Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-50
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-50 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 275mm 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 JSIJ80X275-50
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore pneumatic actuator brings on-site flexibility to demanding setups. The external stop screw provides a 50 mm extend-shortening window, allowing you to fine-tune the end position anywhere between 225 and 275 mm without swapping the cylinder. Its hard-anodized aluminum profile barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. It handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin.
This double-acting single-rod JIS variant features a 25 mm piston rod, an M22x1.5 rod-end thread, and a G3/8 air port. Adjustable air cushions of 29 mm at each end absorb kinetic energy near the stroke limits. Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors for position detection. Remember that the adjustable stop sets the end position but does not lock the load; you will need an external rod lock or pilot-operated check valve to hold a suspended weight securely on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-50 Is Used
Press Stroke Tuning
Dial in the exact 225 to 275 mm extend distance on a light assembly press to accommodate different material thicknesses without changing the actuator.
Variable Transfer Stops
Act as an adjustable flight stop on a conveyor line, shortening the extend stroke by up to 50 mm to handle varying package sizes on the fly.
Compact Divert Gates
Fit a robust 80 mm bore diverter gate in tight machinery footprints, leveraging the shorter JIS profile body where ISO 15552 units would not clear.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X275-50 the Right Cylinder?
When sizing this model, the 80 mm bore sits comfortably in the mid-to-high force range, offering 2513 N push at 0.5 MPa. If your application requires less force, stepping down to a 63 mm bore yields 1559 N, while moving up to a 100 mm bore provides 3927 N. The 50 mm adjustable window is particularly useful for sharing a single spare cylinder across multiple machines that need slightly different extend lengths. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. Since the 275 mm stroke exceeds 300 mm only slightly, guide any side loads carefully to prevent rod bending, and note that without the -S suffix, magnetic sensing is impossible.
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 JSIJ80X275-50 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. The air port size is G3/8.
An external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 225 to 275 mm. The nominal 275 mm is the maximum, and the retract end remains fixed. This mechanism sets the end position but does not function as a load lock.
