Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-40S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-40S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm 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 JSIJ80X50-40S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS actuator features an extruded hard-anodized aluminum profile barrel that is noticeably shorter than a same-bore ISO 15552 cylinder. The integrated -S piston magnet allows CMSE or DMSE switches to drop directly into the side grooves for precise position detection. It connects via a G3/8 port and moves a 25 mm rod with an M22x1.5 thread.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, dropping the usable forward travel from the 50 mm maximum down to 10 mm without swapping the cylinder. This on-site tuning handles about 1508 N of real work safely, roughly 128 kg lifted vertically. Remember that a plain cylinder does not hold load on air loss; the 29 mm adjustable air cushions only decelerate near the ends, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended weight.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-40S Is Used
Press Stroke Tuning
Dial in the exact 10 to 50 mm clamping reach on-site via the external stop screw to accommodate varying material thicknesses without changing the actuator.
Transfer Diverter
Set a precise extend position to deflect packages of different sizes on a line, using the G3/8 port and 2513 N push force to move heavy goods reliably.
Vertical Lift Stop
Lift roughly 128 kg vertically with a 2:1 margin, adjusting the downward travel limit in place while relying on a check valve to hold the load safely.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-40S the Right Cylinder?
When sizing, 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 if you need more power. The 80 mm bore hits a strong middle ground. The -40 mm adjustable window is ideal for sharing one spare across multiple stroke variants or fine-tuning the end position during machine commissioning. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. The included -S magnet supports electronic and reed sensors. Even at this 50 mm stroke, guide the load if you encounter any side-load; always add a guide rail for any stroke reaching 300 mm or more.
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 JSIJ80X50-40S FAQ
This 80 mm bore cylinder pushes 2513 N and pulls 2268 N at 0.5 MPa. At 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical maximum force is 513 kgf at 1.0 MPa. It uses a G3/8 port, a 25 mm rod, an M22x1.5 rod thread, and 29 mm adjustable air cushions at both ends.
The 50 mm nominal stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 10 to 50 mm. The retract end is fixed, and this stop screw sets the end position rather than locking the load.
