Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X25-30S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X25-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 25mm 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 JSIJ63X25-30S
The hard-anodized aluminum barrel keeps the build clean without external rods.
The -30 code means an external adjuster can shorten the 25 mm extend stroke on-site by up to 30 mm, letting you fine-tune the end position without swapping the cylinder. Air connects via a G3/8 port. Because this is an -S SKU, a built-in magnet lets you fit CMSE or DMSE sensors directly into the side grooves for position detection.

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 JSIJ63X25-30S Is Used
Short-Stroke Clamping
Dials in the exact clamping contact point on-site using the 30 mm adjuster window, ensuring delicate parts are held firmly without crushing.
Transfer Diverter
Tunes the extend reach precisely to deflect packages of varying widths on a conveyor line without requiring multiple cylinder sizes.
Bin Gate Control
Regulates the material flow opening by trimming the extend stroke on-site, matching the exact dispense volume needed for different batch sizes.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X25-30S the Right Cylinder?
The adjustable stroke is ideal for sharing one spare across slight stroke variants or dialing in a precise end stop during commissioning. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. For any stroke over 300 mm, always guide the load to prevent side-load wear on 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 JSIJ63X25-30S FAQ
At 0.5 MPa it 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. It uses a G3/8 port and a 20 mm rod with an M18x1.5 thread.
The 25 mm nominal stroke is the maximum extend length. The external stop screw lets you shorten the extend stroke on-site by up to 30 mm, meaning you can set the usable extend travel anywhere down to zero. The retract end remains fixed. This stop only sets the end position; it does not lock the load.
