Motorized Pulley diameter 220 mm – Length min. RL 400 mm and power between 0.37 and 7.5 kW. Meant for re-cycling (hand sorter conveyors), bunker discharge conveyors and where a combination of slow speed and high torque is required.
To match your requirements in diameter 216 mm, our product range offers two different loading performances for your BULK applications:
- 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.
M for Medium-duty
The internal parts of 220M are designed to match irregular working conditions in applications such as mobile crushing & screening, cement & concrete plants, mobile conveyors and open stone & gravel pits.
220M provide sufficient belt tension.
H for Heavy-duty
A reinforced 3-stage-gearbox provides 220H with the necessary strength needed for low speeds, high torque and the listed belt tension.
220H is popular in re-cycling (hand sorter conveyors), bunker discharge conveyors and where a combination of slow speed and high torque is required.
For the choice of the Motorized Pulley it is very important to know orto calculate the belt tension T1+T2 (radial load). This MUST NOT OVERCOME the “max. radial load” allowed.
Be careful to very high belt tensions when using thick, heavy and/or large belts.
It this type cannot provide the necessary max. radial load T1+T2, you have to choose a Motorized Pulley with a bigger diameter.
