Specifications

B series helical bevel gearbox is a completely new design. Outstanding innovations: More sizes with reduced variety of parts; Higher operational reliability combined with increased power capacity; Flanged output shafts facilitate assembly of gear reducer in confined spaces.  

B Series High Power Gear Units is a brand-new model of rigid tooth flank gear reducers with wide application areas, which has the feature of large torque range, a design of unit structure modulization capable of horizontal mounting and vertical mounting, three kinds of output shafts --- solid shaft, hollow shaft and hollow shaft with shrink disk. With carbureted high-strength good-quality alloy, the series has the feature of high-efficiency and long life-span, high permissible axial and radial loads, low noise, high reliability and compact structure and so on.
