Other information about the product
Motorized Pulley 320L, 320M & 320H, Ø320 mm
To match your requirements in diameter 320 mm, our product range offers three different loading performances for your BULK applications:
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
320L is meant for applications with regular and constant operating conditions. Max. allowable radial load has to be respected; therefore it is advisable to rubber lag these Pulleys to increase grip and to limit belt tension.
320L should NOT be used for e.g. feeder conveyors. (Motor/gearbox origin from 220M).
M for Medium-duty
The internal parts of 320M are designed for TOUGH and IRREGULAR working conditions - e.g. in crusher & screening applications, asphalt, cement and concrete plants etc.
H for Heavy-duty
Due to a solid 3-stage gearbox, Ø 50 mm shafts, matching bearings etc, 320H provides the necessary forces needed for low speeds combined with high power, and is designed to handle irregular loadings in BRUTAL conditions.
