Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-10S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X300-10S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 300mm 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 JSIJ100X300-10S
The hard-anodized aluminum extruded barrel contains no external tie rods, and the G1/2 port feeds a 32 mm rod with an M26x1.5 thread. Because the -S suffix equips the piston with a magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position sensing.
The -10 code means an external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable forward travel of 290 to 300 mm while the retract end remains fixed. You can fine-tune the end position without physically remounting the cylinder, which is ideal for sharing a spare across stroke variants. The 33 mm adjustable air cushions at both ends decelerate the load smoothly, though 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 JSIJ100X300-10S Is Used
Pallet Diverter
Pushes heavy pallets off a main line, relying on the 33 mm adjustable cushions to stop the 300 mm stroke smoothly without slamming.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X300-10S the Right Cylinder?
When sizing this 100 mm bore unit, stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, while stepping up to 125 mm raises it to 6136 N. The adjustable stroke shines when you need on-site end-position tuning or want a single shared spare for multiple stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The built-in magnet supports CMSE/DMSE sensors. Because the 300 mm stroke creates leverage, always support the rod against side-load bending and use external guides to prevent premature wear.
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 JSIJ100X300-10S 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 is 801 kgf at 1.0 MPa. The air port is G1/2.
The nominal 300 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, yielding a usable forward travel of 290 to 300 mm. The retract end is fixed, and this mechanism sets end position rather than locking the load.
