1 Performance Characteristics
Systematic and modular design;Transmission ratio with good stage covers a wide range.
High efficiency; Low energy usage; Superior performance.
High Precision gearwith teeth grinding;Stable transmission; Low noise; Solid bearing capacity; Long Program life.
Deft design: Small volume; Simple Installation; Wide utilization.
Suitable for all sorts of mounting positions
ES .. and ERF .. conjoined combination for special low swiftness.
2 Material
Housing: High power cast iron HT250, die casting lumen, reduce the abrasion of parts.
Gears: 20CrMo, Carbonitriding, Teeth 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 efficiency of gear drive reaches 97%.
For some ways 
of installation, the input gear is helical worm gear totally immersed in the lubricant, please contemplate the churning loss with regards to big frame size and high input swiftness .
