Single stage NORDBLOC.1 helical gear unit



NORD DRIVESYSTEMS has extended its successful NORDBLOC.1 series with a single stage gear unit for applications with high speeds and torques.



The new single stage NORDBLOC.1 helical gear unit from NORD DRIVESYSTEMS was specially designed for applications with high speeds and torques. The gear unit is especially robust, efficient, quiet and compact.

The new NORDBLOC.1 helical gear unit features ultimate efficiency, high torsional rigidity, low running noise and long service life. In addition, they also meet even the most stringent hygiene requirements thanks to their wash-down design. The innovative gear units do not have any separating joints or closing caps. This increases the stability of the product and at the same time provides a smoother surface on which neither liquids nor solid materials can accumulate.


The FEM-optimised 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 aluminium 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.






NORD DRIVESYSTEMS develops, produces and sells drive technologies with around 3.600 employees, and is one of the international leaders in the industry. In addition to standard drives, NORD supplies application-specific concepts and solutions, even for special applications, for example with energy-saving drives or explosion-protected systems. Gross sales amounted to approx. EUR 630 mn in the 2017 business year. The company founded in 1965 now has over 36 subsidiaries worldwide. The closely meshed sales and service network ensures optimum availability for short delivery times and customer-oriented services. NORD produces a wide variety of drive units for torques from 10 to 200,000 Nm, electric motors with powers from 0.12 kW to 1,000 kW as well as the necessary power electronics in the form of frequency inverters and servo controllers. Inverter solutions are available for classical installations in the switch cabinet and for decentralised and fully integrated drive units.
