Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X50-40
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X50-40 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 50mm 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 JSIJ100X50-40
Its extruded hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit. The G1/2 port feeds the 32 mm piston rod to generate substantial thrust.
An external adjuster lets you shorten the extend stroke on-site by up to 40 mm, dropping the usable forward travel from the 50 mm maximum down to 10 mm without swapping the cylinder. Note that this plain 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 |

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 JSIJ100X50-40 Is Used
Press Fit Tuning
Shorten the extend stroke on-site by up to 40 mm to set the exact bottoming position for a heavy press fit without changing the cylinder body.
Heavy Vertical Dwell
Use the 50 mm maximum stroke to lower a 200 kg assembly onto a fixture, adjusting the final resting height precisely at the machine.
Transfer Stopper Gate
Act as a heavy-duty stop gate on a conveyor, tweaking the extend length from 10 to 50 mm to accommodate different product sizes on the line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X50-40 the Right Cylinder?
The 40 mm adjuster window is ideal for sharing a single spare across multiple stroke variants, letting maintenance fine-tune the end position during installation. JSIJ mounting choices cover Basic, FA, LB, TC, TCM1 and TCM2. Because this specific SKU has no -S suffix, it cannot accept a magnetic switch. For any stroke length at or above 300 mm, always guide the load 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 JSIJ100X50-40 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa.
The 50 mm nominal stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke by up to 40 mm on-site, giving a usable range of 10 to 50 mm. The retract end remains fixed.
