Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-30
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X275-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 275mm 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 JSIJ100X275-30
The hard-anodized aluminium barrel keeps the assembly light, and the G1/2 port handles the air volume needed for rapid cycling.
The JSIJ100X275-30 uses an external stop screw to shorten the extend stroke on site by up to 30 mm, giving a usable forward travel of 245 to 275 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder, which is ideal for sharing a spare across stroke variants. Note that this specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor; order an -S variant if you need position detection. A plain cylinder also drifts on air loss, so fit an external rod lock or pilot-operated check valve if the load must be held.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 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 JSIJ100X275-30 Is Used
Press Fit Tuning
Dial in the exact 245 to 275 mm extend position for seating bearings without machining custom spacers.
Heavy Diverter Arm
Pushes large pallets on a packaging line, using the adjustable stop to compensate for varying product widths.
Shared Spare Stock
Keep one cylinder on the shelf and shorten the extend stroke on site to cover multiple 100 mm bore machine variants.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-30 the Right Cylinder?
The adjustable 30 mm window is invaluable for dialling in exact end positions on site or keeping one spare for several stroke lengths. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the 275 mm stroke exceeds 300 mm only marginally, guide the load to prevent side-loading the 32 mm rod, and remember this no-magnet version cannot accept 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 JSIJ100X275-30 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa the push is 5497 N and the pull is 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 air port, a 32 mm rod, and has 33 mm adjustable air cushions at both ends.
An external stop screw lets you shorten the extend stroke on site by up to 30 mm. The nominal 275 mm stroke is the maximum, so usable forward travel is 245 to 275 mm. The retract end is fixed. This stop only sets the end position; it does not lock the load.
