The new units have a power range of 30 to 60 hp, a torque range of 3540 to 8850 lb-in. and a ratio range of 1.41 to 8.09:1. With UNICASE cast iron housing and optimized bearings, they can reliably handle large axial and radial forces and are well suited for pumps, mixers, conveyors, and industrial fans. Single-stage compact gear units offer increased thermal performance, increased bearing ratings, and more compact designs. Eight single-stage helical gear unit sizes are included in the NORDBLOC line. Mounted by foot, flange, or a combination of both, and available with solid shafts with metric or imperial extensions, the line provides customizable, flexible solutions for most high-speed drive applications. Gear units may be ordered with an integral motor or with IEC or NEMA C-face motor adapters.
