Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X150-20S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X150-20S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 150mm 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 JSIJ80X150-20S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings compact power to pneumatic setups. The extruded hard-anodized aluminium barrel leaves out external rods, making the body shorter and more compact than a same-bore ISO 15552 unit. A built-in magnet (-S) allows CMSE or DMSE switches to clip directly into the side grooves for position sensing.
The -20 code means an external stop screw lets you shorten the extend stroke on-site by up to 20 mm, giving a usable forward travel of 130 to 150 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. It handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically. Air feeds through a G3/8 port, and adjustable cushions decelerate the load at both ends.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X150-20S Is Used
Press Stroke Tuning
Dial in the exact 130 to 150 mm extend reach on a light assembly press without machining new hard stops.
Diverters & Stops
Actuate lane diverters where the exact extended stop position needs slight field adjustment to match product widths.
Pallet Lifters
Lift roughly 128 kg loads vertically, using the adjustable forward stroke to set precise stacking heights.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X150-20S the Right Cylinder?
When sizing this 80 mm bore, stepping down to a 63 mm bore yields 1559 N push at 0.5 MPa, whereas moving up to a 100 mm bore provides 3927 N. This model sits in the heavy-duty range, ideal when a 63 mm unit lacks thrust. The 20 mm adjustable window is perfect for sharing one spare cylinder across several stroke variants or dialing in a final end position on the machine. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. The -S magnet supports CMSE/DMSE sensors. For any stroke at or over 300 mm, always guide the load to prevent side-load damage to the rod seals.
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 JSIJ80X150-20S 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 stroke is 150 mm, which is the maximum forward travel. An external stop screw lets you shorten the extend stroke on-site by up to 20 mm, giving a usable range of 130 to 150 mm. The retract end is fixed, and this stop sets the end position rather than locking the load.
