Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-30S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X175-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 175mm 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 JSIJ63X175-30S
The hard-anodized aluminum profile barrel keeps the overall envelope more compact than a same-bore ISO 15552 unit, and the G3/8 port matches the airflow demands of this capacity class.
The -30 code means an external stop screw lets you trim the extend stroke from the 175 mm maximum down to 145 mm right at the machine, fine-tuning the end position without swapping the cylinder. Because this is an -S SKU, the built-in piston magnet works directly with CMSE or DMSE switches in the side grooves for precise position detection.

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

| 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 JSIJ63X175-30S Is Used
Stroke Tuning for Forming Presses
Dial in the exact 145 to 175 mm extend position on-site to accommodate different material thicknesses without changing the entire actuator setup.
Adjustable Package Diverters
Alter the extend reach on the fly to handle varying box sizes on a sorting line, using the -S magnet to confirm the retracted home position.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-30S the Right Cylinder?
The adjustable stroke is ideal for sharing a spare across stroke variants or dialing in end positions on-site. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. For any stroke at or over 300 mm, always guide the load to prevent side-load damage. Note that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve if you need to hold a load.
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 JSIJ63X175-30S FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa.
The nominal 175 mm stroke is the maximum length. The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 145 to 175 mm. The retract end remains fixed, and this stop only sets the end position rather than locking the load.
