Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-30
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X500-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 500mm 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 JSIJ63X500-30
Its hard-anodized aluminum extruded barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder. The G3/8 port feeds the 30-800 mm/s speed range, while adjustable air cushions of 29 mm at each end absorb impact.
The -30 code means an external adjuster can shorten the extend stroke by up to 30 mm on site, giving a usable extend range of 470-500 mm (the 500 mm nominal stroke is the maximum, and the retract end remains fixed). Note this SKU lacks a magnet and cannot take a CMSE/DMSE sensor; for the sensing version you need the -S variant.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|

| 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 JSIJ63X500-30 Is Used
Transfer Line Divert
Fine-tunes the 470-500 mm extend position on-site to match varying pallet sizes without remounting the actuator.
Press Discharge Chute
Uses the 29 mm adjustable cushions to decelerate ejected parts smoothly over the long 500 mm travel.
Packaging Pusher
Adjusts the extend stop by up to 30 mm to accommodate different carton depths on a shared assembly line.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-30 the Right Cylinder?
The adjustable-stroke window is ideal when you want a shared spare across slightly different stroke variants or need fine end-position tuning without swapping the cylinder. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 500 mm stroke is long, always use an external guide to prevent rod bending and side-load damage. A plain cylinder drifts on air loss—the cushion only decelerates—so add an external rod lock or pilot-operated check valve if you need to hold a load.
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 JSIJ63X500-30 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.
The external adjuster lets you shorten the extend stroke by up to 30 mm on site. The usable extend range is 470-500 mm, with 500 mm being the maximum nominal stroke. The retract end is fixed, and the stop sets end position rather than locking the load.
