Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-20FA
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-20FA is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 100mm stroke, G3/8 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 JSIJ63~80 Adjustable Cylinder JSIJ80X100-20FA
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site extend tuning to heavy automation. The extruded hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin.
An external adjuster lets you shorten the extend stroke by up to 20 mm on-site, giving a usable 80-100 mm range while the retract end stays fixed. This means you can fine-tune the end position without swapping the cylinder. The G3/8 port feeds the 25 mm rod, and since this SKU lacks the -S magnet, it cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-20FA Is Used
Press Fit Tuning
Dial in the exact 95 mm extend stop for seating bearings without reprogramming the machine cycle.
Divertor Adjustment
Shift the extend end position by a few millimeters on-site to accommodate different package widths.
Pallet Stop Gate
Use the FA foot mount to secure the 2513 N thrust while tweaking the gate reach for varied pallet depths.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X100-20FA the Right Cylinder?
Size this 80 mm bore against the 63 mm class, which offers 1559 N push at 0.5 MPa, or step up to the 100 mm bore for 3927 N if your payload exceeds 1508 N. The -20 mm adjustable window is ideal when you need to share a spare across stroke variants or dial in a final end position on the machine. The FA foot mounting accessory is present, alongside basic, LB, TC, TCM1, and TCM2 options. For any stroke at or over 300 mm, guide the load externally to prevent side-load damage. Remember that a plain cylinder drifts on air loss; the cushions only decelerate, so fit an external rod lock or pilot-operated check valve to hold a load.
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 JSIJ63~80 Adjustable Cylinder JSIJ80X100-20FA FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical max force is 513 kgf at 1.0 MPa. This 80 mm bore unit uses a G3/8 port and a 25 mm piston rod.
The nominal 100 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 20 mm on-site, yielding a usable 80-100 mm range. The retract end remains fixed, and this stop only sets position; it is not a load lock.
