Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 900mm 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 JSIJ50X900-100S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for long-reach tasks that need precise end-position tuning. The hard-anodized aluminum extruded barrel keeps the body shorter and more compact than a same-bore ISO 15552 unit. It handles about 589 N of real work safely, which means you can lift roughly 50 kg vertically with a 2:1 margin.
The external stop screw lets you shorten the extend stroke on site by up to 100 mm, giving a usable range of 800 to 900 mm while the retract end stays fixed. A built-in magnet (-S) supports CMSE/DMSE sensors in the side grooves for position detection. Air connects via a G1/4 port, and adjustable cushions decelerate the piston at both ends.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-100S Is Used
Extended Transfer Push-Off
Pushes pallets off a long conveyor line, using the 100 mm adjuster to dial in the exact push distance for varying pallet depths without repositioning the cylinder.
High-Bay Divert Gate
Actuates a diverting gate at the end of a 900 mm stroke, allowing on-site stroke shortening to accommodate new lane widths while maintaining smooth deceleration.
Vertical Material Lift
Raises a 50 kg load platform vertically, relying on the compact JIS profile to save headroom and the built-in magnet to confirm the raised position.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-100S the Right Cylinder?
When sizing, the neighboring 40 mm bore yields 628 N push at 0.5 MPa, while stepping up to 63 mm provides 1559 N, so this 50 mm bore sits perfectly in the middle for medium loads. The 100 mm adjustable window is ideal when you need to fine-tune the extend endpoint without swapping cylinders or need a shared spare across slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the 900 mm stroke is quite long, always use an external guide rail to prevent rod bending and side-load damage.
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 JSIJ50X900-100S 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.
An external stop screw lets you shorten the extend stroke on site by up to 100 mm, giving a usable extend range of 800 to 900 mm. The nominal 900 mm stroke is the maximum, and the retract end is fixed. This stop sets the end position and does not lock the load.
