Mid Heavy Duty gear reducers

PBZ

CONTINUOUS DUTY WITH REDUCED MAINTENANCE COSTS

The Motovario PBZ series consists of parallel helical and bevel-helical gear reducers up to 4 reduction stages, characterised by high power density, compact  size, modularity, reliability and a favourable performance/sturdiness ratio.
These industrial gear reducers have been conceived and designed for continuous, critical and particularly arduous applications requiring a high number of accessories, as well as dedicated options for specific fields: PBZ units perfectly meet all these needs, fully satisfying the heavy-duty industry world.
