The FEM-optimized UNICASE housing ensures maximum strength and rigidity. In addition to increased rigidity, the internally reinforced design also ensures especially quiet running. All bearings and seal seats are contained within the casing, eliminating joints which can weaken the housing and allow oil leakage. Bores and mounting faces are machined in one step, enabling extremely precise tolerances — thus ensuring accurate positioning of gear teeth, bearings and seals, and longer life for all components. The housing is made from high strength, corrosion resistant aluminum and is therefore especially lightweight and robust. Additional protection is provided by the optionally available nsd tupH surface treatment. The smooth, easy to clean housing makes the NORDBLOC.1 gear unit particularly suitable for users from hygienically critical sectors such as the food or pharmaceutical industries.

The gear units are generously dimensioned and can withstand large radial and axial forces. A particular benefit of the large bearings is the larger diameter of the internal shafts, which increases the bearing strength. The gear wheels are made from case-hardened steel and permit high short-term overloads.

The new NORDBOLOC.1 products are available in five sizes with motor powers from 0.12 to 7.5 kW for output torques of up to 280 Nm. All variants are available as flange mounted (B5 or B14), or foot/flange mounted versions. Options for IEC and NEMA motor mounting, as well as a wide range of equipment variants for shafts, bearings, and lubrication can be flexibly implemented.

Robust, efficient, quiet and compact – with the single stage NORDBLOC.1 helical gear unit, NORD has created a reliable, robust and economical drive solution for pumps, mixers, and fans, as well as for conveyor technology applications.
