Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-20
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X100-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm 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 JSIJ63X100-20
The hard-anodized aluminum profile barrel keeps the total envelope shorter than a same-bore ISO 15552 unit, saving valuable machine space without losing power. A G3/8 port supplies air, while adjustable cushions at both ends absorb end-of-stroke impact.
The external adjuster lets you trim the extend stroke by up to 20 mm, yielding a usable range of 80 to 100 mm without changing the cylinder itself. Note this SKU lacks a magnet and cannot take a CMSE/DMSE sensor; add the -S variant for position detection.

Theoretical Output Force (Ø63mm)
| 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 JSIJ63~80 Adjustable Cylinder JSIJ63X100-20 Is Used
Press Fit Tuning
Dial in the exact 80 to 100 mm extend position on-site to seat bearings without bottoming out the tooling.
Variable Stroke Divert
Adjust the extend stop to push varying package widths onto a secondary line without swapping cylinders.
Pallet Stop Adjustment
Fine-tune the retract stop distance on the fly to accommodate different pallet depths arriving at a station.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-20 the Right Cylinder?
The -20 mm adjustable window is perfect for fine-tuning end positions or sharing a spare across 80 to 100 mm stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. For any stroke at or over 300 mm, use a guide rail to prevent rod side-loading. Remember this non-magnetic SKU cannot support sensors; choose the -S version if you need CMSE/DMSE switches.
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 JSIJ63X100-20 FAQ
At 0.5 MPa it pushes 1559 N and pulls 1402 N. At 0.7 MPa it pushes 2182 N and pulls 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa. The air port is G3/8.
The nominal 100 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 20 mm, giving a usable extend range of 80 to 100 mm. The retract end is fixed. This mechanism only sets the end position and does not lock the load.
