RNC Coated BMG Clone Components Kit by Runice

Runice BMG-style internals kit with RNC-coated drive gears. This is the higher-wear version of the BMG clone component set: a pile of the mechanical parts used to build or refresh a BMG-style dual-drive extruder, with nano-coated steel drive gears aimed at abrasive filament use.

Why use the RNC-coated version?

• The RNC/nano-coated gears are the durability upgrade over the standard silver gear set when you run abrasive materials such as carbon-filled or glass-filled filament.
• BMG-style internals are used across a lot of Voron-era extruder builds, including Afterburner and Mini Afterburner style setups.
• This is useful when you already have the printed/CNC extruder housing and need the internal gear, shaft, bearing, and tension hardware instead of a complete assembled extruder.

Specifications

• Brand: Runice.
• Extruder style: BMG / Bondtech-style clone internals for 1.75mm filament builds.
• Gear upgrade: RNC/nano-coated drive gears for improved wear resistance with abrasive filament.
• Visible kit contents: BMG-style drive gears, 50T reduction gear, shafts, bearings, needle bearings, idler thumb screw with spring, nuts, washer, and orange collet clips.

Fitment and pairing

• Use this for BMG-style extruder builds and rebuilds where the printed or machined housing is supplied separately.
• For a lower-cost standard spare, see the BMG Clone Components Kit.
• For individual spares, pair with BMG Clone Extruder Gears, BMG Style Needle Bearings, or the Extruder Thumb Screw.

What it is not

• Not a complete assembled extruder, hotend, motor, or toolhead.
• Not a genuine Bondtech BMG internals set; this is a Runice BMG-style clone component kit.
• Check your extruder design before ordering: this is for builds that call for BMG-style internal hardware.
