Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X160-20S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X160-20S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 160mm 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 JSIJ100X160-20S
The hard-anodized aluminum extruded barrel contains no external tie rods, keeping the body smooth and rigid. A G1/2 port supplies air, driving a 32 mm rod with M26x1.5 threading at speeds of 30-800 mm/s.
The -20 code marks an external adjuster that lets you shorten the extend stroke by up to 20 mm on-site, giving a usable forward range of 140-160 mm while the retract end stays fixed. Because this SKU includes the -S magnet, it accepts CMSE or DMSE sensors in the side grooves for position detection.

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 JSIJ100X160-20S Is Used
Press Fit Tuning
Use the 20 mm extend adjuster to dial in the exact seating depth of bearings or pins on-site without changing the cylinder body.
Vertical Lift Dampener
Lower loads up to 200 kg safely, relying on the 33 mm adjustable air cushions at both ends to decelerate the 160 mm travel smoothly.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X160-20S the Right Cylinder?
The adjustable stroke is ideal for sharing one spare across stroke variants or finalizing end positions during machine commissioning. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. For any stroke at or over 300 mm, always use a guide to prevent rod side-load damage. Remember that a plain cylinder drifts on air loss; fit an external rod lock or pilot-operated check valve if the load must be held.
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 JSIJ100X160-20S 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 is 801 kgf at 1.0 MPa. The air port is G1/2.
The nominal 160 mm extend stroke is the maximum. The external adjuster lets you shorten the forward stroke by up to 20 mm on-site, giving a usable range of 140-160 mm. The retract end is fixed, and this stop only sets position; it does not lock the load.
