Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-50S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 50mm 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 JSIJ80X50-50S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder features an external adjuster that shortens the extend stroke on site by up to 50 mm. The nominal 50 mm stroke is the maximum, yielding a usable extend range of 0-50 mm, while the retract end stays fixed. It handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin.
Built with an extruded hard-anodized aluminum barrel, the unit is shorter and more compact than a same-bore ISO 15552 cylinder. The -S suffix adds a piston magnet for CMSE/DMSE sensors that drop directly into the side grooves. Pneumatic connections use a G3/8 port, and adjustable air cushions of 29 mm at each end absorb end-of-stroke impact. A plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a load.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-50S Is Used
Press Fit Tuning
Dial in the exact 0-50 mm extend contact point for seating bearings without remounting the entire actuator.
Variable Transfer Stop
Adjust the extend stop on site to handle mixed carton widths on a single packing line.
Pallet Positioning
Lift loads up to 128 kg vertically and fine-tune the raise height to clear varying pallet heights.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X50-50S the Right Cylinder?
Size this 80 mm bore against the 63 mm class, which provides 1559 N push at 0.5 MPa, or step up to the 100 mm class for 3927 N. The JSIJ series supports Basic, FA, LB, TC, TCM1 and TCM2 mounts. The -50 mm adjustable window lets you fine-tune the extend end position without swapping cylinders, perfect for sharing a spare across stroke variants. The -S magnet enables CMSE/DMSE switches for position feedback. For any stroke at or above 300 mm, always use a guide rail 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 JSIJ80X50-50S 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 max is 513 kgf at 1.0 MPa. The air port is G3/8.
The external adjuster lets you shorten the extend stroke on site by up to 50 mm. The nominal 50 mm stroke is the maximum, giving a usable extend range of 0-50 mm, while the retract end remains fixed.
