Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X300-75
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X300-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 300mm 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 JSIJ80X300-75
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder saves valuable machine space by being shorter than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel keeps the build light without external rods. It handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin.
The -75 code means an external stop screw lets you shorten the extend stroke on site by up to 75 mm, giving a usable range of 225-300 mm. Nominal 300 mm is the maximum, and the retract end remains fixed. Air connects via a G3/8 port. Note this specific SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X300-75 Is Used
Transfer Push-Off Tuning
Trim the 300 mm extend stroke by up to 75 mm on site to dial in the exact push-off distance for varying pallet sizes without changing the cylinder.
Vertical Lift Stop
Lift roughly 128 kg vertically using the 2513 N thrust, adjusting the end position externally to match varying shelf heights.
Clamp Positioning
Set the precise clamping reach between 225 mm and 300 mm on the fly, accommodating different part widths while keeping the retract fixed.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X300-75 the Right Cylinder?
Size this 80 mm bore against its neighbours: a 63 mm gives 1559 N push at 0.5 MPa, while a 100 mm yields 3927 N. The JSIJ mounting set includes Basic, FA, LB, TC, TCM1, and TCM2. The adjustable window is ideal for sharing one spare across stroke variants or fine-tuning end positions without swapping the cylinder. Because the stroke is 300 mm, use an external guide to prevent rod bending and side loads. For sensing, you must select the -S magnet version for 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 JSIJ80X300-75 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 force is 513 kgf at 1.0 MPa. It uses a G3/8 port, a 25 mm rod, and has 29 mm adjustable air cushions at both ends.
An external stop screw lets you shorten the extend stroke by up to 75 mm on site. The usable extend range is 225-300 mm, with 300 mm being the maximum. The retract end is fixed. This mechanism sets the end position and does not hold the load; use an external rod lock or pilot-operated check valve for load holding.
