Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X160-20S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X160-20S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 160mm 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 JSIJ80X160-20S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for applications needing on-site end-position tuning. The hard-anodized aluminum extruded barrel makes it shorter and more compact than a same-bore ISO 15552 unit. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin.
The -20 code means an external adjuster can shorten the extend stroke by up to 20 mm on-site, giving a usable range of 140-160 mm while the retract end stays fixed. You can fine-tune the stop without swapping the cylinder. This -S SKU includes a piston magnet for CMSE/DMSE sensors that drop directly into the side grooves. Pneumatic connections use a G3/8 port.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X160-20S Is Used
Press Stroke Tuning
Dial in the exact 140-160 mm extend contact point on-site for light stamping or forming tasks without machining spacers.
Variable Transfer Stops
Adjust the stopper block position on the fly to handle different package sizes on a single sorting line.
Pallet Positioning
Fine-tune the extend end position to align pallets precisely before stretch wrapping, using the built-in magnet for confirmation.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X160-20S the Right Cylinder?
Size this 80 mm bore against the neighboring 63 mm and 100 mm options. At 0.5 MPa it yields 2513 N push and 2268 N pull, sitting comfortably between the 63 mm (1559 N) and 100 mm (3927 N) classes. The adjustable stroke is ideal when you need to share a spare across stroke variants or dial in a precise end position after mounting. JSIJ supports Basic, FA, LB, TC, TCM1, and TCM2 mounts. For any stroke at or over 300 mm, use a guide rail to prevent side-load damage.
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 JSIJ80X160-20S 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 maximum force is 513 kgf at 1.0 MPa. The air port is G3/8.
An external stop screw lets you shorten the extend stroke by up to 20 mm on-site, giving a usable range of 140-160 mm. The nominal 160 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position and is not a load lock.
