Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-30 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 50mm 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 JSIJ50X50-30
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to mid-range pneumatic setups. The hard-anodized aluminum barrel keeps the build 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 adjuster lets you shorten the extend stroke by up to 30 mm on site, dropping the usable extension from the 50 mm maximum down to 20 mm without changing the cylinder itself. The retract end remains fixed, and the G1/4 port handles the air supply. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-30 Is Used
Clamp Stroke Tuning
Dial in the exact 20 to 50 mm clamp extension on a machining fixture without swapping cylinders, absorbing part tolerance variations directly at the machine.
Transfer Gate Stop
Set the precise pusher distance on a conveyor diverter gate, adjusting the 30 mm window on-site to handle different package sizes on the fly.
Press Pin Insertion
Control the downward extend stroke for pressing pins, using the external stop to limit travel and prevent over-travel on delicate assemblies.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-30 the Right Cylinder?
When sizing this unit, the 63 mm bore neighbor steps up to 1559 N push at 0.5 MPa, while the 40 mm bore drops to 628 N, so the 50 mm bore sits right in the middle for moderate loads. The 30 mm adjustable window is ideal for sharing one spare across slight stroke variants or fine-tuning an end position after mechanical mounting. You can fit it using FA, LB, TC, TCM1, or TCM2 brackets. Because this is a non-magnet SKU, switch sensing is impossible without moving to an -S version. For any stroke at or over 300 mm, always guide the load to prevent rod 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 JSIJ50X50-30 FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it delivers 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa, and the air port size is G1/4.
The nominal 50 mm stroke is the maximum extension. The external adjuster lets you shorten the extend stroke by up to 30 mm on site, giving a usable extend range of 20 to 50 mm. The retract end is fixed, and this stop only sets position—it does not hold the load if air pressure drops.
