The oil-cooled motorized pulley integrates the motor, reduction gearing and conveyor drum into one sealed, compact unit. With drum diameters from 320 to 1000 mm and belt widths from 500 to 1400 mm, it replaces the exposed motor-gearbox-chain arrangement on belt conveyors, freeing space at the drive end and removing the guards, alignment work and lubrication points that a conventional drive requires.
The motor and gearing run inside the drum in an oil bath: the oil carries heat out to the shell and lubricates the gear train at the same time, which is why this design holds up on long continuous runs in cement plants, mines, quarries and bulk terminals. The sealed shell keeps dust and wash-down water away from the electrical parts, and the plain outer surface sheds material instead of trapping it.
We select the drum diameter, belt width, belt speed and power together rather than quoting a pulley in isolation. Drum lagging type and thickness, shaft ends, bearing arrangement and the required belt pull are confirmed against your conveyor data before release, and the terminal box and cable entry are positioned for the site layout. Oil grade is matched to the ambient temperature range.
Each pulley is assembled, filled and run-tested before packing. We can consolidate pulleys, idlers, belts, backstops and conveyor chain into a single shipment so one container covers the whole drive and wear-part package. Lead time is confirmed against the configuration at quotation.
Send us your belt width, belt speed, centre distance, material and required power, plus any lagging preference. We will confirm the drum size and shell loading and return a complete drive selection with a quotation.
