Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-10S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X350-10S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 350mm 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 JSIJ63X350-10S
The external stop screw lets you shorten the extend stroke by up to 10 mm on site, giving a usable range of 340-350 mm without swapping the actuator. Its extruded hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 cylinder. The G3/8 port feeds the 20 mm rod, and the -S suffix means a built-in magnet is ready for CMSE or DMSE switches.
Air cushions at both ends provide 29 mm of deceleration, but note that a plain cylinder drifts on air loss—the cushion only slows the piston near the end of travel, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load. Operating pressure spans 0.15-1.0 MPa across a -20 to +70 C range. Because the 350 mm stroke is relatively long, use external guides to prevent rod bending and manage side 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 JSIJ63X350-10S Is Used
Press Stroke Tuning
Fine-tune the final 10 mm of a clamping or pressing operation on-site to accommodate material thickness variations without remounting the actuator.
Divertor Adjustment
Dial in the exact extend position for a sorting divertor arm on a packaging line, ensuring product transitions smoothly between belts.
Pallet Stop Calibration
Adjust the stopping point for varying pallet sizes on a conveyor, using the 10 mm window to set the precise 340-350 mm extend limit.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-10S the Right Cylinder?
The adjustable -10 mm window is ideal when you need to fine-tune a final end position across multiple stations or share a spare across stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet supports CMSE/DMSE sensors in the side grooves. For this 350 mm stroke, always mount external guides to absorb side loads and protect the rod from 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 JSIJ63X350-10S FAQ
This 63 mm bore cylinder has a G3/8 port and a 20 mm rod.
An external stop screw lets you shorten the extend stroke by up to 10 mm on site. The nominal 350 mm stroke is the maximum, giving a usable extend range of 340-350 mm, while the retract end remains fixed. This adjusts the end position but does not lock the load.
