Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-30S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X225-30S 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 JSIJ63X225-30S
The hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit. You can fine-tune the end position without swapping the cylinder, as the nominal 225 mm stroke serves as the maximum while the retract end remains fixed.
The integrated -S magnet allows CMSE or DMSE switches to drop directly into the side grooves for precise position sensing. Note that the adjustable air cushions only decelerate the piston near stroke end; an external rod lock or pilot-operated check valve is required to hold a load securely on air loss.

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 JSIJ63X225-30S Is Used
End-Position Trimming
Perfect for automated clamping stations where the exact extend reach needs a 30 mm on-site trim to accommodate different material thicknesses without changing the cylinder.
Transfer Diverter
Ideal for diverting packages on a conveyor line, using the adjustable stop to fine-tune the pusher distance and ensure items align perfectly with the downstream lane.
Vertical Lift Stop
Suited for compact vertical lifts where the hard-anodized barrel saves axial space and the external adjuster sets the precise raise height for various tote sizes.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-30S the Right Cylinder?
The -30 mm adjustable window is ideal for machines where the exact extend end-position needs on-site tuning or when a single spare cylinder must cover several stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 225 mm stroke is moderately long, always guide the load to prevent excessive side-loading on the rod.
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 JSIJ63X225-30S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port and a 20 mm rod with an M18x1.5 thread.
The external stop screw lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 195 to 225 mm. The nominal 225 mm stroke is the maximum, and the retract end is fixed. The stop sets the end position but does not lock the load.
