Maximum reliability in the most arduous conditions
The Motovario PBH series consists of parallel helical and bevel-helical gear reducers up to 4 reduction stages, conceived to ensure the maximum reliability under the most arduous conditions such as in case of applications with high inertias, overloads, sudden peaks and significant external loads.
Range features enhance the possibility of a high customisation level, for customised solutions satisfying the specifications of the most demanding users, and meeting the requirements with a high technological content.
