HB helical gear box flender gear box

It is a completely new design. And its advantages are:
1.) Highly standard modular designed, more sizes with a reduced variety of parts.
2.) Higher operational reliability combined with increased power capacity.
Mounting position
The gear units can be supplied for either horizontal or vertical installation. Other arrangements are also possible on request.
Long service life
"Under the condition of accueately selecting type size and the normal maintenance and use, main components (expect those easily disabled parts) can last as long as up to more than 50,000 hours.Low noise
All key components are finished by precisely machining; grinding the gears; designing noise absorbing housings; accurate assembly, and finally tested, and therefore, fairly low noise is reached.
