Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-30
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X700-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 700mm 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 JSIJ100X700-30
Its extruded hard-anodized aluminum body is notably shorter and more compact than a same-bore ISO 15552 unit. The G1/2 port feeds the 32 mm rod, and the adjustable air cushions provide 33 mm of end-of-stroke deceleration.
The -30 code means an external adjuster can shorten the extend stroke on-site by up to 30 mm, giving a usable range of 670 to 700 mm while the retract end stays fixed. This lets you fine-tune the end position without swapping the cylinder. Note this SKU lacks a magnet and cannot take CMSE or DMSE sensors.

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 JSIJ100X700-30 Is Used
Press Stroke Calibration
Dial in the exact 670 to 700 mm extend reach on a heavy press without machining new spacers, using the external stop to set the final contact position.
Heavy Pallet Diverting
Push large loaded pallets at 0.5 MPa, relying on the 33 mm adjustable cushions to absorb the kinetic energy of the 100 mm bore at the end of travel.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-30 the Right Cylinder?
The JSIJ series supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. The on-site adjustability is ideal for sharing a spare across stroke variants or dialing in final end positions. Because this is a 700 mm stroke, you must use external guides to prevent rod bending and manage side loads. Without a -S suffix, this specific SKU cannot accept magnetic 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 JSIJ100X700-30 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 with an M26x1.5 thread.
The nominal 700 mm stroke is the maximum. An external adjuster lets you shorten the extend stroke by up to 30 mm on-site, giving a usable range of 670 to 700 mm. The retract end is fixed. This mechanism only sets the end position; it does not lock the load, so you need an external rod lock or pilot-operated check valve to hold a load on air loss.
