    Key Features
    ● Higher Strength and Wear Resistance：The medium-carbon steel section bears the main torque and impact loads, offering excellent wear resistance, long service life, and suitability for heat treatment. Compared with all-plastic gears, this design provides significantly improved resistance to tooth breakage.
    ● Lower Noise and Smoother Operation：The plastic component features good self-lubricating properties and effectively absorbs vibration during meshing, reducing noise. Compared with all-metal gears, this hybrid structure operates more quietly and smoothly.
    ● Balanced Cost and Performance：This gear design is more cost-effective than fully steel gears, while offering higher reliability and durability than all-plastic gear solutions. Lower Lubrication Requirements：Plastic gears can operate under low-lubrication or even lubrication-free conditions, making them suitable for applications with limited maintenance.
