The LR-RT-111 precision locking nut for the ceramic ring (locking ring / clamping nut) is a key assembly component used in the cutting systems of industrial CNC laser cutters. The main function of this component is to securely lock and mount the ceramic insulator onto the laser head. This ensures stable positioning of the cutting nozzle and eliminates the risk of play that could interfere with the operation of the height sensor under the influence of high pressure from auxiliary gases (nitrogen or oxygen).

The product features a precision-machined thread, allowing for easy, manual installation and removal of the ceramic insulator during routine maintenance. The LR-RT-111 nut is a reliable, durable replacement, fully compatible with popular Raytools Fiber cutting heads (including the BM111, BM114, BM114S, BM115) as well as WSX heads used in machines from manufacturers such as Gweike, Bodor, Senfeng, HSG, and many others.
