1. The case made of spheroidal graphite casting is rigid, flat and beautiful after going through multi-dimensional machining.
2. The driving devices of the reduction gearbox and the distributor box are respectively manufactured with ordinary steel and ultra-strength alloyed case-hardened steel as well as the carburizing, quenching and gear grinding technology. The key parts are added with the surface peening process. Hardness of Tooth Surface: HRC54~62, Hardness of Core: HRC30~40, Gear Precision: Grade 6. High efficiency, high strength and low noise
3. The designed life of the bearing is between 20, 000 to 50, 000 hours.
4. The external forced lubrication and cooling system strengthen the lubricating and cooling effect, featuring reliable operation and convenient maintenance.
