RNC Coated BMG Clone Components Kit by Runice
Couldn't load pickup availability
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.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
