Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm 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 JSIJ40X450-10S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is more compact than a same-bore ISO 15552 unit. The hard-anodized aluminum barrel keeps the build short, while the G1/4 port supplies air to the double-acting single rod. An external adjuster lets you trim the extend stroke by up to 10 mm on site, meaning the 450 mm nominal length serves as the maximum and the retract end stays fixed.
The built-in magnet (-S) supports CMSE/DMSE sensors in the side grooves for precise position detection. With a safe working load around 377 N, it handles roughly 32 kg lifted vertically. Remember that the adjustable stop sets the end position but does not lock the load; use an external rod lock or pilot-operated check valve if you need to hold a load against air loss.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-10S Is Used
Conveyor Diverter Fine-Tuning
Adjust the 10 mm extend window on site to perfectly align a diverter gate without remounting the entire cylinder.
Packaging Pusher Adjustment
Trim the extend stroke to accommodate varying carton sizes on the fly while maintaining consistent end positions.
Sortation Arm Positioning
Use the magnetic sensors and adjustable stop to set precise sortation arm movements for different package widths.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-10S the Right Cylinder?
This 40 mm bore sits between the lighter 32 mm (402 N push) and the stronger 50 mm (982 N push) at 0.5 MPa. The 10 mm extend-shortening window is ideal for fine-tuning end positions on site or sharing a spare across slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet allows CMSE/DMSE switches. Because the 450 mm stroke is long, always use external guides to prevent rod bending and 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 JSIJ40X450-10S FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical maximum force is 128 kgf at 1.0 MPa. The cylinder features a G1/4 port and a 16 mm rod.
The 450 mm nominal stroke is the maximum length. The external adjuster lets you shorten the extend stroke by up to 10 mm on site, giving a usable range of 440 to 450 mm. The retract end remains fixed, and this stop only sets position rather than holding the load.
