Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X250-100
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X250-100 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 250mm 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 JSIJ100X250-100
The extruded hard-anodized aluminum profile barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 cylinder, saving valuable machine space. It feeds air through a G1/2 port and runs at 30-800 mm/s.
The -100 code means an external stop screw lets you shorten the extend stroke on-site by up to 100 mm, giving a usable forward range of 150 to 250 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder, and a shared spare can cover multiple stroke variants. Note this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors.

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 JSIJ100X250-100 Is Used
Press Fit Tuning
Dial in the exact 150 to 250 mm extend reach on-site to seat bearings without over-traveling or crushing the workpiece.
Variable Transfer Stop
Adjust the external stop screw to change the package halt position on the fly for mixed product sizes on a single line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X250-100 the Right Cylinder?
The adjustable window shines when you need on-site end-position tuning or want a single spare for several stroke lengths. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 250 mm stroke exceeds 300 mm only slightly, keep an eye on side loads and use a guide rail to prevent rod bending.
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 JSIJ100X250-100 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. It uses a G1/2 air port and features a 33 mm adjustable air cushion at each end.
The nominal 250 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 100 mm, yielding a usable range of 150 to 250 mm. The retract end is fixed. This mechanism sets the end position but does not hold the load on air loss; for that you need an external rod lock or pilot-operated check valve.
