Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-50
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X175-50 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 JSIJ63X175-50
The external stop screw provides a 50 mm adjustment window, letting you dial the usable extend stroke down from the 175 mm maximum to 125 mm without swapping the actuator. Built with a hard-anodized aluminum barrel, the body is noticeably shorter and more compact than a same-bore ISO 15552 unit.
Air connects via twin G3/8 ports, driving a 20 mm rod at speeds of 30-800 mm/s with 29 mm adjustable cushions at both ends. Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors. Remember that the adjustment screw sets the end position; it does not lock the load. If your application requires holding a load on air loss, you must fit an external rod lock or pilot-operated check valve, as the cushion only decelerates the piston.

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 JSIJ63X175-50 Is Used
Clamp Stroke Tuning
Dial in the exact 125 to 175 mm extend reach on-site to clamp varying part heights without machining custom spacers.
Transfer Diverter
Set the precise push-off distance for moving boxes between parallel conveyor lanes using the external stop screw.
Pallet Stop Gate
Adjust the gate extension length on the fly to accommodate different pallet depths while maintaining a fixed retract.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-50 the Right Cylinder?
When sizing this model, consider the 50 mm adjuster as a way to fine-tune end positions across multiple stations using one shared spare. The JSIJ series supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. For any stroke at or above 300 mm, always guide the load to prevent rod side-loading. Note that this non-magnetic version cannot host 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 JSIJ63X175-50 FAQ
At 0.5 MPa it pushes 1559 N and pulls 1402 N. At 0.7 MPa it pushes 2182 N and pulls 1962 N. The theoretical maximum is 318 kgf at 1.0 MPa. This 63 mm bore unit uses G3/8 air ports, a 20 mm rod, and M18x1.5 rod threads.
The 175 mm nominal stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 125 to 175 mm. The retract end remains fixed, and the adjuster only sets the end position without locking the load.
