Bambu Induction Hotend Rack Belt Assembly — H2C (FAC188)

Official Replacement Part • Precision Hotend Positioning • Genuine Bambu Lab Component

Overview

The Bambu Induction Hotend Rack Belt Assembly (FAC188) is the official replacement belt assembly for the Bambu Lab H2C induction hotend system. As a core component of the Vortek automatic hotend exchange mechanism, it transfers rotational motion from the rack motor into precise vertical movement, allowing the induction hotend to be accurately lifted, positioned, docked, and stored during automatic tool changes.

If the belt becomes worn, stretched, or damaged, replacing it restores accurate hotend positioning and helps maintain reliable automatic hotend exchanges.
