Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-40S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X450-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 450mm 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 JSIJ63X450-40S
The external stop screw provides a 40 mm adjustment window, meaning your usable extend travel spans 410 to 450 mm while the retract end remains fixed. You can fine-tune the end position without physically swapping the cylinder. The extruded hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit.
This -S variant includes a built-in piston magnet for CMSE/DMSE switches that drop directly into the side grooves. Pneumatic connections use a G3/8 port, and adjustable air cushions 29 mm long decelerate the payload at both ends. Remember that the cushion only slows the piston near stroke end; 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 |

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 JSIJ63X450-40S Is Used
Press Stroke Tuning
Dial in the exact 410 to 450 mm extend position on a pressing station without machining new hard stops, using the 40 mm external adjuster to compensate for material thickness variations.
Divertor Arm Positioning
Fine-tune the extend reach of a sorting divertor arm on-site, ensuring packages of different sizes are pushed accurately without changing the entire actuator.
Vertical Lift Stops
Adjust the extend stroke window on a lifting station to set precise upper travel limits, accommodating various pallet heights while relying on external guides for the 450 mm travel.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X450-40S the Right Cylinder?
The 40 mm adjustable window is highly useful when you want to standardize a shared spare across multiple stroke variants or dial in a precise end position on the machine. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a 450 mm stroke, you must support the load with an external guide to prevent rod bending and excessive side loading. The included magnet supports CMSE/DMSE sensors for position feedback.
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 JSIJ63X450-40S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa.
The nominal 450 mm extend stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 410 to 450 mm. The retract end is fixed, and this stop mechanism is for positioning only, not for holding a load.
