Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-50
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X700-50 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 JSIJ100X700-50
The extruded hard-anodized aluminium barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. A G1/2 port feeds the 32 mm piston rod, while adjustable 33 mm air cushions decelerate the payload at each end.
The external stop screw lets you trim the extend stroke on-site by up to 50 mm, giving a usable 650-700 mm forward travel while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. Note that this SKU lacks a magnet and cannot take a CMSE or DMSE sensor; order a -S variant for position detection. The stop screw sets travel but is not a load lock, so fit an external rod lock or pilot-operated check valve if you need to hold a load against air loss.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 N |
| Max (@1.0 MPa) | 719 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 JSIJ100~125 Adjustable Cylinder JSIJ100X700-50 Is Used
Press Stroke Calibration
Dial in the exact 650 to 700 mm extend reach on a large forming press without machining new spacers, using the external adjuster to set the precise contact point.
Pallet Positioning Stop
Act as a heavy-duty 3927 N end-stop for oversized pallets on a conveyor, fine-tuning the 50 mm window to accommodate varying load lengths on the fly.
Heavy Vertical Lowering
Lower 200 kg fixtures smoothly in a vertical lift rig, relying on the 33 mm adjustable air cushions to decelerate the payload safely at the end of the 700 mm stroke.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-50 the Right Cylinder?
Size this 100 mm bore against the 80 mm and 125 mm neighbours. The 50 mm adjustable window is ideal for sharing one spare across several stroke variants or dialling in the exact end position on-site. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 700 mm stroke is long, always support the rod against side-load bending and use an external guide rail to prevent premature seal wear. As a non-magnet SKU, it cannot host a reed switch.
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 JSIJ100X700-50 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 extend stroke is the maximum. The external stop screw lets you shorten the forward travel by up to 50 mm on-site, yielding a usable extend range of 650-700 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load.
