Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 600mm 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 JSIJ50X600-100S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings on-site extend tuning to long-stroke automation. Its external adjuster lets you shorten the forward stroke by up to 100 mm, giving a usable range of 500 to 600 mm while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder. The hard-anodized aluminum barrel uses no tie rods, making the body shorter and more compact than a same-bore ISO 15552 unit.
This -S variant includes a built-in piston magnet for CMSE/DMSE sensors that drop directly into the side grooves. It handles a safe working load of about 589 N, which is roughly 50 kg lifted vertically with a 2:1 margin. Air connects via a G1/4 port, and adjustable cushions decelerate the piston at both ends. Remember that the cushion only slows the load near the stroke end; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-100S Is Used
Transfer Line Diverter
Dial in the exact push distance to deflect parts onto a branch line, using the 100 mm window to compensate for varying product sizes without changing cylinders.
Long-Reach Pallet Stop
Use the 600 mm extension to reach across a wide roller section, fine-tuning the stopping position by up to 100 mm to match different pallet depths.
Adjustable Forming Press
Set the precise 500 to 600 mm extend position for pressing operations, allowing quick on-site adjustments for different material thicknesses.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-100S the Right Cylinder?
Size this 50 mm bore against its neighbors: a 40 mm gives 628 N push at 0.5 MPa, while a 63 mm jumps to 1559 N. Choose the 50 mm when you need roughly 589 N of safe working load. The 100 mm adjuster window is ideal when you need to dial in a precise end position on-site or want a single spare cylinder that covers 500 to 600 mm variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 600 mm, always support the load with an external guide to prevent rod bending and side-load damage. The -S magnet supports CMSE/DMSE switches for position sensing.

- ✓ 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 JSIJ50X600-100S 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. It uses a G1/4 port and a 20 mm rod.
The nominal 600 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 500 to 600 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
