Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-50
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X450-50 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 450mm 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 JSIJ100X450-50
The hard-anodized aluminium extruded barrel contains no external tie rods, and the G1/2 port feeds a 32 mm rod with an M26x1.5 thread.
The JSIJ100X450-50 uses an external stop screw to shorten the extend stroke on-site by up to 50 mm, giving a usable forward travel of 400-450 mm while the retract end remains fixed. You can fine-tune the end position without swapping the cylinder, and adjustable 33 mm air cushions at both ends decelerate the payload smoothly. Note that this SKU lacks a magnet and cannot take CMSE/DMSE sensors; for the switchable version you need the -S variant. Because the 450 mm stroke invites rod bending, always support the load with an external guide.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|

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 JSIJ100X450-50 Is Used
Press Tonnage Trimming
Dial in the exact 410 mm extend stop on a forming press to accommodate different material thicknesses without changing the entire actuator setup.
Pallet Positioning Gate
Adjust the forward stroke by up to 50 mm on-site to align heavy 200 kg pallet loads precisely against a conveyor stop before transfer.
Heavy Lowering Assembly
Lower heavy machinery sub-assemblies smoothly using the 33 mm adjustable cushions, tweaking the end position to meet varying mating heights.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-50 the Right Cylinder?
When sizing this unit, stepping down to the 80 mm bore drops the 0.5 MPa push force to 2513 N, while stepping up to the 125 mm bore raises it to 6136 N. The 50 mm adjuster window is ideal for sharing one spare cylinder across several stroke variants or dialing in a final end position on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. This specific SKU has no magnet, so it cannot accept position sensors; choose the -S version if you require CMSE or DMSE switches. With a 450 mm stroke, external guiding is mandatory to prevent rod bending and premature seal wear from side 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 JSIJ100X450-50 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 force is 801 kgf at 1.0 MPa. The air port is G1/2.
The nominal 450 mm stroke is the maximum forward travel. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, yielding a usable range of 400-450 mm. The retract end is fixed, and this stop only sets position—it does not lock the load.
