Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-75
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X800-75 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 JSIJ100X800-75
The extruded hard-anodized aluminium barrel omits tie rods entirely, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit. Air connections use a G1/2 port.
The -75 code defines an external adjuster window that lets you shorten the extend stroke on-site by up to 75 mm, giving a usable range of 725 to 800 mm while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder. This SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors. Note that the adjustable air cushions only decelerate the piston near stroke end; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a load.

Theoretical Output Force (Ø100mm)
| 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 JSIJ100~125 Adjustable Cylinder JSIJ100X800-75 Is Used
Heavy Pallet Lifts
Raises loaded pallets in distribution hubs, using the 75 mm extend window to dial in exact upper stop positions without re-mounting hardware.
High-Bay Storage Pushers
Actuates goods into deep-lane racking, where the 725 to 800 mm extend range accommodates varying package depths on the fly.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X800-75 the Right Cylinder?
The JSIJ series supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. The adjustable stroke is ideal for sharing a single spare across multiple stroke variants or dialling in exact end positions on-site. Because this is an 800 mm stroke, you must support the load with external guides to prevent rod bending and side-load damage. This non-magnet version cannot host position sensors; choose an -S variant if you need CMSE or DMSE switches.
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 JSIJ100X800-75 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. This 100 mm bore unit uses a G1/2 port.
The nominal stroke is 800 mm, which is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 75 mm, yielding a usable range of 725 to 800 mm. The retract end remains fixed, and the adjuster sets the end position rather than locking the load.
