LGX Primary Double Gear - Bondtech

The LGX Primary Double Gear is a critical component of the dual-gear drive mechanism used in Bondtech's LGX extruders, ensuring consistent and reliable filament feeding. This advanced design employs interlocking gears to firmly grip the filament, enhancing torque and eliminating slippage. The result is smoother extrusion performance, particularly beneficial when working with challenging materials such as flexible or abrasive filaments.

Manufactured as an official spare part for LGX Large Gears extruders, this primary double gear is crafted from PBT GF20, a high-performance technical polymer. Compared to conventional materials like POM, PBT GF20 offers superior mechanical strength and resistance to higher working temperatures. These characteristics ensure the gear’s longevity and reliability under demanding 3D printing conditions, making it a durable choice for professional and hobbyist users alike.
