Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-10
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-10 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 JSIJ80X50-10
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore pneumatic actuator brings heavy-duty performance to tight machinery layouts. It is a JIS-standard profile cylinder that runs shorter and more compact than a same-bore ISO 15552 unit, built with a hard-anodized aluminum extruded barrel. The G3/8 port feeds a double-acting single rod design rated for 30-800 mm/s speeds.
The JSIJ80X50-10 features an external stop screw that lets you trim the extend stroke by up to 10 mm right on the floor. You get a usable extend range of 40-50 mm, with the 50 mm nominal length acting as the maximum and the retract end fixed. This on-site tuning handles about 1508 N of real work safely, which means roughly 128 kg lifted vertically with a 2:1 margin. Note that this specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-10 Is Used
Press Fit Tuning
Dial in the exact 40-50 mm extend contact point for light-duty press fits without remachining your tooling stops.
Transfer Diverter
Adjust the extend length on-site to perfectly meet varying product sizes on a packaging line diverter arm.
Vertical Spot Weld
Lower a welding head with 2513 N of thrust and easily shorten the stroke window to avoid hitting the anvil.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-10 the Right Cylinder?
When sizing this model, look at the neighboring bores: a 63 mm bore gives 1559 N push at 0.5 MPa for tighter spots, while a 100 mm bore jumps to 3927 N if you need extra margin. The adjustable stroke shines when you need to fine-tune an end position without swapping the whole cylinder, or when you want one shared spare across multiple stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnet SKU, you cannot fit position sensors; add the -S suffix if you need CMSE or DMSE switches. For any stroke at or above 300 mm, always use a guide rail to prevent side-load damage.
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 JSIJ80X50-10 FAQ
This 80 mm bore cylinder uses a G3/8 port and delivers 2513 N push and 2268 N pull at 0.5 MPa. At 0.7 MPa it outputs 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa.
The -10 means an external adjuster can shorten the extend stroke by up to 10 mm on-site. The nominal 50 mm stroke is the maximum, giving you a usable extend range of 40-50 mm, while the retract end remains fixed. This mechanism only sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve if you need to hold a load against air loss.
