NORD SK 92172.1 NORDBLOC.1® Bevel Gearmotor
The NORD SK 92172.1 is a highly efficient, 2-stage right-angle helical-bevel gearmotor from NORD DRIVESYSTEMS' flagship NORDBLOC.1® washdown catalog[cite: 23]. Featuring a smooth, corrosion-resistant die-cast aluminum UNICASE housing[cite: 23], the SK 92172.1 offers right-angle mechanical efficiency exceeding 95%, low noise generation, and long bearing operational life without external parting lines[cite: 23]. Available across a complete range of mounting configurations—including hollow shaft keyway (SK 92172.1 AH), B5 flange (SK 92172.1 AF), B14 flange (SK 92172.1 AZ), shrink disc (SK 92172.1 ASH), GRIPMAXX™ keyless bushing system (SK 92172.1 AM), and nsd tupH™ surface conversion[cite: 23]—it is extensively specified across food & beverage processing, airport baggage handling, parcel sorting conveyors, and automated warehouse logistics[cite: 23].
