Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X150-20
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X150-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 150mm 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 JSIJ100X150-20
The extruded hard-anodized aluminium barrel leaves out external rods, making the body shorter and more compact than a same-bore ISO 15552 unit. A G1/2 port supplies the air, while a 32 mm rod and M26x1.5 thread handle the mechanical drive.
The -20 code means an external adjuster can shorten the extend stroke on-site by up to 20 mm, giving a usable forward travel of 130 to 150 mm without swapping the cylinder. This on-site tuning is ideal for dialling in a precise end position. Note that this plain SKU lacks a magnet and cannot take a CMSE/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 JSIJ100X150-20 Is Used
Press Tuning
Dial in the exact 130 to 150 mm extend contact point for a light assembly press without machining new spacers.
Clamp Adjustment
Shorten the forward stroke on-site by up to 20 mm to accommodate varying part heights in a machining fixture.
Vertical Set-Down
Lift and lower a 200 kg payload vertically, using the adjustable stop to soften the final placement distance.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X150-20 the Right Cylinder?
When sizing this 100 mm bore, stepping down to an 80 mm cylinder drops the 0.5 MPa push force to 2513 N, while moving up to a 125 mm bore increases it to 6136 N. The adjustable-stroke window shines when you need to fine-tune a clamping or pressing end position on the machine, or when you want one shared spare across slight stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because this 150 mm stroke is below the 300 mm threshold, side-load risks are minimal, but always guide the load for any longer travel. Add the -S suffix if you need CMSE/DMSE magnetic sensing, as this base model cannot accept a 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 JSIJ100X150-20 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The nominal 150 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 20 mm on-site, yielding a usable forward travel of 130 to 150 mm. The retract end remains fixed. This stop sets the end position and is not a load lock; use an external rod lock or pilot-operated check valve to hold a load, as the cushion only decelerates.
