Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-50S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X700-50S 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 JSIJ100X700-50S
The hard-anodized aluminum barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit.
The -50 code means the extend stroke can be shortened by up to 50 mm on-site, giving a usable forward range of 650 to 700 mm while the retract end remains fixed. This lets you fine-tune the end position without swapping the cylinder. The G1/2 port feeds the 32 mm rod, and the -S suffix equips the side grooves for CMSE or DMSE sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|

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 JSIJ100X700-50S Is Used
Press Stroke Tuning
Dial in the exact 650 to 700 mm extend position on-site to accommodate different material thicknesses without changing out the entire actuator.
Long-Transfer Diverter
Uses the full 700 mm stroke to shift heavy product lines between parallel conveyors, with the -S magnet confirming reach via CMSE sensors.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X700-50S the Right Cylinder?
The 50 mm adjustable window is ideal for sharing a spare across stroke variants or finalizing end positions during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 700 mm, always use an external guide rail to prevent rod bending and excessive side loads. Remember that the air cushion only decelerates the piston; use an external rod lock or pilot-operated check valve if you need to hold a load vertically.
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 JSIJ100X700-50S 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.
The external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable range of 650 to 700 mm. The nominal 700 mm is the maximum, and the retract end remains fixed. This mechanism sets the end position and is not a load lock.
