Collection: BOCHU BOCI Ceramic Locking Rings

BOCHU BOCI Ceramic Locking Rings covers the current standard retaining-ring family with M8×0.75 and M11×0.75 configurations, exact part numbers and listed BLT models. Confirm the thread, ring configuration, part number and head model before ordering. M8×0.75 and M11×0.75 are distinct; similar appearance does not establish interchangeability. Water-cooled locking-ring products remain separate components in the cooling umbrella. See Water-cooling Components & Assemblies for that functional family.

Available Ceramic Locking Ring Threads

BOCHU BOCI ceramic locking rings connect and secure ceramic and nozzle-related components in compatible BLT laser cutting heads. Available options include different thread specifications such as M8 × 0.75 and M11 × 0.75, together with model-specific BOCHU part numbers and ring configurations.

How to Select the Correct Locking Rings

Confirm the thread size, ring shape, original part number and compatible cutting-head model before ordering. An M8 ring cannot replace an M11 ring even when the outer appearance is similar. Send a photo of the existing ring, thread and packaging label if the specification is not clearly marked.
