Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X50-10TC
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X50-10TC is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 50mm 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 JSIJ63X50-10TC
The nominal 50 mm stroke remains the maximum travel, while the retract end stays fixed. Built with an extruded hard-anodized aluminum barrel, the body is notably shorter and more compact than an ISO 15552 cylinder of the same bore. Air connections use a G3/8 port.
This double-acting double-rod unit relies on a 29 mm adjustable air cushion at each end to decelerate the moving load smoothly. Because this SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors for position detection. Remember that the cushion only slows the piston near the end of travel; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a load securely.

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 JSIJ63X50-10TC Is Used
Clamp Stroke Tuning
Dial in the exact 40 to 50 mm extend reach on a machining fixture to accommodate different part thicknesses without changing the cylinder body.
Transfer Diverter Stop
Use the TC mount to pivot the stop gate and fine-tune the 10 mm extend window so packages halt precisely at the sensor checkpoint.
Sealing Head Press
Adjust the extend end position on site to apply exactly the right contact pressure for varying carton heights on a sealing line.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X50-10TC the Right Cylinder?
When sizing this 63 mm bore, stepping down to a 50 mm bore drops the 0.5 MPa push force to 982 N, while stepping up to an 80 mm bore raises it to 2513 N. The -10 mm adjustable window is ideal for fine-tuning the extend end position without swapping the cylinder, letting you standardize one spare across slight stroke variants. It ships with a TC clevis mounting interface, and FA, LB, TCM1, and TCM2 brackets are also available. For any stroke length of 300 mm or more, always guide the load to prevent side-load damage to 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 JSIJ63X50-10TC FAQ
At 0.7 MPa the push is 2182 N and the pull is 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa. The air port size is G3/8.
The nominal 50 mm stroke is the maximum travel. The external adjuster lets you shorten the extend stroke by up to 10 mm on site, giving a usable extend range of 40 to 50 mm. The retract end remains fixed, and the adjuster sets the end position rather than locking the load.
