Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-75S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X275-75S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 275mm 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 JSIJ100X275-75S
The external stop screw lets you trim the usable extend stroke down from the 275 mm maximum to 200 mm without swapping the unit. The hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder.
This double-acting double-rod unit ports at G1/2 and includes a built-in magnet for CMSE/DMSE sensors that drop directly into the side grooves. Adjustable air cushions of 33 mm at each end absorb kinetic energy near stroke end. Remember that the cushion only decelerates the load; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

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 JSIJ100X275-75S Is Used
Press Fit Tuning
Dial in the exact insertion depth of bearings on an assembly line by trimming the extend stroke within the 75 mm window.
Variable Length Diverter
Adjust the extend stop on-site to deflect different carton sizes without repositioning the entire cylinder mount.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X275-75S the Right Cylinder?
The 75 mm adjustable window is ideal when you need to fine-tune end positions on-site or want a single shared spare across slightly different stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. The -S suffix means the magnet is present for CMSE/DMSE switches. Because the 275 mm stroke exceeds 300 mm only marginally, still ensure adequate guide support to prevent side-load wear on the 32 mm 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 JSIJ100X275-75S 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. It uses a G1/2 port.
The 275 mm nominal stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 75 mm, giving a usable extend range of 200-275 mm. The retract end is fixed, and the stop sets position rather than locking the load.
