Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-50S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 900mm 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 JSIJ80X900-50S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore model brings heavy-duty capacity to applications needing on-site stroke tuning. An external adjuster lets you shorten the extend stroke by up to 50 mm, giving a usable range of 850 to 900 mm without swapping the cylinder. The retract end remains fixed. This works out to a safe working load of about 1508 N, or roughly 128 kg lifted vertically with a 2:1 margin.
Built to JIS standards with an extruded hard-anodized aluminum profile barrel, the unit is physically shorter and more compact than an ISO 15552 cylinder of the same bore. It features a G3/8 port, a 25 mm piston rod, and adjustable air cushions of 29 mm at both ends. The -S suffix means a built-in piston magnet is included for CMSE/DMSE switches. Note that plain cylinders drift on air loss; use an external rod lock or pilot-operated check valve for held loads.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-50S Is Used
Long-Transfer Diverter
Pushes heavy pallets along a 900 mm run, using the 50 mm adjuster to dial in the exact push-off distance without repositioning the cylinder mount.
High-Bay Extractor
Reaches deep into storage racks to pull goods, relying on the 2513 N push force at 0.5 MPa to handle substantial tote weights reliably.
Large-Part Press Stand
Deploys a 900 mm stroke to lower a forming tool, fine-tuning the final 50 mm of extend position to accommodate different material thicknesses.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X900-50S the Right Cylinder?
When sizing this actuator, compare it against the neighboring 63 mm bore, which offers 1559 N of push at 0.5 MPa, and the 100 mm bore, which pushes 3927 N at the same pressure. The 80 mm bore sits perfectly in the middle for medium-heavy machinery. The 50 mm adjuster window is highly useful when you need to fine-tune an end position across multiple stations or keep a shared spare for slightly different stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 900 mm stroke is quite long, always use external guides to prevent rod bending and manage side loads.
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 JSIJ80X900-50S FAQ
At 0.5 MPa it provides 2513 N of push and 2268 N of pull. 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 air port size is G3/8.
The nominal 900 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, yielding a usable extend range of 850 to 900 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
