Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-40S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X175-40S 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 JSIJ63X175-40S
A built-in magnet (-S) enables CMSE/DMSE sensor switching, while the hard-anodized aluminum barrel is more compact than a same-bore ISO 15552 unit.
The external stop screw provides a 40 mm shortening window, letting you tune the usable extend stroke anywhere from 135 to 175 mm without changing the hardware; the retract end remains fixed. The G3/8 port and M18x1.5 rod thread match the standard 63 mm architecture. Remember that the adjustable stop sets end position only—it is not a load lock, so add an external rod lock or pilot-operated check valve if you need to hold a load on air loss.

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 JSIJ63X175-40S Is Used
Press Fit Tuning
Dial in the exact 135 to 175 mm extend position for pressing bearings without machining custom spacers.
Variable Diverter Arm
Adjust the pusher reach on-site to handle different package sizes on a single sorting line.
Pallet Stop Mechanism
Fine-tune the stopping depth for various pallet widths using the 40 mm external stroke window.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-40S the Right Cylinder?
The 40 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or fine-tuning the end position during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S suffix means the piston magnet is present for CMSE/DMSE switches. For any stroke at or over 300 mm, always use a guide rail to prevent side-load damage to the rod seal.
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 JSIJ63X175-40S 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. It uses a G3/8 port and features a 29 mm adjustable air cushion at each end.
The nominal 175 mm extend stroke is the maximum. The external adjuster 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 stop screw only sets the end position and does not lock the load.
