Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X225-30
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X225-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 225mm 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 JSIJ100X225-30
Its hard-anodized extruded aluminum profile is noticeably shorter than an ISO 15552 cylinder of the same bore, saving valuable machine space without losing strength. The G1/2 port feeds the chamber efficiently, while the 33 mm adjustable air cushions at each end absorb impact energy.
The external stop screw lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 195 to 225 mm without changing the cylinder itself. Note that this specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

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 JSIJ100X225-30 Is Used
Press Fit Tuning
Fine-tune the 195 to 225 mm extend position on-site to seat bearings perfectly without swapping actuators.
Pallet Stop Adjustment
Shorten the extend stroke by up to 30 mm to accommodate varying pallet widths on a shared conveyor line.
Vertical Load Lowering
Lower heavy 200 kg fixtures safely, relying on the 33 mm cushions to decelerate the load at the end of travel.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X225-30 the Right Cylinder?
The adjustable stroke is ideal for sharing a single spare cylinder across multiple stroke variants or fine-tuning an end position on the factory floor. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. Because this is a non-magnetized SKU, you cannot add position sensors; upgrade to an -S variant for CMSE/DMSE switches. For any stroke at or above 300 mm, always use a guide rail to prevent side-load damage.
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 JSIJ100X225-30 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 33 mm adjustable air cushion at each end.
The nominal 225 mm stroke is the maximum length. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable extend range of 195 to 225 mm. The retract end remains fixed. This mechanism only sets the end position; it does not lock the load, so use a pilot-operated check valve for holding.
