Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-40S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-40S 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 JSIJ50X80-40S
Generating 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for applications that demand exact end-position tuning. The external stop screw provides a 40 mm adjustment window, allowing you to shorten the 80 mm extend stroke on-site down to a 40 mm usable length without swapping the actuator. The retract end remains fixed. Because the nominal stroke is the maximum, you can fine-tune the extension precisely where the machine requires it.
This extruded hard-anodized aluminum body is noticeably shorter than a same-bore ISO 15552 cylinder, saving valuable machine space. It handles about 589 N of real work safely, which translates to lifting roughly 50 kg vertically with a 2:1 margin. The built-in piston magnet (-S) supports CMSE/DMSE sensors in the side grooves for position confirmation. Air connects via the G1/4 port, and adjustable air cushions at both ends absorb kinetic energy at the stroke limits.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-40S Is Used
Adjustable Clamping Stop
Dial in the 40 mm extend window on-site to set a precise 55 mm clamping distance for varying part widths without changing the cylinder.
Variable Transfer Diverter
Fine-tune the actuator stroke from the full 80 mm down to 40 mm to deflect packages of different sizes accurately on a packaging line.
Vertical Lift Positioning
Lift loads up to 50 kg and use the external stop screw to set the exact raise height, preventing over-travel in tight vertical spaces.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X80-40S the Right Cylinder?
When sizing this actuator, compare it against the neighboring 40 mm bore (628 N push at 0.5 MPa) and the 63 mm bore (1559 N push at 0.5 MPa) to ensure your force margin is correct. The 40 mm adjustable window is ideal when you need to share a single spare cylinder across multiple stroke variants or dial in a precise end position on-site. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The integrated magnet allows you to fit CMSE/DMSE reed or electronic switches directly into the profile groove. For any stroke length at or above 300 mm, always use a guide rail to prevent side-load damage to the piston 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 JSIJ50X80-40S 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 size is G1/4.
The nominal 80 mm stroke is the maximum extension. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 40 to 80 mm. The retract end is fixed. This stop sets the end position but does not lock the load.
