Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-30
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X100-30 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 JSIJ63X100-30
The hard-anodized aluminum barrel contains no external rods, making the overall body shorter and more compact than a same-bore ISO 15552 unit.
The dash-30 code means an external stop screw lets you shorten the extend stroke by up to 30 mm right at the machine, giving a usable extend range of 70-100 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder, and the G3/8 ports feed adjustable 29 mm air cushions at both ends. Note this plain SKU lacks a magnet and cannot take a sensor; order the -S version for CMSE or DMSE switches.

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 JSIJ63X100-30 Is Used
Stroke Tuning for Forming
Dial in the exact 70-100 mm extend position on a press without machining new spacers, using the external adjuster to set the precise contact point.
Adjustable Diverter Arm
Fine-tune the pusher reach on a sorting line by shortening the extend stroke up to 30 mm to accommodate different package sizes on the fly.
Shared Spare Inventory
Keep one cylinder in maintenance stock and adjust the extend window on-site to cover multiple 63 mm bore machines with slightly varied stroke needs.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-30 the Right Cylinder?
If 1559 N at 0.5 MPa is too much, step down to the 50 mm bore for 982 N; if you need more power, the 80 mm bore supplies 2513 N. The dash-30 adjuster is ideal when you want a shared spare across slightly different stroke variants or need to dial in the exact end position during commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a 100 mm stroke, side loads are minimal, but for any stroke over 300 mm you should guide the rod to prevent binding. Remember that air cushions only decelerate the piston; for holding a load on air loss, fit an external rod lock or pilot-operated check valve.
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 JSIJ63X100-30 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. The dash-30 means an external stop screw lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 70-100 mm. The retract end is fixed, and the stop sets end position rather than locking the load.
