Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X40-30S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X40-30S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 40mm 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 JSIJ100X40-30S
The extruded hard-anodized aluminium barrel is noticeably shorter than a same-bore ISO 15552 unit. Air connects via a G1/2 port.
The JSIJ100X40-30S uses an external stop screw to shorten the extend stroke on-site by up to 30 mm. Nominal travel is 40 mm maximum, yielding a usable extend range of 10-40 mm, while the retract end stays fixed. This lets you fine-tune the end position without swapping the cylinder. The -S suffix adds a piston magnet for CMSE/DMSE sensors in the side grooves. Note that a plain cylinder drifts on air loss; the cushions only decelerate, so use an external rod lock for held loads.

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 JSIJ100X40-30S Is Used
Press Fit Tuning
Dial in the exact 10-40 mm extend distance on-site for seating bearings without machining custom spacers.
Pallet Stop Gate
Fine-tune the 40 mm stroke gate position to handle mixed pallet dimensions without repositioning the hard-anodized profile cylinder.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X40-30S the Right Cylinder?
The adjustable stroke is ideal when you need a shared spare across slightly different stroke variants or precise on-site end-position tuning. Mounting options include FA, LB, TC, TCM1, and TCM2. The built-in magnet supports CMSE/DMSE switches. Even at 40 mm stroke, guide the load to prevent side-load wear.
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 JSIJ100X40-30S FAQ
This 100 mm bore cylinder pushes 3927 N and pulls 3574 N at 0.5 MPa. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical max force is 801 kgf at 1.0 MPa. It uses a G1/2 port, a 32 mm rod, and has 33 mm adjustable air cushions at both ends.
The nominal extend stroke is 40 mm maximum. The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 10-40 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
