Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-40
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X175-40 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 JSIJ63X175-40
Its extruded hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder. The G3/8 port and M18x1.5 rod thread ensure straightforward integration.
The external stop screw provides a 40 mm adjustable window, letting you shorten the extend stroke from the 175 mm maximum down to 135 mm right on the floor. This on-site end-position tuning means you can fine-tune the motion without swapping the cylinder. Note that this SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

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 JSIJ63X175-40 Is Used
Stroke Tuning for Clamping
Dial in the exact clamping contact point by shortening the extend stroke up to 40 mm on-site, accommodating varying part tolerances without machine teardown.
Adjustable Transfer Stop
Act as a height-specific stop on a packaging line, using the external adjuster to set the precise 135 to 175 mm extend position for different box sizes.
Shared Spare Inventory
Keep one cylinder as a universal spare for multiple 63 mm bore machines, adjusting the extend stroke on the floor to match the specific 175 mm or shorter requirement.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-40 the Right Cylinder?
The adjustable stroke is a major advantage when you need to share one spare across slight stroke variants or dial in a final end position on-site. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. Because this is a non-magnetized SKU, you cannot fit position sensors; choose the -S variant if you need CMSE or DMSE switches. For any stroke at or over 300 mm, always use a guide rail to prevent side-load wear.
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 JSIJ63X175-40 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port and a 20 mm rod.
The nominal 175 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 40 mm on-site, giving a usable range of 135 to 175 mm. The retract end is fixed. This mechanism only sets the end position; it does not lock the load, so you need an external rod lock or pilot-operated check valve to hold a load on air loss.
