The LR-RT-240 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 high pressure from the auxiliary gases.

The product features a precision-machined thread, which allows for easy installation and removal of the ceramic during routine maintenance and ensures a durable connection. The LR-RT-240 nut is a reliable, durable replacement, fully compatible with popular Raytools BT240 series Fiber cutting heads used in machines from manufacturers such as Gweike, Bodor, Senfeng, HSG, and many others.
