Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-40
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X400-40 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 JSIJ63X400-40
The hard-anodized aluminium barrel leaves out external rods, making the body shorter and more compact than a same-bore ISO 15552 unit.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 360 to 400 mm while the retract end stays fixed. This means you can fine-tune the stroke without swapping the cylinder. Air enters via a G3/8 port, driving a 20 mm rod at 30-800 mm/s. Note this SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

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 JSIJ63X400-40 Is Used
Conveyor Transfer Stop
Trim the extend stop by up to 40 mm on-site to perfectly align a pallet halt without changing the cylinder mount.
Clamp Position Tuning
Fine-tune the clamping depth on machined parts across a 360 to 400 mm window to compensate for material thickness.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-40 the Right Cylinder?
The 40 mm adjustable window is ideal when you need to trim the extend end by a few millimeters after installation or want a shared spare across slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 400 mm, you should use external guides to prevent rod bending under side loads. Without a magnet, this version 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 JSIJ63~80 Adjustable Cylinder JSIJ63X400-40 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 max is 318 kgf at 1.0 MPa. It uses a G3/8 port.
The nominal 400 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 40 mm on-site, giving a usable range of 360 to 400 mm. The retract end is fixed. This stop sets the end position and is not a load lock.
