Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-100S 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 JSIJ50X300-100S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to demanding automation. A built-in piston magnet (-S) supports CMSE/DMSE sensors in the side grooves, while the hard-anodized aluminum barrel keeps the total length shorter than a same-bore ISO 15552 unit. The G1/4 port feeds a double-acting single-rod design rated for 30-800 mm/s.
The external -100 mm adjuster lets you shorten the extend stroke from the 300 mm maximum down to 200 mm without changing the hardware, leaving the retract end fixed. This on-site tuning handles about 589 N of real work safely, which is roughly 50 kg lifted vertically with a 2:1 margin. Remember that the air cushion only decelerates the piston near the ends; it does not lock the load, so use an external rod lock or pilot-operated check valve for holding.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-100S Is Used
Adjustable Stopper Arms
Fine-tune the 200-300 mm extend reach on-site to catch workpieces of varying widths without swapping the cylinder.
Transfer Pusher Setup
Dial in the exact push-off distance for diverter gates, using the 100 mm window to compensate for belt drift.
Pallet Positioning
Set precise end stops for pallet alignment pins, adjusting the extend stroke quickly during line changeovers.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-100S the Right Cylinder?
When sizing, step down to a 40 mm bore for lighter duties (628 N push at 0.5 MPa) or up to a 63 mm bore for heavier loads (1559 N push at 0.5 MPa). The 100 mm adjustable window is ideal for sharing a spare across stroke variants or fine-tuning the end position during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 300 mm, always use an external guide rail to prevent rod bending and side-load damage. The -S magnet allows drop-in CMSE/DMSE switches for position sensing.
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 JSIJ50X300-100S FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it provides 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. The air port is G1/4, the rod is 20 mm with an M18x1.5 thread, and it has 20.5 mm adjustable air cushions at both ends.
The nominal 300 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 100 mm on-site, giving a usable extend range of 200-300 mm. The retract end remains fixed. This mechanism sets the end position and does not lock the load.
