Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-30S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X100-30S 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 JSIJ63X100-30S
The extruded hard-anodized aluminum barrel keeps the total envelope short, and the G3/8 port matches the bore's air demand. Because the stop mechanism only decelerates the piston near the end of travel, you will need an external rod lock or pilot-operated check valve if the assembly must hold a load on air loss.
The -30S code means an external adjuster can shorten the extend stroke on site by up to 30 mm, giving a usable extend range of 70 to 100 mm without changing the cylinder itself. This on-site tuning is ideal for dialing in a precise end position, and the built-in magnet works with CMSE/DMSE sensors in the side grooves for position feedback.

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 JSIJ63X100-30S Is Used
Press Fit Dialing
Fine-tune the 70 to 100 mm extend stroke on site to set precise pressing depth for bearing insertion without swapping cylinders.
Variable Transfer Stop
Adjust the external stop screw to alter the extend position on the fly, accommodating different package sizes on a single line.
Compact Divert Arm
Leverage the shorter JIS profile length to fit a diverting arm into a tight conveyor gap while using the magnet for end confirmation.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-30S the Right Cylinder?
The adjustable stroke shines when you want one shared spare for several stroke variants or need to fine-tune the extend end position on the floor. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet supports CMSE/DMSE switches. For any stroke at or over 300 mm, always guide the load to prevent rod 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 JSIJ63~80 Adjustable Cylinder JSIJ63X100-30S 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 is 318 kgf at 1.0 MPa. The air port is G3/8.
The nominal 100 mm extend stroke is the maximum. The external adjuster lets you shorten the extend stroke on site by up to 30 mm, yielding a usable range of 70 to 100 mm. The retract end remains fixed.
