Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X50-30
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X50-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 50mm 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 JSIJ63X50-30
The hard-anodized aluminium barrel leaves out external rods, making the body shorter and more compact than a same-bore ISO 15552 unit. A G3/8 port feeds the chamber, while a 29 mm adjustable air cushion decelerates the piston at each end.
The -30 code means an external stop screw can shorten the extend stroke by up to 30 mm on site, giving a usable forward travel of 20 to 50 mm without swapping the cylinder. This on-site end-position tuning lets you share one spare across stroke variants. Note this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 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 JSIJ63X50-30 Is Used
Insertion Depth Tuning
Dial in exact press-fit travel on an assembly line by trimming the extend stroke up to 30 mm on site.
Adjustable Transfer Stop
Act as a variable-height stop gate for mixed-product conveyors, tweaking the 50 mm forward position as needed.
Shared Spare Inventory
Keep one cylinder on the shelf and adjust its forward travel to cover several slightly different machine setups.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X50-30 the Right Cylinder?
The adjustable stroke shines when you need to fine-tune a clamping or insertion depth on the floor, or want a shared spare across slight stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a non-magnetised model, you cannot fit position sensors; move to an -S variant for CMSE or DMSE switches. For any stroke at or over 300 mm, add an external guide rail to prevent side-load wear.
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 JSIJ63X50-30 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 rod is 20 mm with an M18x1.5 thread, and it has a 29 mm cushion.
The nominal stroke is 50 mm. The external adjuster lets you shorten the extend stroke by up to 30 mm on site, yielding a usable forward travel of 20 to 50 mm. The retract end is fixed. This stop sets the end position but does not lock the load; for load holding on air loss, use an external rod lock or pilot-operated check valve.
