Attention laser cutting pros! If you need a replacement ceramic nozzle holder for your fiber laser cutting head, this is a high-quality option. It's made from durable ceramic with a Mohs hardness of 9, so it can withstand the intense environment inside your laser head. You have two size choices: Type A with an outside diameter of 28mm (24.5mm inner) and a thickness of 12mm, or Type B which is 32mm OD (28.5mm inner) and also 12mm thick. These are designed to be compatible with popular laser head brands like Precitec WSX, Precitec HSG, Raytools, Bodor, and similar models. It's a crucial protective component that helps ensure stable signal transmission and high sensitivity during cutting. The high-quality alloy construction prevents bursting, and the welding is solid so it won't fall apart. Whether you're doing maintenance or repairing a damaged head, this ceramic holder is built for performance and longevity. Always double-check your machine's model and the exact part dimensions before ordering to make sure it's the right fit for your setup. Keep your laser running sharp!
