Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-75S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X800-75S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 800mm stroke, G1/2 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 JSIJ100~125 Adjustable Cylinder JSIJ100X800-75S
The hard-anodized aluminium extrusion keeps the assembly light while housing a 32 mm rod and G1/2 ports. A built-in magnet (-S) lets you drop CMSE or DMSE reed and electronic switches directly into the side grooves for precise position sensing.
The -75 code means an external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable forward range of 725 to 800 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder, which is ideal for sharing a spare across stroke variants. Note that the adjustable stop sets position only; it is not a load lock, so use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |

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 JSIJ100~125 Adjustable Cylinder JSIJ100X800-75S Is Used
Pallet Positioning
Fine-tune the 725 to 800 mm extend reach on-site to push pallets into a wrapping station, accommodating varying load depths without changing the actuator.
Heavy Diverting
Divert large totes along a conveyor by adjusting the extend stroke to match lane widths perfectly, relying on the compact JIS profile to save floor space.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-75S the Right Cylinder?
This 100 mm bore sits near the top of the range, pushing 3927 N at 0.5 MPa; step down to an 80 mm bore for 2513 N if your load is lighter, or move up to 125 mm for 6136 N when you need maximum thrust. The -75 mm adjustable window is invaluable when you need on-site end-position tuning or want a single spare covering several stroke lengths. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The -S magnet supports CMSE/DMSE sensors. Because the 800 mm stroke is long, always use external guides to prevent rod bending and manage side loads.
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 JSIJ100~125 Adjustable Cylinder JSIJ100X800-75S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 32 mm rod.
The nominal 800 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable range of 725 to 800 mm. The retract end is fixed, and this stop only sets position; it does not lock the load.
