Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-20S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X225-20S 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 JSIJ63X225-20S
The hard-anodized aluminum barrel keeps the assembly light, and the G3/8 porting feeds a 30-800 mm/s speed range. Because the -S suffix adds a piston magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position sensing.
The -20 code defines an external stop screw that lets you shorten the extend stroke on-site by up to 20 mm, yielding a usable 205-225 mm window while the retract end stays fixed. This on-site tuning means you can fine-tune the end position without physically swapping the cylinder, and it lets you standardize one spare across multiple stroke variants.

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 JSIJ63X225-20S Is Used
Stroke Tuning for Tooling
Dial in the exact 205-225 mm extend reach on-site to align clamping jaws without machining custom spacers or changing the actuator.
Package Divert Stop
Adjust the stop finger position in seconds to accommodate varying box sizes on a single line, using the G3/8 port for rapid cycling.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-20S the Right Cylinder?
The adjustable stroke is ideal for machines that need on-site end-position tuning or when you want a single spare part covering several stroke lengths. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. The included -S magnet supports CMSE/DMSE sensors. 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 JSIJ63X225-20S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa.
The -20 indicates an external adjuster that shortens the extend stroke by up to 20 mm on-site, giving a usable range of 205-225 mm from the 225 mm nominal maximum. The retract end remains fixed. Note that this mechanism only sets the end position; it does not hold the load on air loss, so you need an external rod lock or pilot-operated check valve for holding.
