Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-30S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-30S 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 JSIJ50X300-30S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder keeps your envelope tight because it is shorter and more compact than a same-bore ISO 15552 unit. The hard-anodized aluminium barrel uses no tie rods, and the G1/4 air port matches the bore standard.
The external stop screw lets you trim the extend stroke on-site from the 300 mm maximum down to 270 mm, giving you a 30 mm adjustment window to fine-tune the end position without swapping the cylinder. Because the -S suffix includes a piston magnet, you can drop CMSE or DMSE reed and electronic switches straight into the side grooves. Factoring in a safety margin, this actuator handles about 589 N of real work, which translates to lifting roughly 50 kg vertically.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-30S Is Used
Divert Gate Tuning
Dial in the exact 270 to 300 mm extend reach of a sorting diverter on-site to match varying package sizes without machining new mounts.
Lift Stop Adjustment
Fine-tune the upper lift stop position of a 50 kg vertical elevator platform by up to 30 mm to accommodate different product heights.
Clamp Positioning
Adjust the extend clamping depth on a machining fixture to hold various part thicknesses, using the built-in magnet for end confirmation.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-30S the Right Cylinder?
For sizing, the neighbouring 40 mm bore gives 628 N of push at 0.5 MPa, while the 63 mm bore steps up to 1559 N, so this 50 mm bore sits comfortably in the middle for medium-duty tasks. The 30 mm adjustable window is ideal when you need to share one spare cylinder across several slightly different stroke variants or dial in a final end position on the machine. You can mount it using the FA, LB, TC, TCM1, or TCM2 brackets. Because the stroke is 300 mm, always use an external guide rail to prevent rod bending and side-load damage. The -S magnet supports CMSE and DMSE sensors for position confirmation.
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 JSIJ50X300-30S FAQ
This 50 mm bore cylinder uses a G1/4 air port and a 20 mm piston rod. It generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push and 1154 N pull at 0.7 MPa, and a theoretical maximum of 200 kgf at 1.0 MPa.
The nominal 300 mm stroke is the maximum length. The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 270 to 300 mm. The retract end remains fixed, and this stop only sets the end position rather than holding the load.
