Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X200-20S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X200-20S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 200mm 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 JSIJ100X200-20S
Its extruded hard-anodized aluminum barrel is noticeably shorter than a same-bore ISO 15552 unit, saving valuable machine space. The G1/2 port feeds the chamber efficiently, while the built-in magnet (-S) allows CMSE or DMSE sensors to drop directly into the side grooves for precise position detection.
The external adjuster lets you shorten the extend stroke on-site by up to 20 mm, giving a usable range of 180 to 200 mm without swapping the cylinder. This on-site tuning means you can fine-tune the end position perfectly, and a single spare can cover several stroke variants.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 N |
| Max (@1.0 MPa) | 719 kgf | |
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 JSIJ100X200-20S Is Used
Press Tonnage Trimming
Use the 20 mm extend window to precisely trim the bottom-dead-center position on a light pneumatic press without machining new spacers.
Dynamic Transfer Stops
Adjust the stopping point on the fly for mixed product sizes on a heavy-duty conveyor line, ensuring exact 180 to 200 mm extension.
Pallet Positioning Gates
Fine-tune the gate actuation distance on-site to accommodate varying pallet widths while maintaining high force for heavy loads.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X200-20S the Right Cylinder?
The adjustable stroke is ideal for sharing a spare across stroke variants or finalizing end positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix means a magnet is already included for CMSE/DMSE switches. For any stroke over 300 mm, always use a guide to prevent rod side-loading.
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 JSIJ100X200-20S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 33 mm adjustable air cushion at each end.
The nominal 200 mm stroke is the maximum length. The external stop screw lets you shorten the extend stroke by up to 20 mm on-site, giving a usable extend range of 180 to 200 mm. The retract end remains fixed. This stop only sets the end position and does not lock the load.
