Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X50-10S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X50-10S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 50mm 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 JSIJ100X50-10S
The hard-anodized aluminum profile barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 cylinder. A G1/2 port feeds the chamber, while the -S suffix means a built-in magnet is ready for CMSE or DMSE sensors.
The -10 code defines a 10 mm external adjuster window that shortens the extend stroke on site, giving a usable forward travel of 40 to 50 mm. You fine-tune the stop without swapping the cylinder, and the retract end remains fixed. Note that a plain cylinder drifts on air loss; the adjustable air cushion only decelerates the 33 mm stroke end, so fit an external rod lock or pilot-operated check valve if you need to hold a load.

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 JSIJ100X50-10S Is Used
Press Tooling Trim
Dial in the exact 40 to 50 mm forward reach on a stamping line using the external adjuster to set the precise forming depth without changing the fixture.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X50-10S the Right Cylinder?
The 10 mm extend-shortening window is perfect when you need to share a spare cylinder across slightly different stroke variants or trim a tooling reach on site. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because this SKU includes the -S magnet, you can drop CMSE or DMSE reed or electronic switches directly into the side grooves. For any stroke at or above 300 mm, always use a guide rail to prevent side-load damage to 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 JSIJ100X50-10S 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 force is 801 kgf at 1.0 MPa. The air port is G1/2.
The -10 code provides a 10 mm external adjuster window. The nominal 50 mm extend stroke is the maximum, but you can shorten the forward travel by up to 10 mm on site, yielding a usable range of 40 to 50 mm. The retract end is fixed.
