Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X20-10S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X20-10S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 20mm 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 JSIJ100X20-10S
The extruded hard-anodized aluminium body omits external rods, making it shorter and more compact than a same-bore ISO 15552 unit.
The -10 code means an external stop screw lets you shorten the 20 mm extend stroke on-site by up to 10 mm, giving a usable 10 to 20 mm window without swapping the actuator. Retract remains fixed. A built-in magnet (-S) accepts CMSE/DMSE sensors in the side grooves, and the G1/2 port feeds the 32 mm rod. The stop sets end position only; it is not a load lock.

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 JSIJ100X20-10S Is Used
Heavy Clamping
Apply 3927 N of precise clamping force, fine-tuning the final 10 to 20 mm extend position on-site to suit varying material thicknesses.
Short Pressing
Execute compact pressing operations where the 100 mm bore delivers raw power but the physical stroke must be restricted to a 10 mm window.
Component Seating
Seat heavy mechanical components using the 32 mm rod, relying on the external stop screw to dial in the exact contact depth.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X20-10S the Right Cylinder?
The on-site adjuster is ideal when you share a spare across stroke variants or need fine end-position tuning after mounting. Choose from FA, LB, TC, TCM1, or TCM2 mounts. The -S magnet supports CMSE/DMSE switches. Even at 20 mm stroke, guide external loads to prevent side-load 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 JSIJ100X20-10S 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 max is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 32 mm rod.
The 20 mm nominal stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 10 mm, yielding a 10 to 20 mm usable window. The retract end is fixed. This mechanism sets end position and does not hold load.
