Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-20S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X500-20S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 500mm 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 JSIJ100X500-20S
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 supplies the air, while adjustable 33 mm cushions absorb kinetic energy at both ends.
The -20 code means an external adjuster can shorten the extend stroke on-site by up to 20 mm, giving a usable 480-500 mm forward travel while the retract end stays fixed. The -S suffix adds a piston magnet for CMSE/DMSE switches that drop directly into 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 JSIJ100X500-20S Is Used
Press Tool Tuning
Dial in the exact 480-500 mm clamping reach on a large press without machining new spacers, using the external adjuster to set the final extend position.
Vertical Load Lowering
Lower a 200 kg fixture smoothly using the 33 mm adjustable air cushions to decelerate the mass near the fixed retract end of the 500 mm travel.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-20S the Right Cylinder?
The adjustable stroke is ideal for sharing a spare across stroke variants or dialing in a precise end stop on-site. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. Because the 500 mm stroke is long, always support the load with an external guide to prevent rod bending and excessive side loading.
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 JSIJ100X500-20S 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 rod is 32 mm with an M26x1.5 thread, and speed ranges 30-800 mm/s.
The nominal 500 mm stroke is the maximum. The external stop screw lets you shorten the extend stroke on-site by up to 20 mm, yielding a usable 480-500 mm forward travel. The retract end is fixed. This mechanism sets the end position but does not lock the load; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.
