Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-75
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X100-75 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 JSIJ63X100-75
The extruded hard-anodized aluminium barrel omits external rods, leaving a smooth body that is physically shorter and more compact than a same-bore ISO 15552 unit. A G3/8 port feeds the 20 mm piston rod, while adjustable 29 mm air cushions bookend each stroke.
The external stop screw lets you trim the extend stroke on-site by up to 75 mm, dropping the usable forward travel from the 100 mm maximum down to 25 mm without swapping the actuator. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

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 JSIJ63X100-75 Is Used
Press Fit Tuning
Dial in the exact 25 to 100 mm extend position for pressing bearings without machining custom spacers.
Variable Diverter Gate
Adjust the pusher reach on-site to deflect different package sizes on a single sorting line.
Adjustable Sealing Jaw
Shift the extend stop to accommodate various carton depths while maintaining fixed retract spacing.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X100-75 the Right Cylinder?
The 75 mm adjust window is ideal when you need to fine-tune the extend end position across multiple fixtures or share one spare across stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this non-magnetic SKU lacks a piston magnet, it cannot accept position sensors. For any stroke at or over 300 mm, always guide the load to prevent side-load damage to the rod seals.
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 JSIJ63X100-75 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. The G3/8 port and 20 mm rod support these outputs.
The nominal 100 mm extend stroke is the maximum. An external stop screw lets you shorten the forward travel on-site by up to 75 mm, leaving a usable extend range of 25 to 100 mm. The retract end is fixed. This stop only sets position; it is not a load lock.
