Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-20
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X175-20 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 JSIJ63X175-20
Its extruded hard-anodized aluminum barrel omits tie rods entirely, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port handles the air flow, while the M18x1.5 rod thread and 29 mm adjustable cushions at each end manage impact.
The -20 code defines a 20 mm external adjuster window, letting you shorten the extend stroke on site from the 175 mm maximum down to 155 mm without swapping the cylinder. This on-site tuning is ideal for dialing in exact end positions. Note that this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 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 JSIJ63X175-20 Is Used
End-Position Trimming
Dial in the exact extend stop on a machining fixture by shortening the stroke up to 20 mm on-site without disassembling the line.
Compact Diverting
Fit a short JIS-profile diverter into a tight pallet handling cell where a longer ISO 15552 cylinder would violate the machine envelope.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-20 the Right Cylinder?
The adjustable stroke is highly useful when you need to fine-tune a 155 to 175 mm end position on-site or want a shared spare across slight stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 175 mm stroke is under 300 mm, side-load risks are minimal, but always guide the load for longer strokes. Since this is a non-S SKU, it cannot accept magnetic 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 JSIJ63X175-20 FAQ
The theoretical max force is 318 kgf at 1.0 MPa. The air port is G3/8.
The 175 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 20 mm, yielding a usable extend range of 155 to 175 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve to hold a load against air loss.
