Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X275-100S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X275-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 275mm 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 JSIJ63X275-100S
The hard-anodized aluminum barrel has no exposed tie rods. A built-in magnet (-S) lets you fit CMSE or DMSE sensors into the side grooves.
The external adjuster allows you to shorten the extend stroke on-site by up to 100 mm, giving a usable range of 175 to 275 mm while the retract end stays fixed. Pneumatic connections use a G3/8 port.

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

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 JSIJ63X275-100S Is Used
Forming Press Stop
Dial in the exact material contact point on-site using the 100 mm adjuster window without remounting the entire actuator.
Variable Transfer Diverter
Shift the extend endpoint between 175 mm and 275 mm on the line to route different package sizes through the same lane.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X275-100S the Right Cylinder?
The adjustable stroke is ideal for sharing one spare across stroke variants or fine-tuning end positions without swapping the cylinder. Mounting options include FA, LB, TC, TCM1, and TCM2. The included -S magnet supports reed and electronic switches. Because the stroke is 275 mm, always use a guide rail to prevent side-load damage.
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 JSIJ63X275-100S FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa. At 0.7 MPa it pushes 2182 N and pulls 1962 N. The theoretical maximum is 318 kgf at 1.0 MPa.
An external stop screw lets you shorten the extend stroke by up to 100 mm on-site, giving a usable range of 175 to 275 mm. The nominal 275 mm stroke is the maximum, and the retract end is fixed. This stop only sets the end position; it does not lock the load.
