Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-50
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-50 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 JSIJ50X450-50
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS actuator brings on-site flexibility to long-stroke tasks. The hard-anodized aluminum profile barrel keeps the total body shorter 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.
An external stop screw provides a 50 mm adjustment window, letting you fine-tune the extend end position from 400 to 450 mm without swapping the cylinder. The retract end remains fixed. This plain SKU lacks a magnet and cannot take CMSE or DMSE sensors. Air connects via a G1/4 port, and adjustable air cushions of 20.5 mm decelerate the piston at both ends.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-50 Is Used
Transfer Line Diverter
Tunes the extend stroke on-site by up to 50 mm to push varying box sizes onto parallel conveyors without repositioning the whole actuator assembly.
Vertical Press Stop
Uses the external adjuster to set a precise 400 to 450 mm lower end position for a light pressing or seating operation that requires field calibration.
Long-Reach Pallet Stop
Acts as a 450 mm travel gate arm on a palletizing cell, where the 50 mm window allows operators to alter the stopping distance for mixed pallet dimensions.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-50 the Right Cylinder?
When sizing, the 40 mm bore offers 628 N push at 0.5 MPa for lighter jobs, while the 63 mm bore jumps to 1559 N if you need more power. The 50 mm bore hits a solid middle ground at 982 N. The 50 mm adjustable window is ideal for sharing one spare across multiple stroke variants or dialing in a precise end stop on the machine. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 450 mm stroke is long, always support the rod against side-loads with an external guide to prevent bending. Remember that this non-magnetic model cannot host position sensors.
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 JSIJ50X450-50 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 450 mm extend stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 400 to 450 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
