Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-10
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X300-10 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 300mm 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 JSIJ100X300-10
The extruded hard-anodized aluminium profile barrel keeps the total length shorter than a same-bore ISO 15552 unit, saving valuable machine space without losing thrust. A G1/2 port feeds the double-acting double-rod mechanism, while adjustable air cushions of 33 mm absorb impact at both ends.
The external stop screw lets you trim the extend stroke by up to 10 mm directly on the floor, giving a usable 290 to 300 mm range while the retract end stays fixed. This on-site tuning means you can dial in the exact end position without swapping the cylinder. Note this SKU lacks a magnet, so it cannot take CMSE or DMSE sensors; add the -S variant if you need position detection.

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 JSIJ100X300-10 Is Used
Divert Gate Tuning
Trim the 300 mm extend stroke by 10 mm on-site to perfectly align a heavy parcel divert gate without machining new mountings.
Pallet Stop Adjustment
Fine-tune the end position of a 200 kg pallet stopper on the fly, using the external adjuster to compensate for varying load sizes.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-10 the Right Cylinder?
The 10 mm adjustable window is ideal for sharing a spare across slightly different stroke variants or fine-tuning a final end position. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 300 mm, always support the load with an external guide to prevent rod bending and excessive side loading. Remember that a plain cylinder drifts on air loss—the cushion only decelerates, so fit an external rod lock or pilot-operated check valve for held 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 JSIJ100X300-10 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 is 801 kgf at 1.0 MPa. It uses a G1/2 port, a 32 mm rod, and 33 mm adjustable cushions at both ends.
The nominal 300 mm stroke is the maximum. The external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 290 to 300 mm. The retract end remains fixed, and this stop is for positioning only, not for holding a load.
