Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-10
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 350mm 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 JSIJ80X350-10
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder integrates an external stop screw that lets you trim the extend stroke by up to 10 mm directly on site. The nominal 350 mm stroke remains the maximum travel, yielding a usable 340-350 mm extend range while the retract end stays fixed. Because it uses an extruded hard-anodized aluminium barrel, the overall body is shorter and more compact than a same-bore ISO 15552 cylinder.
In practical terms the unit handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin. Pneumatically it feeds through a G3/8 port and runs at 30-800 mm/s. Note this specific SKU lacks a magnet, so it cannot take CMSE or DMSE sensors without switching to the -S variant. Also, the adjustable stop only sets the end position; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a load.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-10 Is Used
Conveyor Diverter Trim
Fine-tune the 340-350 mm extend reach by up to 10 mm on-site to perfectly align a diverter gate without remounting the actuator.
Press Head Positioning
Leverage the 2513 N push force to press components, using the external adjuster to dial in the exact bottoming height for different material batches.
Pallet Stop Calibration
Set a precise 350 mm maximum stop for pallets on a line, shortening the stroke by 10 mm on the fly to accommodate varying load overhangs.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-10 the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm drops the 0.5 MPa push force to 1559 N, while moving up to a 100 mm bore increases it to 3927 N. The 10 mm adjustable window is ideal for fine-tuning end positions on-site without swapping the cylinder, letting you standardize one spare across slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a 350 mm stroke, you must support the load with external guides to prevent rod bending and side-load damage. This non-magnet model cannot host sensors; order the -S version if you require CMSE or DMSE 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 JSIJ80X350-10 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 air port, features a 25 mm piston rod, and has an M22x1.5 rod-end thread with 29 mm adjustable air cushions at both ends.
The -10 indicates an external adjuster window of 10 mm. The nominal 350 mm stroke is the maximum extend travel, but you can shorten the extend stroke on-site down to 340 mm. The retract end remains fixed. This stop mechanism only sets the end position and does not lock the load; you need an external rod lock or pilot-operated check valve to hold a load securely against air loss.
