Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-75S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X225-75S 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 JSIJ63X225-75S
The external stop screw lets you shorten the extend stroke by up to 75 mm, giving a usable range of 150 to 225 mm, while the retract end stays fixed. An extruded hard-anodized aluminium barrel keeps the body shorter and more compact than a same-bore ISO 15552 unit. The -S suffix means a built-in magnet is fitted, allowing CMSE or DMSE sensors to drop directly into the side grooves for position detection.
This double-acting double-rod actuator runs at 30-800 mm/s with adjustable 29 mm air cushions at both ends to soften impact. Remember that a plain cylinder does not hold load on air loss; the cushion only decelerates near the stroke end. For a held load, fit an external rod lock or pilot-operated check valve.

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 JSIJ63X225-75S Is Used
End-Position Trimming
Fine-tune the extend stop on clamping assemblies by up to 75 mm without mechanically remounting the entire actuator.
Variable Transfer Push
Adjust the push-off distance on the fly for mixed product sizes on a single line, using the full 225 mm stroke when needed.
Shared Spare Actuator
Stock one cylinder and dial the extend stroke down to 150 mm to cover multiple shorter-stroke machines during maintenance.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-75S the Right Cylinder?
The -75 mm adjustable window is ideal for sharing one spare across multiple stroke variants or fine-tuning the end position without swapping the cylinder. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The integrated -S magnet supports CMSE/DMSE switches. Because the 225 mm stroke exceeds 300 mm only marginally, always guide the load to prevent side-load wear on the rod seals.
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 JSIJ63X225-75S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 air port.
The nominal 225 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable extend range of 150 to 225 mm. The retract end is fixed, and the stop sets position rather than locking the load.
