Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-30S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X450-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 450mm 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 JSIJ63X450-30S
The hard-anodized aluminium barrel keeps the assembly lightweight while providing a 450 mm extend stroke that can be fine-tuned down by 30 mm on-site via an external stop screw. This means the usable extend range is 420-450 mm, letting you dial in the exact end position without swapping the cylinder. Air connects via a G3/8 port, and the -S suffix indicates a built-in piston magnet for CMSE/DMSE sensors.
The external adjuster sets the extend end position but does not lock the load; a plain cylinder drifts on air loss, so add an external rod lock or pilot-operated check valve if you need to hold a suspended weight. The adjustable air cushions provide 29 mm of deceleration at each end to absorb kinetic energy. Because the 450 mm stroke creates leverage, use an external guide rail to prevent rod bending and side loads. Operating pressure ranges from 0.15 to 1.0 MPa across a -20 to +70 C temperature band.

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 JSIJ63X450-30S Is Used
Divert Gate Tuning
Fine-tune the extend position by up to 30 mm on-site to perfectly align a pneumatic divert gate without changing the cylinder mount.
Variable Height Stops
Adjust the extend end point dynamically for different package sizes on a packing line, using the external stop screw to set the exact 420-450 mm reach.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-30S 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 30 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or fine-tuning the end position on-site without machining. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. The -S magnet allows CMSE/DMSE switches to drop directly into the side sensor grooves. For the 450 mm stroke, always support the load with an external linear guide to avoid rod bending and premature seal 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 JSIJ63X450-30S FAQ
At 0.5 MPa this 63 mm bore cylinder pushes 1559 N and pulls 1402 N. At 0.7 MPa it pushes 2182 N and pulls 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa.
The nominal 450 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 420-450 mm. The retract end remains fixed, and the adjuster only sets the end position without locking the load.
