Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-100S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X225-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 225mm 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 JSIJ63X225-100S
Because it is a JSIJ adjustable-stroke variant, an external stop screw lets you trim the extend stroke on site by up to 100 mm, dropping the usable extension from the 225 mm maximum down to 125 mm without swapping the cylinder. The retract end stays fixed, and the built-in magnet (-S) supports CMSE/DMSE sensors in the side grooves for position feedback.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|

| 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 JSIJ63X225-100S Is Used
End-Position Trimming
Dial in the exact extend stop on a clamping fixture by shortening the 225 mm stroke up to 100 mm on site without changing the cylinder.
Variable Transfer Push
Adjust the push-off distance on a transfer line to handle different carton sizes using the external stop screw.
Shared Spare Inventory
Keep one 63 mm bore cylinder as a universal spare, adjusting the extend stroke down to 125 mm to fit multiple machines.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-100S the Right Cylinder?
The adjustable window is ideal for sharing a single spare across several stroke variants or fine-tuning an end position on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The integrated magnet works with CMSE/DMSE switches. For this 225 mm stroke, ensure adequate side-load guidance to prevent rod bearing wear.
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 JSIJ63X225-100S 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. The air port is G3/8, the rod is 20 mm with an M18x1.5 thread, and it has 29 mm adjustable air cushions at both ends.
The nominal 225 mm extend stroke is the maximum. An external stop screw lets you shorten the extend stroke on site by up to 100 mm, giving a usable extension range of 125 to 225 mm. The retract end remains fixed. This stop only sets the end position; it does not lock the load.
