Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-40S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-40S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 800mm 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 JSIJ80X800-40S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for heavy-duty positioning. Its extruded hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port matches the bore size, and the M22x1.5 rod thread handles substantial loads.
The -40 code means an external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 760-800 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. The -S suffix adds a built-in piston magnet for CMSE/DMSE switches in the side grooves. In practice it handles about 1508 N of real work, roughly 128 kg lifted vertically. Note that the cushion only decelerates; use an external rod lock for held loads.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-40S Is Used
Pallet Diverting
Tunes the extend stop on-site to 760 mm for diverting varied pallet sizes without repositioning the whole cylinder assembly.
Press Dwell Control
Adjusts the extend end-position by up to 40 mm to set precise dwell depth on light assembly presses without changing the fixed retract.
Vertical Lift Stops
Lifts roughly 128 kg vertically and fine-tunes the upper stop position to accommodate different package heights on the fly.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-40S the Right Cylinder?
Size this 80 mm bore against the 63 mm (1559 N push @0.5 MPa) and 100 mm (3927 N push @0.5 MPa) options to match your force needs. The adjustable stroke shines when you need on-site end-position tuning across shared spare units. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet enables CMSE/DMSE sensor integration. Because the stroke is 800 mm, 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 JSIJ80X800-40S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it delivers 3518 N push and 3175 N pull. The theoretical max force is 513 kgf at 1.0 MPa. This 80 mm bore cylinder uses a G3/8 port and features a 25 mm rod with an M22x1.5 thread.
The nominal stroke is 800 mm, which is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable extend range of 760-800 mm. The retract end remains fixed. This mechanism sets the end position and does not lock the load.
