heavy load drum motor / for light-duty applications / for conveyors
320L, 320M, 320H



  • Options:

    for heavy loads, for light-duty applications, for conveyors

  • Diameter:

    320 mm (12.6 in)

  • Width:

    400 mm (15.7 in)


To match your requirements in diameter 320 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.
