Product Features
Precision Grinding: The tooth flanks are finely ground to achieve low surface roughness and tooth profile accuracy up to ISO Grade 4-5, ensuring smooth meshing and minimal backlash.
Deep Carburizing: Made from high-quality low-carbon alloy steel, the gears undergo carburizing and quenching to reach a consistent surface hardness of 58-62 HRC, while the core remains tough.
High Load Capacity: Optimized tooth root fillets eliminate stress concentration, allowing the gears to withstand heavy loads and shock impacts.
4. Strict QC: Every batch is tested using gear testers and hardness testers before shipment to ensure reliability.

FAQ
Q: What is the core advantage of ground spur gears over standard cut gears?
A: The core advantage lies in the perfect combination of precision and hardness. The grinding process significantly improves accuracy, ensuring tighter meshing which reduces noise and vibration. Coupled with a surface hardness of 58-62 HRC, the gears maintain extremely low wear rates under high-speed operations, resulting in higher transmission efficiency and lower maintenance costs.
Q: Why are ground gears quieter than shaved gears?
A: Shaving is a "cold processing" method that leaves regular tool marks, causing air entrapment and micro-vibrations during meshing. Grinding is a "finishing" process that removes post-heat treatment distortion and corrects shaving marks, creating a smoother, more accurate involute profile. This results in pure rolling friction instead of sliding friction, hence lower noise and higher efficiency.
