Deft design: Small volume; Simple Installation; Wide utilization.
Suitable for all types of mounting positions
ES .. and ERF .. conjoined combination for special low rate.
2 Material
Housing: High power cast iron HT250, die casting lumen, decrease the abrasion of parts.
Gears: 20CrMo, Carbonitriding, Tooth hardness: HRC 60 after grinding.
Flat keys: C45, Surface hardness: HRC 50.
3 Gear Unit Efficiency
High precision equipment; seals; bearings;Effectively reduces friction; Stage performance of gear drive 
reaches 97%.
For some means of mounting, the input gear is totally immersed in the lubricant, please consider the churning loss with regards to big frame size and high input velocity .
