Product features: YBF series products follow the philosophy of modularization and optimization; adopt finite element analysis method and unique lower noise technology in designing gear, to insure advanced design. The classification of ratio is so accurate it has millions of combinations to meet varied demand of customers. The process from the material selection to manufacturing is strictly controlled ——box housing is beautiful and rigid casted by precision control, gear is endurable by carburizing. Take the flexible manufacturing control (FMC) in the manufacturing to realize the high precision level and maintenance-free of products.
