Motorized Pulley 500L, 500M & 500H
Motorized Pulley 500L, 500M & 500H, Ø 500 mm
To match your requirements in diameter 500 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
500L is meant for similar applications as 400M except for the fact that the belt requires a larger pulley diameter. (Motor/gearbox origin from 400M).
500L are typically used in grain storage, cement, steel, fertilizer and heavy mobile crushing & screening applications.
As to outer dimensions, 500L cannot replace 500H (Former TM500/TM501).
M for Medium-duty
Using a solid and robust 3-stage gearbox, 500M provides the necessary torque & belt pull needed for low speeds combined with high power for irregular loadings. (Motor/gearbox origin from 400H).
As to outer dimensions, 500M cannot replace 500H (Former TM500/TM501).
H for Heavy-duty
The construction of 500H is the heaviest of this particular range with internal parts such as gearbox, Ø 65 mm shaft, matching bearings etc. are designed for tough, irregular, extreme and brutal working conditions.
