Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-50S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-50S 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 JSIJ50X900-50S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for long-reach tasks. The hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit. It handles about 589 N of real work safely, which means lifting roughly 50 kg vertically with a 2:1 margin.
A built-in magnet (-S) allows CMSE or DMSE switches to drop directly into the side sensor grooves. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 850-900 mm without swapping the cylinder. Air connects via a G1/4 port, and the retract end remains fixed.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-50S Is Used
Long-Reach Diverting
Pushes items across a wide conveyor belt, using the 50 mm adjuster to fine-tune the exact push-off distance on-site without changing the cylinder mount.
High-Bay Shuttle
Acts as a horizontal shuttle actuator in storage retrieval systems where the 900 mm reach and compact JIS body length free up valuable machine space.
Vertical Lowering
Lowers light fixtures or product trays; the adjustable stop screw sets the precise resting height, while the magnet tracks the full travel.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-50S the Right Cylinder?
When sizing, the 40 mm bore gives 628 N push at 0.5 MPa, while the 63 mm bore jumps to 1559 N if you need more force. The 50 mm bore is the middle ground. The 50 mm adjustable window is perfect for fine-tuning the extended end position on-site or sharing one spare across multiple stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 900 mm, always use external guides to prevent rod bending and manage side loads.
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 JSIJ50X900-50S 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. The air port size is G1/4.
The nominal 900 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 850-900 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
