Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-20
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-20 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 800mm 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 JSIJ50X800-20
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder cuts a shorter footprint than a same-bore ISO 15552 unit while packing an 800 mm extend. The hard-anodized aluminium barrel skips external rods for a clean exterior. A G1/4 port feeds the double-acting single-rod piston, yielding a theoretical maximum of 200 kgf at 1.0 MPa.
The external stop screw provides a 20 mm on-site adjuster window, letting you fine-tune the extend end position down to 780 mm without swapping the actuator. In practical terms it handles a safe working load of roughly 589 N, which translates to lifting about 50 kg vertically with a 2:1 margin. Note this plain SKU lacks a magnet and cannot take CMSE or DMSE sensors.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-20 Is Used
Long-Reach Diverting
Pushes cartons across a wide belt at 800 mm, with the 20 mm window trimming the stroke to match varying lane widths.
High-Bay Extraction
Extracts totes from deep shelving racks, using the adjustable stop to account for slightly recessed bin positions.
Vertical Press Down
Lowers a 50 kg tooling head over a long drop, fine-tuning the bottom position without remounting the actuator.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-20 the Right Cylinder?
Size this 50 mm bore against its neighbours: step down to a 40 mm for lighter 628 N tasks, or up to a 63 mm when you need 1559 N at 0.5 MPa. The 20 mm extend-shortening window is ideal for sharing one spare across slightly different stroke machines or dialling in final end positions on-site. Mount via FA, LB, TC, TCM1 or TCM2 brackets. Because the stroke is 800 mm, always support the load with an external guide to prevent rod bending and side-load wear.
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 JSIJ50X800-20 FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa push is 1374 N and pull is 1154 N. The theoretical maximum is 200 kgf at 1.0 MPa. It uses a G1/4 air port.
The nominal 800 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 20 mm on-site, giving a usable range of 780-800 mm. The retract end remains fixed, and this stop only sets position; it does not lock the load.
