Premium Efficient Gearbox


The next generation of premium efficient gearbox from NORD Drivesystems has been released for the North American market. The two stage helical-bevel design, referred to as the 92.1 Series, offers high-performance, up to 97% efficiency and a 60% increase in torque to weight ratio over the previous series. The series is available in five gear case sizes and is characterized by an open, smooth, self-draining outer surface. The 92.1 Series, easily identified by its high-strength lightweight design, is a universal housing offering foot, face (B14) and shaft mount as standard.

  • Universal foot and flange-mount housings
  • Easy wash-down solution
  • Cost effective design
  • Foot, face (B14) and shaft mount
  • External surfaces connected with large radius and generous mold release slopes provide for a cleanable, drainable housing
  • An optional B5 mount is available.

Designed using FEM (Finite Element Modeling Technology), this high-strength aluminum alloy housing is manufactured using NORD's UNICASE™ Design. The UNICASE™ design consists of a one-piece housing where bores and mounting faces are machined in one step, producing precise tolerances that ensure accurate positioning of gear teeth, bearings and seals. Internal reinforcements inside the gear case increase the strength and rigidity of the gearbox, resulting in a high-strength housing. This, in turn, provides for larger, high-capacity output bearings, increased overhung load capacity and increased hollow bore capacity. By NORD offering a leak-free design, longer gear and bearing life, quiet operation and high output torque capabilities, the customer benefits from high efficiency, low maintenance and a long service life.Available with either a NEMA or IEC input, a NORD motor or brake motor, the 92.1 Series is well suited for applications in the conveyor industry, material handling, car wash, and the food & beverage industry, including wash down environments. While a typical worm gear type drive may be 70% efficient, the 97% efficiency of the 92.1 Series is truly the premium efficient gearbox.


  • up to 97% efficiency
  • 60% increase in torque to weight ratio
