Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-10S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X400-10S 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 JSIJ63X400-10S
An external stop screw lets you shorten the extend stroke by up to 10 mm, giving a usable range of 390 to 400 mm without swapping the actuator. The hard-anodized aluminum extruded barrel keeps the total envelope more compact than a same-bore ISO 15552 unit. It connects via a G3/8 port and includes a built-in magnet for position sensing.
The -S suffix means the side grooves are ready to accept CMSE or DMSE reed and electronic switches. Remember that the adjustable stop sets the end position but does not lock the load; you will need an external rod lock or pilot-operated check valve to hold a suspended weight securely.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|

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 JSIJ63X400-10S Is Used
Transfer Push-Off Tuning
Fine-tune the 390 to 400 mm extend position on-site to strike a product at the exact edge of a conveyor belt without re-mounting the cylinder.
Clamp Position Calibration
Use the magnetic piston with CMSE sensors to verify clamp engagement, tweaking the extend end-point by a few millimeters to suit varying part tolerances.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-10S the Right Cylinder?
When sizing this actuator, stepping down to a 50 mm bore drops the 0.5 MPa push force to 982 N, while stepping up to an 80 mm bore raises it to 2513 N. The 10 mm extend-shortening window is ideal for sharing a single spare across slightly different stroke variants or fine-tuning a fixture position on the machine. You can mount it using the basic body, FA, LB, TC, TCM1, or TCM2 brackets. Because the 400 mm stroke creates leverage, always use an external guide rail to prevent rod bending and side-load damage. The included magnet supports CMSE/DMSE sensors for precise positioning 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 JSIJ63X400-10S FAQ
At 0.7 MPa, push increases to 2182 N and pull to 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa.
The nominal 400 mm stroke is the maximum length. An external adjuster screw lets you shorten the extend stroke on-site by up to 10 mm, providing a usable extend range of 390 to 400 mm. The retract end remains fixed, and this mechanism only sets the end position rather than locking the load.
