Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-30
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X175-30 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 JSIJ63X175-30
The external stop screw lets you shorten the forward travel by up to 30 mm, giving a usable range of 145 to 175 mm without changing the unit. The hard-anodized aluminium barrel uses no tie rods, making the body noticeably shorter and more compact than a same-bore ISO 15552 cylinder.
Air connects via a G3/8 port, driving the 20 mm rod at speeds of 30-800 mm/s with 29 mm adjustable air cushions at both ends. Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE sensors for position detection. 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 suspended weight securely.

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 JSIJ63X175-30 Is Used
Clamp Stroke Tuning
Dial in the exact 145 to 175 mm forward clamping position on-site to accommodate different part heights without swapping cylinders.
Transfer Diverter
Adjust the extend stop to set the precise pusher distance for routing varied box sizes onto secondary conveyor lines.
Pallet Stopper Gate
Fine-tune the retract stopper gate height by 30 mm to handle slight pallet dimension variations on the packaging line.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-30 the Right Cylinder?
The 30 mm adjuster window is ideal for sharing a single spare cylinder across multiple stroke variants or fine-tuning the end position during machine commissioning. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. For any stroke length at or above 300 mm, always guide the load to prevent excessive side-load wear on the rod seals.
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 JSIJ63X175-30 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 force is 318 kgf at 1.0 MPa. This 63 mm bore model uses a G3/8 air port and a 20 mm piston rod.
The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, providing a usable forward travel of 145 to 175 mm. The nominal 175 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position and does not lock the load.
