Precision Mine Duty Drum Pulleys were originally designed for the rugged environment of underground coal mining. Their ultra heavy duty rigid construction has been proven in the toughest conveyor applications. The "good as the shaft" design of Precision Mine Duty Drum Pulleys make them particularly useful for spares or replacement pulleys in critical positions. The Precision Mine Duty Pulleys are available in diameters from 10" to 60" and face widths from 20" to 66". Available with various hub and bushing systems.

The toughest conveyor applications require ruggedness offered by a Precision "HDD" Heavy Duty Drum Pulley. Steel rims, hubs and discs are fused into an integral component by a continuous submerged arc welded bond that maximizes pulley strength, balance and concentricity. The use of internal discs, plus heavier than standard construction reduces radial deformation of the rim and longitudinal deflection of the rim and shaft. The "HDD" pulley is available in standard face widths from 12" to 66" and standard diameters from 10" to 60" - intermediate sizes are available upon request. Available with various hub and bushing systems.
