Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-75S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X400-75S 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 JSIJ63X400-75S
The external stop screw provides a 75 mm adjustment window, letting you fine-tune the usable extend stroke anywhere from 325 mm up to the 400 mm maximum without swapping the actuator. Because the retract end remains fixed, only the forward end position shifts. The hard-anodized aluminum extruded barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. A built-in magnet (-S) enables direct mounting of CMSE or DMSE sensors in the side grooves.
Pneumatically, the G3/8 port feeds the 20 mm piston rod, and adjustable 29 mm air cushions at both ends absorb end-of-stroke impact. Remember that the cushion only decelerates the load; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

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 JSIJ63X400-75S Is Used
Transfer Push-Off
Dialing in the 75 mm extend window lets you fine-tune the exact push-off distance for varying product lengths on a conveyor without changing the cylinder.
Pallet Stopper Gate
Adjust the forward stop position on-site to act as a precise pallet stop gate, accommodating different pallet depths while using the full 400 mm stroke.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-75S the Right Cylinder?
The 63 mm bore sits perfectly in the middle for medium-duty tasks. The 75 mm adjustable window is highly useful when you need to synchronize end positions across multiple stations or dial in a precise reach on-site. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix means the piston magnet is already included for CMSE/DMSE switches. Because the 400 mm stroke creates leverage, always support the rod against side loads with an external guide to prevent 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 JSIJ63X400-75S FAQ
This 63 mm bore cylinder uses a G3/8 air port.
The external adjuster lets you shorten the extend stroke on-site by up to 75 mm. The usable extend range is 325 mm to the 400 mm maximum, while the retract end remains fixed. This mechanism sets the end position and does not lock the load.
