Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-40
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X700-40 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 JSIJ100X700-40
The extruded hard-anodized aluminium barrel omits external rods, making the overall body shorter and more compact than a same-bore ISO 15552 unit. Air connections use a G1/2 port, and the M26x1.5 rod end threads into your mechanics.
The external stop screw provides a 40 mm on-site adjustment window, letting you fine-tune the extend end position between 660 mm and the 700 mm maximum without swapping the cylinder. The retract end remains fixed. Because this SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors for position detection. Note that the adjustable air cushions only decelerate the piston near the stroke ends; they do not hold the load. To prevent drift on air loss, fit an external rod lock or pilot-operated check valve.

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 JSIJ100X700-40 Is Used
Heavy Conveyor Diverting
Tunes the 700 mm extend stroke on-site by up to 40 mm to align heavy package diverters without machining new hard stops.
Large Assembly Press
Uses the compact JIS profile to save floor space while delivering enough thrust to seat large components over a 660 to 700 mm travel.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-40 the Right Cylinder?
The 40 mm adjustable stroke window is highly useful for matching end positions across multiple stations or dialing in a precise stop on-site. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Since the 700 mm stroke is quite long, always support the load with external guides to prevent rod bending and excessive side loading. Remember that without the -S suffix, this cylinder cannot host magnetic sensors.
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 JSIJ100X700-40 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 features a 100 mm bore, a 32 mm rod, a G1/2 port, and 33 mm adjustable cushions at both ends.
The nominal stroke is 700 mm, which is the maximum extend travel. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 660 to 700 mm. The retract end is fixed, and this mechanism sets the end position rather than locking the load.
