The 92.1 and 93.1 Series gearboxes from NORD Gear Corp. (Waunakee, WI) feature a two-stage helical-bevel design. Both series are available in five gear case sizes, and are characterized by an open, self-draining outer surface. The high-strength aluminum alloy housing is manufactured using the UNICASETM design, which consists of a one-piece housing where bores and mounting faces are machined in one step, ensuring accurate positioning of gear teeth, bearings, and seals. Internal reinforcements inside the gear case increase the strength and rigidity of the gearbox.

The 92.1 series is a universal housing offering foot, face (B14), and shaft mount as standard. An optional B5 mount is available. The 93.1 series features a closed design and comes as shaft and flange mount (B14) as standard. Optional drilled and tapped holes can be provided for foot-mount requirements. An optional through-bolt, B5-flange is available.
