Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-50S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X175-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 175mm 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 JSIJ100X175-50S
Its extruded hard-anodized aluminium profile barrel ditches external rods for a clean, compact body that is noticeably shorter than a same-bore ISO 15552 cylinder. The G1/2 port feeds the chamber efficiently, while the integrated piston magnet (-S) allows CMSE or DMSE sensors to drop directly into the side grooves for precise position detection.
The external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 125 to 175 mm without swapping the cylinder. This on-site adjustability means you can fine-tune the end position perfectly, and the nominal 175 mm stroke always serves as the maximum.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 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 JSIJ100X175-50S Is Used
Press Tool Tuning
Dial in the exact 125 to 175 mm extend reach on a heavy stamping press without machining new spacers, using the external stop screw to set the precise forming depth.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X175-50S the Right Cylinder?
The adjustable stroke is perfect when you need to tune the extend end position on-site or want a shared spare across slight stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. The -S magnet supports CMSE/DMSE switches. Because the stroke is 175 mm, always guide the load to prevent excessive side-loading on the rod.
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 JSIJ100X175-50S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa.
The external adjuster lets you shorten the extend stroke on-site by up to 50 mm. The usable extend range is 125 to 175 mm, with 175 mm being the fixed maximum nominal stroke. The retract end remains fixed, and this stop is for positioning, not load holding.
