Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-40S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X700-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 700mm 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 JSIJ100X700-40S
The hard-anodized aluminum extruded barrel skips external rods, and the G1/2 port handles the high air flow needed for the 32 mm piston rod. An external stop screw lets you trim the extend stroke by up to 40 mm on site, giving a usable range of 660 to 700 mm without swapping the cylinder.
Because the nominal 700 mm stroke is the maximum, you can fine-tune the end position to dial in a process exactly. The built-in magnet works with CMSE/DMSE sensors in the side grooves for precise positioning. Remember that the adjustable stop sets the end position but does not lock the load; you need an external rod lock or pilot-operated check valve to hold a load securely 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 JSIJ100X700-40S Is Used
Press Stroke Tuning
Dial in the exact 660 to 700 mm extend position on a large press line using the external adjuster to accommodate material thickness variations without changing the cylinder.
Vertical Load Lowering
Lower a 200 kg vertical payload smoothly using the 33 mm adjustable air cushions at both ends, knowing the fixed retract end ensures a consistent home position.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-40S the Right Cylinder?
The 40 mm adjustable extend window is ideal for sharing a spare across slightly different stroke variants or tuning a final end position on the machine. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. The -S suffix means the piston magnet is present for CMSE/DMSE switches. Because the 700 mm stroke is long, always support the rod against side loads and use external guides to prevent 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 JSIJ100X700-40S 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 force is 801 kgf at 1.0 MPa. This 100 mm bore unit uses a G1/2 port and a 32 mm rod with an M26x1.5 thread.
The nominal 700 mm stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke by up to 40 mm on site, giving a usable range of 660 to 700 mm. The retract end remains fixed. This mechanism only sets the end position; it does not lock the load, so you need a pilot-operated check valve for load holding.
