Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-50S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X225-50S 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 JSIJ63X225-50S
An external adjuster lets you shorten the extend stroke by up to 50 mm, giving a usable range of 175 to 225 mm while the retract end remains fixed. The extruded hard-anodized aluminum barrel keeps the body shorter and more compact than a same-bore ISO 15552 unit. Air connects via a G3/8 port, and the -S suffix means a built-in magnet is ready for CMSE or DMSE sensors.
This double-acting double-rod actuator runs at 30-800 mm/s with 29 mm adjustable air cushions at both ends to smooth out stops. The external stop screw sets the end position but does not lock the load; without live air the piston drifts, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended weight.

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 JSIJ63X225-50S Is Used
Sorter Diverter Tuning
Fine-tune the extend reach by up to 50 mm on-site to perfectly align a package diverter arm without machining new mount holes.
Clamp Position Adjustment
Adjust the extend stroke from 175 to 225 mm to accommodate different part heights in a machining fixture while maintaining 1559 N of clamping force.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X225-50S the Right Cylinder?
The -50 mm adjustable window is ideal when you need to fine-tune the extend end position on-site without swapping cylinders, or when you want a shared spare across slightly different stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet supports direct CMSE/DMSE sensors for position feedback. Because the 225 mm stroke approaches the 300 mm side-load threshold, guide the load along its travel to prevent rod bending.
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 JSIJ63X225-50S FAQ
This 63 mm bore cylinder uses a G3/8 port and a 20 mm rod with an M18x1.5 thread.
The nominal 225 mm stroke is the maximum. An external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 175 to 225 mm. The retract end is fixed, and this stop screw only sets the end position; it does not lock the load.
