Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-75
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X450-75 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 JSIJ63X450-75
The hard-anodized aluminum barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit.
The -75 code means an external adjuster can shorten the 450 mm extend stroke by up to 75 mm on site, yielding a usable 375-450 mm range while the retract end stays fixed. This fine-tunes the end position without swapping the cylinder. Air connects via a G3/8 port, and adjustable cushions at both ends absorb shock. Note that this SKU lacks a magnet and cannot take a CMSE/DMSE sensor; for the 450 mm stroke, use external guides to prevent rod bending under side loads.

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 JSIJ63X450-75 Is Used
Transfer Push-Off Tuning
Dial in the exact push-off distance on a conveyor diverter within the 375-450 mm window without machining a new stop.
Pallet Positioning Arm
Fine-tune the extend end position to adapt to different pallet widths on the fly while benefiting from the compact JIS profile.
Press Load Alignment
Adjust the 75 mm extend window to set precise downward contact pressure before the fixed retract returns the tool.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-75 the Right Cylinder?
The adjustable stroke is ideal when you need to dial in the exact extend end-position on the machine or want a single spare part covering several stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a no-magnet SKU, it cannot accept position sensors; add the -S variant for CMSE/DMSE switches. Finally, at 450 mm of stroke, always support the load with external guides 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 JSIJ63X450-75 FAQ
It pushes 1559 N and pulls 1402 N at 0.5 MPa, and pushes 2182 N while pulling 1962 N at 0.7 MPa. The theoretical maximum force is 318 kgf at 1.0 MPa. The air port size is G3/8.
The external adjuster lets you shorten the extend stroke by up to 75 mm on site, giving a usable extend range of 375-450 mm from the 450 mm nominal maximum. The retract end remains fixed. This mechanism sets the end position but does not lock the load; use an external rod lock or pilot-operated check valve if you need to hold a load against air loss.
