Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X1000-20S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X1000-20S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 1000mm 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 JSIJ63X1000-20S
The extruded hard-anodized aluminum barrel omits tie rods entirely, making the unit shorter and more compact than a same-bore ISO 15552 cylinder. An external adjuster allows you to shorten the extend stroke by up to 20 mm, yielding a usable range of 980-1000 mm without swapping the actuator.
The -S suffix means a built-in piston magnet is included for CMSE/DMSE switches that mount directly into the side grooves. 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 load securely against air loss.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 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 JSIJ63X1000-20S Is Used
Long-Transfer Pusher
Pushes parts down a 980 mm transfer line, using the 20 mm adjuster to fine-tune the exact reject position without moving the cylinder mounts.
High-Bay Divert Gate
Actuates a routing gate on a storage system, where the compact JIS profile saves axial space and the external stop dials in the gate angle perfectly.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X1000-20S the Right Cylinder?
The -20 mm adjustable window is highly useful when you need to fine-tune a shared spare across slightly different stroke variants or dial in a precise end position on the machine. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 1000 mm stroke is quite long, you must support the load with external guides to prevent rod bending and excessive side loading. The included -S magnet enables CMSE/DMSE sensor integration 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 JSIJ63X1000-20S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a 20 mm rod, G3/8 ports, M18x1.5 rod threads, and 29 mm adjustable air cushions at both ends.
The 1000 mm stroke is the nominal maximum. The external adjuster lets you shorten the extend stroke on-site by up to 20 mm, giving a usable extend range of 980-1000 mm. The retract end remains fixed. This mechanism sets the end position but does not function as a load lock.
