Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-40
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-40 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 JSIJ80X450-40
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is shorter and more compact than a same-bore ISO 15552 unit. The hard-anodized aluminum barrel keeps the build clean while the G3/8 port feeds the 25 mm rod. It handles about 1508 N of real work safely, which means roughly 128 kg lifted vertically with a 2:1 margin.
The -40 code means an external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 410-450 mm without changing the cylinder itself. The retract end remains fixed. This plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor. Note that air cushions only decelerate the piston; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve to hold a suspended load.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-40 Is Used
Stopper Gate Tuning
Dial in the exact 410-450 mm extend position to halt pallets on a conveyor line without swapping the whole cylinder.
Press End-Position Trim
Fine-tune the downstroke contact point on a light assembly press by adjusting the external stop screw on-site.
Shared Spare Stock
Keep one cylinder as a plant-wide spare and shorten its extend stroke up to 40 mm to fit various 80 mm bore machines.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X450-40 the Right Cylinder?
When sizing, the neighboring 63 mm bore gives 1559 N push at 0.5 MPa while the 100 mm bore jumps to 3927 N, so this 80 mm sits firmly in the mid-heavy range. The adjustable stroke is ideal for sharing a spare across stroke variants or fine-tuning the extend end position on-site. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 450 mm stroke is long, always use external guides to prevent rod bending and side-load damage. Remember this no-magnet SKU cannot accept a sensor.
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 JSIJ80X450-40 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 max is 513 kgf at 1.0 MPa. It uses a G3/8 port and a 25 mm rod with an M22x1.5 thread.
The nominal 450 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable range of 410-450 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock.
