Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X200-20
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X200-20 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 200mm 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 JSIJ80X200-20
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. Its hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port feeds the 25 mm piston rod, yielding a safe working load of about 1508 N, 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 180-200 mm while the retract end stays fixed. This allows fine-tuning without swapping the cylinder. Note that this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors. The adjustable cushion only decelerates the load; use an external rod lock or pilot-operated check valve to hold a load on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X200-20 Is Used
Press Stroke Tuning
Dial in the exact 180-200 mm extend contact point on a light assembly press without machining new spacers.
Divert Arm Adjustment
Fine-tune the extend reach of a sorting divertor on-site to accommodate different package widths.
Pallet Stop Positioning
Set a precise stop distance for varying pallet sizes using the 20 mm external adjuster window.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X200-20 the Right Cylinder?
When sizing, the neighbouring 63 mm bore offers 1559 N push at 0.5 MPa, while the 100 mm bore jumps to 3927 N, so this 80 mm unit hits a strong middle ground. The adjustable stroke is ideal for sharing a spare across 180-200 mm stroke variants or finalizing a machine stop position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a non-magnet SKU, position sensing is unavailable unless you switch to an -S version. For a 200 mm stroke, ensure adequate side-load guidance to prevent rod bearing wear.
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 JSIJ80X200-20 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. It uses a G3/8 port and a 25 mm rod.
The nominal 200 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 20 mm on-site, yielding a usable range of 180-200 mm. The retract end is fixed, and this stop sets position only, not a load lock.
