Motorized Pulley 400L, 400M & 400H, Ø400 mm

To match your requirements in diameter 400 mm, our product range offers three different loading
performances for your BULK applications:

  • L for Light-duty
  • M for Medium-duty
  • H for Heavy-duty

You have a choice

Therefore, it is important to notice the differences to choose the right type of pulley for the right application based on estimated belt tension (radial load) = T1+T2. The actual radial load MUST be LESS than the max. allowable radial load shown in this catalogue.

Be aware of increased belt tensions using multi-ply thick heavy belts and/or larger belt widths.

If you do not find the belt tension needed in this diameter, you might have to choose a larger one.

L for Light-duty

400L is meant for applications with regular and constant operating conditions. Max. allowable radial load has to be respected. A popular application is magnetic separators! (Motor/gearbox origin from 320M).

M for Medium-duty

The internal parts of 400M are designed for tough, irregular and extreme working conditions. 400M are typically used in grain storage, cement, steel, fertilities and heavy mobile crushing & screening applications.

H for Heavy-duty

Due to a solid 3-stage gearbox, 400H provides the necessary forces needed for low speeds, combined with high power, and is designed to handle irregular loadings in BRUTAL conditions.
