Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-50S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X100-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 100mm 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 JSIJ63X100-50S
The hard-anodized aluminum profile barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 cylinder.
The -50 code means an external adjuster can shorten the extend stroke by up to 50 mm on site, giving a usable range of 50 to 100 mm without changing the cylinder itself. Because this is an -S SKU, a built-in piston magnet lets you drop CMSE or DMSE reed and electronic switches directly into the side grooves. Pneumatic connections use a G3/8 port, and adjustable air cushions at both ends absorb end-of-stroke impact.

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 JSIJ63X100-50S Is Used
Press Fit Tuning
Dial in the exact 50 to 100 mm extend position on-site to seat delicate bearings without bottoming out the stroke.
Variable Length Diverter
Adjust the extend stop to deflect different package sizes on a single line, saving the cost of multiple cylinders.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-50S the Right Cylinder?
This model sits perfectly in the middle for medium-duty tasks. The adjustable stroke is ideal when you need to fine-tune an end position across multiple machine variants or share one spare across similar stroke lengths. Mounting options include FA, LB, TC, TCM1, and TCM2. The integrated magnet supports CMSE/DMSE sensors. For any stroke at or over 300 mm, always use external guide rails 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 JSIJ63X100-50S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. The air port is G3/8.
The nominal 100 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 50 mm on-site, yielding a usable range of 50 to 100 mm. The retract end is fixed. This stop sets the end position but does not lock the load.
