Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 300mm 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 JSIJ50X300-10S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore adjustable-stroke actuator brings on-site flexibility to demanding pneumatic setups. The hard-anodized aluminum profile barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder, while the G1/4 port keeps airflow balanced for a 30-800 mm/s speed range.
An external stop screw lets you trim the extend stroke by up to 10 mm on site, giving a usable range of 290-300 mm without swapping the cylinder. The built-in magnet (-S) supports CMSE/DMSE sensors in the side grooves for precise end-position detection. In practice it handles about 589 N of real work, which is roughly 50 kg lifted vertically with a 2:1 safety margin.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-10S Is Used
Conveyor Diverter Fine-Tuning
Adjust the 10 mm extend window on site to perfectly align a diverter gate without remounting the entire actuator.
Variable Depth Carton Sealing
Dial in the exact 290-300 mm push stroke needed for different box sizes on a dynamic packaging line.
Vertical Lift Positioning
Safely lift 50 kg loads vertically using the 982 N push force, tweaking the end stop to match shelf heights.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-10S the Right Cylinder?
This 50 mm bore sits between the 40 mm (628 N push at 0.5 MPa) and the 63 mm (1559 N) options, giving you a clear upgrade path if force demands shift. The -10 mm adjuster is ideal when you need to fine-tune the extend end position across multiple stations or want a shared spare for slightly different stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Because the stroke is 300 mm, always use an external guide to prevent rod bending and side loads. The -S magnet is present, ready for CMSE/DMSE switches.
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 JSIJ50X300-10S FAQ
It pushes 982 N and pulls 825 N at 0.5 MPa. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa.
The -10 code means an external adjuster can shorten the extend stroke by up to 10 mm on site. The usable extend range is 290-300 mm, with 300 mm being the maximum. The retract end is fixed, and the stop screw sets the end position rather than locking the load.
