NORD DRIVESYSTEMS has extended its range of single stage NORDBLOC.1 helical gear units to include three larger sizes.

The addition of these new drive units provide high output torques as well as maximum radial and axial load capacity. With its single stage NORDBLOC.1 helical gear units proving popular thanks to improved efficiencies and along service life, the company says the inclusion of three larger sizes is a logical step

Nord said it has received great response from the market on this product and as such, the three new products (SK 871.1, SK 971.1 and SK 1071.1) offer enhanced powers from 0.12 to 45 kW and cover the torque range up to 1,000 Nm.

Thanks to optimised bearings, the units can reliably handle large axial and radial forces. The robust, cast iron gear units are therefore optimally suitable for pumps and agitators. They 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. The modular design provides wide application flexibility due to numerous configuration and mounting options. 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, says Nord.
