Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X75-10S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X75-10S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 75mm 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 JSIJ100X75-10S
The hard-anodized extruded aluminium profile barrel keeps the assembly clean and rigid without external tie rods. A G1/2 port feeds the double-acting double-rod piston, while adjustable air cushions of 33 mm at each end absorb end-of-stroke shock.
The -10 suffix denotes an external stop screw that lets you shorten the extend stroke on-site by up to 10 mm, giving a usable forward travel of 65 to 75 mm where 75 mm is the maximum. You can fine-tune the end position without swapping the cylinder, which is ideal for shared spares across stroke variants. The -S option equips the piston with a built-in magnet for CMSE or DMSE sensors that mount directly into the side barrel grooves.

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 JSIJ100X75-10S Is Used
Press Clamping
Holds heavy workpieces in a machining fixture, using the 10 mm extend adjuster to dial in the exact clamping position without reprogramming the machine cycle.
Stacking Stopper
Acts as a variable-height stop for incoming cartons, fine-tuning the extend end position by a few millimeters to accommodate different box sizes on the fly.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X75-10S the Right Cylinder?
When sizing this actuator, stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, whereas moving up to a 125 mm bore raises it to 6136 N. The adjustable-stroke window shines when you need on-site end-position tuning across machines that share a common spare, letting one 75 mm nominal unit cover slight variations. Mounting choices include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the -S magnet is present, you can fit reed or electronic switches for position feedback. For any stroke length of 300 mm or longer, always guide the load externally to prevent side-load wear on the rod seals.
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 JSIJ100X75-10S FAQ
The theoretical maximum is 801 kgf at 1.0 MPa. This 100 mm bore unit uses a G1/2 air port and a M26x1.5 rod-end thread.
The 75 mm stroke is the maximum forward travel. An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, yielding a usable range of 65 to 75 mm. The retract end remains fixed. This stop only sets the end position; it does not lock the load, so you need an external rod lock or pilot-operated check valve to hold a load against air loss.
