Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-20
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X500-20 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 JSIJ63X500-20
The external adjuster lets you shorten the extend stroke on site by up to 20 mm, giving a usable range of 480-500 mm without changing the cylinder itself. Because the nominal 500 mm stroke is the maximum, you can fine-tune the stop exactly where the process demands. The hard-anodized aluminium profile barrel makes the body shorter and more compact than an ISO 15552 cylinder of the same bore.
This double-acting double-rod unit uses a G3/8 port and an M18x1.5 rod thread, with 29 mm adjustable air cushions at both ends to decelerate the payload smoothly. Note that this specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor; you would need the -S variant for position detection. Also, the cushion only decelerates the piston near the stroke end, it does not hold the load on air loss. For vertical or suspended loads, fit an external rod lock or a pilot-operated check valve to prevent drift.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |

| 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 JSIJ63X500-20 Is Used
Transfer Line Diverter
Dial in the 480-500 mm extend stop to push parts accurately onto a side lane without over-traveling into the main belt.
Pallet Stopper Gate
Use the external adjuster to fine-tune the end position so the stop gate catches pallets perfectly regardless of minor machine frame variations.
Press Feed Pusher
Shorten the extend stroke by up to 20 mm on site to set the exact material insertion depth into the press without swapping the actuator.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-20 the Right Cylinder?
The JSIJ adjustable-stroke mechanism is ideal when you want a shared spare across stroke variants or need to dial in an exact end position on the machine. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a 500 mm stroke, you must support the load with an external guide to prevent rod bending and side-load damage. Remember that without the -S suffix, this cylinder cannot accept magnetic sensors.
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 JSIJ63X500-20 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port.
The nominal 500 mm stroke is the maximum length. The external adjuster lets you shorten the extend stroke on site by up to 20 mm, yielding a usable range of 480-500 mm. The retract end remains fixed, and the adjuster sets the end position rather than acting as a load lock.
