Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X200-20S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X200-20S 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 JSIJ80X200-20S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder is built for tasks that demand exact end-position control on the fly. The hard-anodized aluminum barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. A built-in piston magnet (-S) allows CMSE or DMSE switches to drop directly into the side grooves for position sensing.
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 without swapping the cylinder. It handles about 1508 N of real work safely, translating to roughly 128 kg lifted vertically. Air connects via a G3/8 port, and adjustable air cushions at both ends absorb impact. Note that a plain cylinder drifts on air loss; use an external rod lock for held loads.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X200-20S Is Used
Press Fit Tuning
Dial in the exact 180-200 mm extend position on-site to seat bearings without bottoming out the tooling.
Variable Stopper Arm
Adjust the extend stop distance by up to 20 mm to handle different pallet widths on a shared line.
Clamp Depth Control
Fine-tune the clamping reach against varying carton thicknesses while maintaining full retract clearance.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X200-20S 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 unit sits perfectly in the middle for medium-heavy automation. The adjustable stroke is ideal for fine-tuning a pressing or clamping end position during commissioning, and it lets you standardize on one 200 mm spare for slightly shorter operations. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix equips the cylinder for CMSE/DMSE sensors. For any stroke over 300 mm, always guide the load 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 JSIJ80X200-20S 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 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 180-200 mm range. The retract end remains fixed, and this stop is for positioning only, not load holding.
