Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-30S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 200mm 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 JSIJ50X200-30S
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 aluminium barrel keeps the body shorter and more compact than a same-bore ISO 15552 unit. A built-in piston magnet works directly with CMSE/DMSE switches in the side grooves.
The external adjuster lets you shorten the extend stroke by up to 30 mm on site, giving a usable 170-200 mm range while the retract end stays fixed. This means you can fine-tune the end position without swapping the cylinder. It handles a safe working load of about 589 N, lifting roughly 50 kg vertically with a 2:1 margin. Pneumatic connections use a G1/4 port.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-30S Is Used
Clamp Position Tuning
Dial in the exact 170-200 mm extend reach on a machining fixture so the clamp seats perfectly without re-engineering the mount.
Variable Stroke Diverters
Adjust the extend stop on a conveyor diverter gate by up to 30 mm to handle different package widths on the same line.
Vertical Lift Stops
Lift a 50 kg payload and fine-tune the upper stop position safely, relying on the adjuster rather than adding mechanical spacers.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-30S the Right Cylinder?
This 50 mm bore sits neatly between the 40 mm (628 N push at 0.5 MPa) and 63 mm (1559 N) sizes, giving you a clear upgrade path if your 40 mm stalls or a 63 mm is too bulky. The 30 mm adjustable window is ideal when you need to share one spare cylinder across several stroke variants or dial in a final end position on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S suffix means the magnet is present for CMSE/DMSE sensors. For any stroke at or over 300 mm, guide the load externally to prevent side-load wear on the rod.
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 JSIJ50X200-30S 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 is 200 kgf at 1.0 MPa. The air port is G1/4.
The nominal 200 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 30 mm on site, giving a usable 170-200 mm range. The retract end is fixed. This stop only sets the end position; it is not a load lock.
