Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-75
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X450-75 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 JSIJ100X450-75
The hard-anodized aluminum extrusion omits tie rods entirely, shaving length while retaining rigidity. A G1/2 port feeds the chambers, and the unit runs at speeds of 30-800 mm/s.
The -75 code defines an external stop-screw window that lets you shorten the extend stroke on-site by up to 75 mm, dropping the usable forward travel from the 450 mm maximum down to 375 mm without swapping the cylinder. The retract endpoint remains fixed. Note that this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors.

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 JSIJ100X450-75 Is Used
Press Stroke Tuning
Dial in the exact forming depth on a light-duty press by adjusting the extend stroke from 450 mm down to 375 mm directly at the machine.
Pallet Positioning
Shift the stopping point of a heavy pallet loader on-site without disassembling the line, accommodating different pallet heights.
Heavy Lowering Operations
Lower a 200 kg fixture smoothly using the 33 mm adjustable air cushions at both ends, tweaking the final landing position via the external screw.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-75 the Right Cylinder?
The on-site adjustability is a major advantage when you need to fine-tune an end position after installation or want a single spare part to cover several stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the 450 mm stroke creates leverage, external guide rails are recommended to prevent rod bending under side loads. For position feedback, you must select the -S magnet version to use CMSE or DMSE switches.
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 JSIJ100X450-75 FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable forward travel range of 375-450 mm while the retract end stays fixed. This mechanism only sets the end position; it is not a lock. The cylinder will drift on air loss, so use an external rod lock or pilot-operated check valve for held loads.
