Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-75
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 225mm 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 JSIJ80X225-75
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder features an external adjuster that shortens the extend stroke on-site by up to 75 mm. The nominal 225 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. Its hard-anodized aluminium barrel omits external rods, making the body shorter and more compact than a same-bore ISO 15552 unit. Equipped with a G3/8 port and M22x1.5 rod thread, it handles about 1508 N of real work safely, lifting roughly 128 kg vertically with a 2:1 margin.
The 29 mm adjustable air cushions at both ends absorb kinetic energy near the stroke limits, but they only decelerate the piston and do not lock the load. If your application requires held positioning on air loss, fit an external rod lock or a pilot-operated check valve. Note that this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors; choose the -S variant if you need position detection.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-75 Is Used
End-Position Trimming
Dial in the exact extend stop on a machining fixture by shortening the 225 mm stroke up to 75 mm, avoiding the need to machine custom spacers.
Variable Length Diverter
Adjust the reach of a sorting gate on the fly to accommodate different package sizes without removing the cylinder from the frame.
Shared Spare Actuator
Keep one actuator in maintenance stock and rotate it across multiple machines, using the external screw to match the specific 150 to 225 mm travel requirement on-site.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X225-75 the Right Cylinder?
When sizing this model, the 63 mm bore offers 1559 N push at 0.5 MPa for lighter duties, while the 100 mm bore steps up to 3927 N for heavier loads. The -75 mm adjuster is particularly useful when you need to share a single spare cylinder across several stroke variants or dial in a precise end position on the machine. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because the 225 mm stroke generates side-load leverage, always guide the load to prevent rod binding. Remember that this non-magnetic version cannot host reed switches.
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 JSIJ80X225-75 FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it delivers 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa. This 80 mm bore unit uses a G3/8 port and an M22x1.5 rod thread.
The external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable extend range of 150 to 225 mm. The nominal 225 mm stroke is the maximum travel, and the retract end remains fixed. This mechanism sets the end position and does not lock the load.
