Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-40S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X350-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 350mm 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 JSIJ100X350-40S
The extruded hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit. A G1/2 port feeds the 32 mm piston rod, while adjustable air cushions of 33 mm absorb impact at both ends.
The -40 code means an external adjuster can shorten the extend stroke on-site by up to 40 mm, giving a usable 310-350 mm range while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder, and the -S suffix adds a piston magnet for CMSE/DMSE switches in the side grooves.

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 JSIJ100X350-40S Is Used
Press Stroke Tuning
Dial in the exact 310-350 mm extend reach on a light assembly press without machining new spacers or changing the actuator.
Pallet Stopper Adjustment
Accommodate varying pallet heights by shortening the extend stroke 40 mm on-site, ensuring positive stops at the correct depth.
Diverter Gate Positioning
Fine-tune the gate extension endpoint to route different package sizes accurately on a high-throughput line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X350-40S the Right Cylinder?
When sizing this actuator, stepping down to an 80 mm bore drops the 0.5 MPa push force to 2513 N, whereas moving up to 125 mm raises it to 6136 N. The adjustable stroke is ideal for sharing one spare across multiple stroke variants or dialing in a final end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet supports CMSE/DMSE sensors for position confirmation. Because the 350 mm stroke is long, always use external guides to prevent rod bending and manage side loads.
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 JSIJ100X350-40S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa the push is 5497 N and the pull is 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 32 mm rod.
The nominal 350 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 40 mm on-site, yielding a usable 310-350 mm range. The retract end is fixed. This mechanism sets the end position and does not lock the load.
