Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X250-30S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X250-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 250mm 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 JSIJ80X250-30S
Generating 2513 N of push force at 0.5 MPa, this 80 mm bore unit brings on-site extend-stroke flexibility to heavy pneumatic automation. The hard-anodized aluminum profile barrel makes the overall body more compact and shorter than a same-bore ISO 15552 cylinder. A G3/8 port feeds the 25 mm rod, driving a 30-800 mm/s speed range.
The external stop screw lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 220-250 mm range while keeping the retract end fixed. This means you can fine-tune the end position without swapping the cylinder. The -S suffix adds a piston magnet for CMSE/DMSE sensors. It handles about 1508 N of real work safely, roughly 128 kg lifted vertically with a 2:1 margin.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X250-30S Is Used
Press Stroke Tuning
Dial in the exact 220-250 mm extend reach on a light assembly press without machining spacers, using the external adjuster to set the precise contact point.
Divertor Arm Positioning
Fine-tune the extend stop on a sorting line divertor to accommodate different package widths on-site, relying on the 2513 N push force to move loads reliably.
Vertical Lift Stops
Adjust the extend endpoint on a materials lift to hit varying shelf heights precisely, safely handling around 1508 N of working load with the built-in magnet for confirmation.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X250-30S the Right Cylinder?
When sizing, the 63 mm bore offers 1559 N push at 0.5 MPa, while the 100 mm bore jumps to 3927 N, so this 80 mm bore sits perfectly in the middle for medium-heavy tasks. The -30 mm adjustable window is ideal for sharing one spare across slight stroke variants or dialing in final end positions on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 250 mm, ensure adequate side-load guidance to prevent rod bearing wear. The -S magnet supports CMSE/DMSE switches for position feedback.
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 JSIJ80X250-30S FAQ
At 0.5 MPa it delivers 2513 N push and 2268 N pull. At 0.7 MPa it provides 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa. This 80 mm bore cylinder uses a G3/8 air port and a 25 mm piston rod.
The nominal 250 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 30 mm on-site, giving a usable range of 220-250 mm. The retract end remains fixed. This mechanism only sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.
