Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 450mm 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 JSIJ50X450-10S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder saves machine length by being shorter than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel uses no tie rods, keeping the build light. It handles a safe working load of about 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 margin.
The JSIJ50X450-10S features an external stop screw that lets you trim the extend stroke by up to 10 mm on site, giving a usable range of 440-450 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. The -S suffix means a built-in magnet for CMSE/DMSE sensors in the side grooves. Air connects via a G1/4 port, and adjustable cushions decelerate the load at both ends.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-10S Is Used
Conveyor Diverter
Fine-tune the 450 mm extend reach by up to 10 mm to perfectly align a diverter gate without machining new mounts.
Vertical Lift Stop
Lifts around 50 kg using the 982 N thrust, with the adjustable stop screw setting the exact upper travel limit.
Press Clamping
Dial in the clamping end-position on-site to compensate for material thickness variance across production runs.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-10S the Right Cylinder?
Size this 50 mm bore against its neighbours: step down to a 40 mm for lighter loads (628 N push at 0.5 MPa) or up to a 63 mm (1559 N) if you need more thrust. The 10 mm adjustable window is ideal for sharing one spare across slightly different stroke variants or finalizing end positions during commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 450 mm stroke is long, always use an external guide to prevent rod bending and side-load damage. The -S magnet supports CMSE/DMSE switches for position sensing.
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 JSIJ50X450-10S FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 port and a 20 mm rod.
The nominal 450 mm stroke is the maximum. An external adjuster lets you shorten the extend stroke by up to 10 mm on site, giving a usable range of 440-450 mm. The retract end is fixed. This stop sets position only; it does not lock the load.
