Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-50
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X350-50 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 JSIJ63X350-50
The hard-anodized aluminum profile barrel keeps the overall length shorter than a same-bore ISO 15552 unit.
The external adjuster lets you trim the extend stroke by up to 50 mm, dropping the usable forward travel from the 350 mm maximum down to 300 mm without changing the cylinder itself. The retract end remains fixed, and the G3/8 port feeds a 29 mm adjustable air cushion at each end. This plain SKU lacks a magnet, so it 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 JSIJ63X350-50 Is Used
Sorter Diverter Tuning
Fine-tune the 300 to 350 mm extend reach on-site to perfectly match package sizes without swapping the actuator.
Press Load Positioning
Adjust the downstroke end point by up to 50 mm to accommodate different material thicknesses in a compact JIS footprint.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X350-50 the Right Cylinder?
The 50 mm adjustable window is ideal for sharing one spare across multiple stroke variants or fine-tuning the end position on-site. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because the stroke is 350 mm, always use an external guide to prevent rod bending under side loads. Note that a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a load.
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 JSIJ63X350-50 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. It uses a G3/8 port and a 20 mm rod.
The -50 code means an external stop screw lets you shorten the extend stroke by up to 50 mm on-site. The usable forward travel becomes 300 to 350 mm, with 350 mm being the maximum. The retract end is fixed, and this stop only sets the end position, not a load lock.
