Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-30
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X225-30 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 JSIJ63X225-30
An external stop screw lets you shorten the extend stroke by up to 30 mm, giving a usable range of 195-225 mm without swapping the actuator. The hard-anodized aluminum extruded body keeps the unit more compact than a same-bore ISO 15552 cylinder, and the G3/8 port matches the bore standard.
The retract end remains fixed while you fine-tune the extend position. Note that this SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors; you would need the -S variant for position detection. Furthermore, the adjustable air cushions only decelerate the piston near stroke ends and do not hold the load on air loss.

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 JSIJ63X225-30 Is Used
End-Stop Calibration
Fine-tune the extend position by up to 30 mm on-site to dial in exact clamping depth without machining new hard stops.
Transfer Diverter
Adjust the extend stroke window to accommodate different product widths on a packaging line without changing the actuator.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-30 the Right Cylinder?
The 30 mm adjustable window is ideal when you need to share a spare cylinder across slightly different stroke variants or fine-tune a final end position on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnet SKU, it cannot support magnetic sensing. For any stroke length, always guide the load to prevent side-load damage to the rod seals.
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 JSIJ63X225-30 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port and a 20 mm rod.
The external adjuster allows you to shorten the extend stroke by up to 30 mm on-site. The nominal 225 mm stroke is the maximum, giving a usable extend range of 195-225 mm. The retract end is fixed, and the stop mechanism does not lock the load.
