Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X600-50S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X600-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 600mm 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 JSIJ80X600-50S
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 600 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. An integrated piston magnet prepares the unit for CMSE or DMSE switches that mount directly into the side barrel grooves. This hard-anodized aluminum body is more compact than a same-bore ISO 15552 unit, and its G3/8 port handles the required airflow.
The 50 mm adjustment window yields a usable extend range of 550 to 600 mm, while the retract end stays fixed. In practice it handles about 1508 N of real work safely, which translates to roughly 128 kg lifted vertically with a 2:1 margin. Note that a standard cylinder drifts on air loss; the adjustable air cushions only decelerate the piston near the ends, 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 JSIJ80X600-50S Is Used
Transfer Line Diverter
Fine-tune the 550 to 600 mm extend position on-site to match varying pallet widths without changing the cylinder mounting.
Lowering Press Head
Safely lower a 128 kg platen vertically using the 80 mm bore, relying on the adjustable cushions for smooth end-of-stroke deceleration.
Long-Reach Material Gate
Actuate a 600 mm routing gate in a packaging line, using the external adjuster to shorten the stroke by 50 mm when aisle space changes.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X600-50S the Right Cylinder?
When sizing this 80 mm bore actuator, the neighbouring 63 mm option yields 1559 N push at 0.5 MPa, whereas stepping up to the 100 mm bore provides 3927 N, giving you clear boundaries for your force requirements. The 50 mm on-site extend-shortening window is ideal for dialing in final end positions during commissioning or standardizing a shared spare across slightly different stroke variants. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. The -S suffix confirms the built-in magnet for CMSE/DMSE sensors. Because the 600 mm stroke is long, always support the load with external guides to prevent rod bending and excessive side loading.
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 JSIJ80X600-50S 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, and the air port size is G3/8.
The external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 550 to 600 mm. The nominal 600 mm stroke is the maximum travel, and the retract end remains fixed.
