1 Performance Characteristics
helical worm gear Systematic and modular design;Transmission ratio with fine stage covers a wide range.
High efficiency; Low energy intake; Superior performance.
High Precision gearwith teeth grinding;Stable transmission; Low noise; Solid bearing capacity; Long Service 
life.
Deft design: Small quantity; Simple Installation; Wide usage.
Suitable for all sorts of mounting positions
ES .. and ERF .. conjoined combination for special low rate.
2 Material
Housing: High power cast iron HT250, die casting lumen, reduce 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 gear; seals; bearings;Effectively reduces friction; Stage performance of gear drive gets to 97%.
For some ways of installation, the input gear is totally immersed in the lubricant, please consider the churning loss with regards to big frame size and high input velocity .
