Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-40S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-40S 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 JSIJ80X350-40S
Generating 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site flexibility to heavy pneumatics. The extruded hard-anodized aluminium barrel omits tie rods entirely, leaving a clean profile that is physically shorter and more compact than a same-bore ISO 15552 unit. A G3/8 port feeds the 25 mm rod to deliver 3518 N at 0.7 MPa.
The -40 code means an external adjuster can shorten the extend stroke by up to 40 mm, giving a usable 310-350 mm range while the retract end stays fixed. You can fine-tune the end position without remounting the cylinder. The -S suffix adds a piston magnet for CMSE/DMSE sensors in the side grooves. It handles about 1508 N of real work safely, roughly 128 kg lifted vertically.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-40S Is Used
Press Stroke Tuning
Dial in the exact 310-350 mm extend reach on a light assembly press without swapping the cylinder, using the external adjuster to set the precise impact depth.
Variable Length Diverter
Actuate a routing flap on a packaging line where box sizes change, shortening the extend stroke by up to 40 mm on-site to accommodate different package depths.
Adjustable Stop Gate
Control a heavy pallet stop gate, relying on the 2513 N push force at 0.5 MPa to halt loads while fine-tuning the gate position to match pallet dimensions.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-40S the Right Cylinder?
An 80 mm bore sits in the heavy-duty tier, stepping up from the 63 mm bore (1559 N push at 0.5 MPa) and below the 100 mm bore (3927 N). If your load only needs 1500 N, dropping to 63 mm saves space. The adjustable 310-350 mm window is ideal when you need to dial in a final reach on-site or want one shared spare for slightly different stroke machines. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 350 mm stroke creates leverage, always use external guides to prevent rod bending under side loads. The built-in magnet supports CMSE/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 JSIJ80X350-40S FAQ
This 80 mm bore cylinder uses a G3/8 port. It delivers 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum of 513 kgf at 1.0 MPa.
The nominal 350 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 40 mm on-site, yielding a 310-350 mm usable range. The retract end is fixed. This mechanism sets the end position and does not lock the load.
