Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-50S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 80mm stroke, G1/4 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 JSIJ32~50 Adjustable Cylinder JSIJ50X80-50S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder features a hard-anodized aluminum barrel that is noticeably shorter than a same-bore ISO 15552 unit. The external adjuster allows you to shorten the extend stroke on-site by up to 50 mm, meaning the 80 mm nominal stroke can be fine-tuned down to a 30 mm usable length without swapping the actuator. It handles about 589 N of safe working load, which translates to roughly 50 kg lifted vertically with a 2:1 margin.
Equipped with a built-in piston magnet (-S), the body accepts CMSE/DMSE sensors that drop directly into the side grooves for precise position detection. Air connections use a G1/4 port, and adjustable air cushions at both ends absorb end-of-stroke impact. Remember that the cushion only decelerates the piston; a plain cylinder cannot hold a load on air loss, so fit an external rod lock or pilot-operated check valve if you need strict positioning.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-50S Is Used
Variable Stroke Clamping
Dial in the exact clamping depth on parts of varying heights by using the 50 mm extend window to shorten the 80 mm nominal stroke on the fly.
Adjustable Transfer Pusher
Fine-tune the push-off distance at the end of a line without machining new hard stops, adjusting the extend stroke from 80 mm down to 30 mm as needed.
Compact Sorting Diverter
Fit a shorter JIS profile body into tight conveyor gaps while using the magnet and sensor groove to confirm divert positions.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-50S the Right Cylinder?
This 50 mm bore sits in the middle of the range, offering 982 N push at 0.5 MPa. If your task needs less force, step down to the 40 mm bore (628 N push); for heavier duties, step up to the 63 mm bore (1559 N push). The 50 mm adjustable window is ideal when you need to share one spare cylinder across several stroke variants or dial in an exact end position on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is an -S model, it arrives ready for CMSE/DMSE reed or electronic switches. For any application with a stroke of 300 mm or more, always guide the load to prevent side-load damage to the rod.
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 JSIJ32~50 Adjustable Cylinder JSIJ50X80-50S FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it provides 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. The air port is G1/4.
The 80 mm stroke is the maximum nominal length. The external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 30 to 80 mm. The retract end remains fixed, and this stop sets the end position rather than locking the load.
