Motorized Pulley 138LS
Motorized Pulley diameter 138 mm – Length min. RL 300 mm and power between 0.10 and 1.0 kW.
Motorized Pulley 138LS, with machined helical gear box, performs an efficiency, in a compact diameter of 138 mm only. With a min RL of 300 mm and powers ranging from 0.10 to 0.75kW this size of motorized pulley is suitable for most duties requiring such a small diameter – e.g.:
- Light agriculture and bulk solids handling conveyors
- Mobile or portable conveyors
- As a drive unit for brush cleaners etc.
Motorized pulley 138E has standard IP66/67 enclosure and is available in complete stainless steel execution
for wash down application.
For the choice of the Motorized Pulley it is very important to know or to calculate the belt tension T1+T2 (radial load). This MUST NOT OVERCOME the “max. radial load” allowed as shown in the catalogue.
Be careful to very high belt tensions when using thick, heavy and/or large belts.
If the type 138E cannot provide the necessary max. radial load T1+T2, you have to choose a Motorized Pulley with a bigger diameter.
Motorized Pulley 165LS
Motorized Pulley diameter 165 mm – Length min. RL 400 mm and power between 0.11 and 2.2 kW.
Motorized Pulley 165LS, with machined helical gear box, performs an efficiency, in a compact diameter of 165 mm only. With a min RL of 400 mm and and powers ranging from 0.11kW to 1.5kW this size of motorized pulley is suitable for most duties requiring such a small diameter – e.g.:
- Light agriculture and bulk solids handling conveyors
- Mobile or portable conveyors
- As a drive unit for brush cleaners etc.

Motorized Pulley 220M & 220H
Motorized Pulley diameter 220 mm – Length min. RL 400 mm and power between 0.37 and 5.5 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.

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.
