Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X200-40S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X200-40S 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 JSIJ100X200-40S
The hard-anodized aluminum barrel keeps the build light, and the G1/2 port handles the air volume needed for high thrust. A built-in magnet (-S) lets you drop CMSE or DMSE reed and electronic switches directly into the side grooves for precise position detection.
The -40 code means an external adjuster can shorten the 200 mm extend stroke on-site by up to 40 mm, giving a usable range of 160 to 200 mm without swapping the cylinder. This on-site tuning is ideal for dialing in end positions, and the retract end remains fixed. Note that the adjustable stop sets the end position but does not lock the load; a pilot-operated check valve or external rod lock is required for holding against air loss.

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 JSIJ100X200-40S Is Used
Press Fit Tuning
Dial in the exact 160 to 200 mm insertion depth for bearing presses on-site using the external adjuster without changing the cylinder.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X200-40S the Right Cylinder?
When sizing this 100 mm bore unit, stepping down to an 80 mm cylinder drops the 0.5 MPa push force to 2513 N, whereas moving up to a 125 mm bore increases it to 6136 N. The adjustable stroke feature is highly useful when you need to fine-tune a 160 to 200 mm end position on the machine or want to standardize one spare across multiple stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The integrated -S magnet supports CMSE/DMSE sensors. Because the stroke is 200 mm, always guide the load to prevent excessive side loading on 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 JSIJ100X200-40S FAQ
The theoretical maximum force is 801 kgf at 1.0 MPa. It features a 100 mm bore, a 32 mm rod, a G1/2 port, and M26x1.5 rod threads. The operating speed ranges from 30 to 800 mm/s.
The nominal stroke is 200 mm, which is the maximum extend length. The -40 code means an external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 160 to 200 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
