Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-50
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-50 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 80mm 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 JSIJ80X80-50
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore pneumatic actuator brings precise on-site end-position tuning to heavy machinery. The external stop screw provides a 50 mm window to shorten the extend stroke, letting you dial in the exact 30 to 80 mm travel without swapping the cylinder. Built to JIS standards with an extruded hard-anodized aluminum profile barrel, it is noticeably 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.
Air connects via a G3/8 port, driving a 25 mm piston rod with an M22x1.5 thread at 30 to 800 mm/s. Adjustable air cushions of 29 mm at each end absorb impact. Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors. Remember that the stop screw sets the end position only; it is not a load lock, so fit an external rod lock or pilot-operated check valve if you need to hold a load against gravity on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-50 Is Used
Press Stroke Tuning
Dial in the exact 30 to 80 mm clamping travel on a stamping line using the external adjuster, avoiding cylinder swaps when material thickness changes.
Divertor Arm Positioning
Fine-tune the extend reach of a sorting gate by up to 50 mm on-site to perfectly match new product widths without reprogramming the machine.
Pallet Stop Adjustment
Shorten the extend stroke to accommodate mixed pallet depths, using the 2513 N push force to halt heavy loads reliably before the retract cycle.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X80-50 the Right Cylinder?
When sizing this 80 mm bore, compare it against the adjacent 63 mm and 100 mm options. The 63 mm yields 1559 N push at 0.5 MPa, while the 100 mm provides 3927 N, giving you clear stepping stones for force scaling. The 50 mm adjuster window is ideal for sharing a single spare cylinder across multiple stroke variants or fine-tuning a final press position on-site. JSIJ mounting choices include Basic, FA, LB, TC, TCM1, and TCM2. If your application involves any stroke length over 300 mm, always use a external guide rail to prevent side-load damage to the rod seals.
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 JSIJ80X80-50 FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa the push is 3518 N and pull is 3175 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
The nominal 80 mm stroke is the maximum travel. The external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 30 to 80 mm. The retract end remains fixed.
