Planetary Slewing Drive Planetary Gearbox

Superior Performance

The replacement of the NB700S slewing drive gearbox is specifically designed for pinion and slewing ring drives. Successfully employed on tower cranes, shipboard and harbor cranes, wind generators, and steering drives on ship propulsion systems, the planetary gear unit can be used in almost all applications where accurate positioning is required. These planetary slewing drives are suitable for the most demanding duties in any environment.

The design of the gearbox optimizes torque performance and radial load capacity in order to perfectly mesh the pinion and ring gear. For accurate adjustment, some versions have eccentric mounting between the pinion axis and the casing axis. Their wide range of ratios enables the selection of motor size and type which best suits the customer's requirements and application.

Technical data and installation dimension of NB700L Series gearbox are the same as those of Bonfiglioli 700T Series

NB700L Series gearboxes can be used interchangeably with the following models of Trasmital Bonfiglioli

NB706S2                                                               NB706S2

Technical data and installation dimensions of NB700S Series gearbox are the same as those of Rexroth GFB Series

I nostri riduttori epicicloidali, riduttori per ruote, riduttori per argani, riduttori per cingoli possono essere alternativi ai riduttori Bosch Rexroth.

Nota: I nostri riduttori epicicloidali, i riduttori per ruote, i riduttori per argani e i riduttori per cingoli sono esattamente identici a quelli di Bosch Rexroth per quanto riguarda le dimensioni di installazione e quasi identici a quelli di Bosch Rexroth per quanto riguarda i parametri di prestazione.
