NORD NORDBLOC.1 helical gear unit

The single-stage NORDBLOC.1 helical gear unit from NORD DRIVESYSTEMS has been specifically designed for applications with high speeds and torques. The gear unit is especially robust, efficient, quiet and compact.

The NORDBLOC.1 helical gear unit features high efficiency, high torsional rigidity, low running noise and a long service life. In addition, it meets stringent hygiene requirements due to its washdown design. It does not have any separating joints or closing caps, increasing the stability of the drive and at the same time providing a smoother surface on which neither liquids nor solid materials can accumulate.

Bores and mounting faces are machined in one step, enabling precise tolerances — thus ensuring accurate positioning of gear teeth, bearings and seals — and an overall longer life for all components. The housing is made from high-strength, corrosion-resistant aluminium and is therefore lightweight and robust.

A 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 NORDBOLOC.1 is 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.
