NORD Bevel Geared Motors are the best choice wherever high speed ratios and torques are required. Our drive systems, consisting of an electric motor and a bevel gearbox, are especially suitable for use on conveyor belts as well as in intralogistics and packaging technology.

NORD Bevel Geared Motors
Regardless of whether you choose the lightweight or the robust version: bevel gearboxes from NORD DRIVESYSTEMS operate with ultimate efficiency over the entire range of speed ratios.

Further advantages of NORD Bevel Geared Motors:

  • Powerful
    They achieve torques of up to 50,000 Nm
  • Corrosion Protection
    Optional surface treatment with nsd tupH protects the Bevel Geared Motors even in harsh environments (2-stage bevel gearbox).
  • User-friendly
    The easy to clean wash-down version ensures cleanliness (NORDBLOC.1).
  • Flexible
    The direction of rotation between the input and output shaft can be easily reversed.

Gearbox Selection

Below are some guideline steps to help aid in
the gear unit selection.
1. Determine the speed and/or gear ratio (see order form)
2. Determine the required power or torque (see order form)
3. Determine Service Factor
4. Select the basic gearbox type and input
5. Determine the required mounting position
6. Select options
7. Checks – overhung load, thrust load, NEMA motor weight, thermal considerations, and other application considerations
