Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-50S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X400-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 400mm 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 JSIJ63X400-50S
The nominal 400 mm stroke remains the maximum travel, letting you fine-tune the end position without physically swapping the actuator. Because it uses an extruded hard-anodized aluminum barrel, the overall body is shorter and more compact than a same-bore ISO 15552 unit.
The built-in piston magnet supports CMSE/DMSE switches that mount directly into the side grooves, enabling precise position detection. Air connects via a G3/8 port, and while the adjustable air cushions decelerate the piston smoothly at both ends, note that a plain cylinder drifts on air loss—the cushion decelerates but does not lock, so fit an external rod lock for held loads.

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 JSIJ63X400-50S Is Used
Conveyor Diverter Timing
Dial in the 50 mm extend window to match varying package sizes on a sorting line without changing the entire actuator assembly.
Vertical Material Lift
Lifts approximately 79 kg of raw material safely, using the 400 mm stroke to reach upper tiers while relying on external guides for stability.
Machining Clamping Stop
Provides 1559 N of clamping force at 0.5 MPa, with the external stop screw allowing precise retraction of the jaw for part unloading.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-50S the Right Cylinder?
The 50 mm adjustable window is ideal for sharing a single spare cylinder across multiple stroke variants or dialing in exact end positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix equips the cylinder for CMSE/DMSE sensors. Because the 400 mm stroke is relatively long, always support the load with an external guide to prevent rod bending and excessive side loading.
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 JSIJ63X400-50S FAQ
The -50 indicates a 50 mm external adjuster window. The nominal 400 mm stroke is the maximum, and you can shorten the extend stroke down to 350 mm on-site. The retract end remains fixed, and the stop sets the end position rather than locking the load.
