Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-50
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X500-50 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 JSIJ63X500-50
The hard-anodized aluminium barrel keeps the assembly light while housing a 29 mm adjustable air cushion at each end. It feeds air through a G3/8 port and drives a 20 mm rod with an M18x1.5 thread.
The -50 code defines an external stop-screw window that lets you trim the extend stroke from 500 mm down to 450 mm on-site, fixing the retract end. Note this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

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 JSIJ63X500-50 Is Used
Sorter Diverter Tuning
Dial in the exact 450 to 500 mm extend reach of a package diverter arm on-site to match varying lane widths without changing the cylinder.
Pallet Stop Adjustment
Fine-tune the stopping position of a pallet on a roller bed by shortening the extend stroke up to 50 mm to accommodate different pallet depths.
Press Down-Stroke Setup
Set the precise lower end position for a light-duty pressing or holding operation, tweaking the 500 mm nominal stroke to the exact needed depth.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X500-50 the Right Cylinder?
The adjustable stroke shines when you need to fine-tune an end position without swapping the cylinder or want a shared spare across stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a 500 mm stroke, always use an external guide to prevent rod bending under side loads. For position sensing, you must step up to an -S variant.
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 JSIJ63X500-50 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 max force is 318 kgf at 1.0 MPa. It uses a G3/8 port, a 20 mm rod, M18x1.5 rod thread, and 29 mm adjustable cushions.
The nominal 500 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 450 to 500 mm. The retract end remains fixed. This stop sets the end position but does not lock the load.
