Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-100
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X350-100 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 350mm 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 JSIJ63X350-100
The hard-anodized aluminum barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit. A G3/8 port feeds the chamber, while adjustable 29 mm air cushions at both ends absorb kinetic energy near the end of travel.
The -100 suffix denotes an external adjuster that shortens the extend stroke by up to 100 mm on site, yielding a usable forward travel of 250-350 mm without swapping the actuator. Note this plain SKU lacks a magnet and cannot accept CMSE/DMSE sensors. The retract end remains fixed, and the adjuster sets end position rather than locking the load.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 kgf | |
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 JSIJ63X350-100 Is Used
Transfer Line Diverter
Fine-tune the 250-350 mm extend reach on-site to push varying carton widths off a main conveyor without changing the cylinder mount.
Press Pin Insertion
Dial in the exact 63 mm bore forward stop for seating pins, using the 100 mm adjuster window to compensate for fixture height differences.
Pallet Stopper Gate
Adjust the extend stroke to act as a movable stop for pallets, retracting to clear the load while relying on the fixed retract end.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-100 the Right Cylinder?
When sizing this model against its neighbors, stepping down to a 50 mm bore drops the 0.5 MPa push force to 982 N, whereas stepping up to an 80 mm bore raises it to 2513 N. The 63 mm bore sits in a versatile mid-range, and the 100 mm adjuster window lets you fine-tune the extend end position on-site, making one spare actuator viable across multiple stroke variants. Mounting choices cover Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this SKU lacks the -S magnet, it cannot host CMSE or DMSE switches. Finally, with a 350 mm stroke, always support the load with external guides to prevent rod bending and excessive 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 JSIJ63X350-100 FAQ
The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 port and a 20 mm rod with an M18x1.5 thread.
The -100 indicates an external adjuster that lets you shorten the extend stroke by up to 100 mm on site. The usable forward travel becomes 250-350 mm, with the 350 mm nominal stroke acting as the maximum. The retract end is fixed. This mechanism only sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve if you need to hold a load against air loss.
