Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-50S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 450mm 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 JSIJ80X450-50S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder features an external adjuster that shortens the extend stroke on-site by up to 50 mm. The hard-anodized aluminum barrel contains no external rods, making the body shorter and more compact than a same-bore ISO 15552 unit. With a nominal 450 mm stroke, you can fine-tune the extend end position anywhere between 400 and 450 mm without swapping the cylinder. The G3/8 port feeds the 25 mm rod, and the built-in magnet (-S) supports CMSE/DMSE sensors in the side grooves.
In practical terms, the bore handles about 1508 N of safe working load, which equates to lifting roughly 128 kg vertically with a 2:1 margin. Adjustable air cushions at both ends absorb kinetic energy near stroke end, but they only decelerate the piston; a plain cylinder cannot hold a load on air loss, so fit an external rod lock or pilot-operated check valve for suspended loads. Operating pressure spans 0.15 to 1.0 MPa, and the M22x1.5 rod thread handles the 3518 N peak push force at 0.7 MPa.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-50S Is Used
Press Fit Tuning
Dial in the exact 400 to 450 mm extend position on-site to seat bearings without bottoming out the tooling.
Variable Transfer Stop
Adjust the external stop screw to change the physical gate position for different pallet sizes on a shared line.
Spare Stroke Consolidation
Keep one 450 mm unit in stock and shorten the extend stroke as needed to cover multiple non-critical downstream machines.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-50S the Right Cylinder?
Size this 80 mm bore against the 63 mm class, which provides 1559 N of push at 0.5 MPa, and the 100 mm class, which yields 3927 N. The JSIJ series mounting options include FA, LB, TC, TCM1, and TCM2. The -50 mm adjuster is ideal when you need to share one spare cylinder across several stroke variants or fine-tune the end position on-site. Because the 450 mm stroke creates a long lever arm, always support the load with an external guide to prevent rod bending and premature seal wear. The -S suffix means a magnet is already integrated for CMSE/DMSE switches.

- ✓ 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 JSIJ80X450-50S FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical maximum force is 513 kgf at 1.0 MPa. The air port is G3/8.
The nominal 450 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 400 to 450 mm. The retract end is fixed, and the stop sets position only; it does not lock the load.
