Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X50-40S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X50-40S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 50mm stroke, G1/8 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 JSIJ32~50 Adjustable Cylinder JSIJ32X50-40S
The nominal 50 mm stroke acts as the maximum travel, while the -40 code means you can fine-tune the end position down to a 10 mm usable extend window without swapping the actuator. This on-site flexibility makes it ideal for dialing in precise stops. The hard-anodized aluminum barrel keeps the total length shorter than a same-bore ISO 15552 unit, saving valuable machine space.
The integrated -S magnet allows CMSE or DMSE sensors to drop directly into the side grooves for position detection. Air connects via a G1/8 port, and adjustable cushions at both ends manage end-of-stroke deceleration. Remember that the cushion only slows the piston; an external rod lock or pilot-operated check valve is required to hold a load securely against air loss.

JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X50-40S Is Used
Probe Positioning
Dial in the exact extend contact point for a testing probe on an assembly line, using the 40 mm adjustment window to set the stroke anywhere from 10 to 50 mm.
Small Part Ejection
Tune the ejection distance of small plastic parts from a mold to accommodate varying product sizes without physically replacing the cylinder.
Sorting Diverter
Adjust the pusher extension on a conveyor diverter to safely deflect packages of different depths while relying on the compact JIS profile to fit tight transfer gaps.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X50-40S the Right Cylinder?
Conversely, if your payload is extremely light, a smaller actuator might suffice, though 32 mm is often the practical floor for standard pneumatic setups. The adjustable stroke shines when you need to share a single spare cylinder across multiple stroke variants or fine-tune a final end position on the factory floor. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix ensures you have a piston magnet ready for CMSE/DMSE switches. Because the stroke here is under 300 mm, standard side-load risks are minimal, but always guide the load properly to prevent rod binding.
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 JSIJ32X50-40S FAQ
At 0.7 MPa the push is 563 N and pull is 483 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It features a 12 mm rod, a G1/8 port, an M10x1.25 rod thread, and 20 mm adjustable cushions at both ends.
The -40 code indicates a 40 mm external adjustment window. The nominal 50 mm stroke is the maximum extend travel, but turning the external stop screw lets you shorten the extend stroke down to 10 mm on site. The retract end position remains fixed, and this mechanism sets the end stop rather than locking the load.
