a usable 370-400 mm range without swapping the cylinder. This plain SKU lacks a magnet and cannot take a CMSE/DMSE sensor, and the air cushion only decelerates the load—it will not hold position without live air.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 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 JSIJ63X400-30 Is Used
Press Stroke Tuning
Dial in the exact 370-400 mm extend reach on a light assembly press without machining new hard stops.
Transfer Diverter
Adjust the extend endpoint on-site to sort different carton widths on a packaging line.
Vertical Lift Stop
Lift a 79 kg payload vertically and fine-tune the upper stop position to match varying pallet heights.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-30 the Right Cylinder?
The 30 mm adjustable window is ideal for sharing one spare across stroke variants or fine-tuning the end position during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 400 mm stroke is long, always use an external guide to prevent rod bending under side loads. You must add the -S option if you need CMSE/DMSE sensors, as this base version has no magnet.
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 JSIJ63X400-30 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 is 318 kgf at 1.0 MPa. It uses a G3/8 port, a 20 mm rod, M18x1.5 rod thread, and 29 mm adjustable cushions at both ends.
The nominal 400 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 30 mm on-site, yielding a usable range of 370-400 mm. The retract end is fixed. This stop sets the end position and is not a load lock, so you need a pilot-operated check valve or external rod lock to hold a load.
