Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-30S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X400-30S 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 JSIJ63X400-30S
The external stop screw lets you trim the extend stroke by up to 30 mm, giving a usable 370 to 400 mm range while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder, and the hard-anodized aluminum barrel keeps the overall body more compact than a same-bore ISO 15552 unit.
The built-in -S piston magnet accepts CMSE or DMSE reed and electronic switches that drop directly into the side grooves. Air flows through a G3/8 port, and adjustable 29 mm cushions decelerate the load at both ends. Remember that a plain cylinder drifts on air loss; the cushion only slows the piston near the end, 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 |
|---|---|---|

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 JSIJ63X400-30S Is Used
Transfer Push-Off Tuning
Trim the 400 mm extend stroke by up to 30 mm on-site to perfectly match a changing conveyor push-off distance without remounting the actuator.
Press Positioning
Set a precise lower end position for a light assembly press, using the external adjuster to dial in the exact 370 to 400 mm depth required for the workpiece.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X400-30S the Right Cylinder?
The -30 mm adjuster is ideal when you need to tune the extend endpoint on-site or want a single shared spare across slightly different 400 mm stroke machines. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 400 mm, always support the load with an external guide rail to prevent rod bending and premature seal wear. The -S magnet version is required if you plan to use CMSE or DMSE position sensors.
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 JSIJ63X400-30S FAQ
At 0.7 MPa the push is 2182 N and the pull is 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port and a 20 mm rod.
The nominal stroke is 400 mm, which is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 370 to 400 mm. The retract end is fixed, and this stop only sets the end position; it does not lock the load.
