Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-20
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X225-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 225mm 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 JSIJ63X225-20
Its extruded hard-anodized aluminium barrel omits tie rods entirely, making the overall body shorter and more space-efficient than a same-bore ISO 15552 unit.
The -20 code defines a 20 mm external adjuster window, letting you fine-tune the extend end position on-site across a 205 to 225 mm usable range without swapping the cylinder. Air connects via a G3/8 port, and the retract end remains fixed. 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 |
| 0.7 MPa | 1962 N | 1962 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 JSIJ63X225-20 Is Used
Stroke Tuning for Clamps
Dial in the exact 205 to 225 mm clamp reach on-site using the external adjuster to accommodate varying material thicknesses without machine teardown.
Package Divert Stroke
Fine-tune the diverter arm end position by up to 20 mm to perfectly match new carton sizes on a packaging line.
Shared Spare Inventory
Keep one cylinder as a universal spare for multiple 63 mm bore machines, adjusting the extend stroke locally to fit various 200 mm class applications.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-20 the Right Cylinder?
The 20 mm adjustable window is ideal for sharing one spare across several stroke variants or dialing in end positions on-site. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a 225 mm stroke, guide the load to prevent side-loading the rod. Note that this non-magnet version cannot host sensors; choose an -S variant for CMSE or DMSE switches.
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 JSIJ63X225-20 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It features a 63 mm bore, a 20 mm rod, a G3/8 port, and a 29 mm adjustable air cushion at each end.
The -20 indicates an external stop screw window that lets you shorten the extend stroke by up to 20 mm on-site. The usable extend range is 205 to 225 mm, with 225 mm being the maximum nominal stroke. The retract end is fixed. This mechanism sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve to hold a load securely.
