    Rollers

    Weigh

    BBCP weigh rollers are designed to be used on conveyor weightometers where minimal vibration and idler concentricity are critical. They are typically also utilised on the weightometer lead-in and lead-out rollers to ensure belt stability through the weighing zone. BBCP weigh rollers comprise steel bearing housings and a steel shell, which are welded together. This ensures there is no risk of housings separating over time from factors including heavy loading, moisture ingress and thermal expansion. The bearing housing is designed in a way that ensures that, in the event of shell failure, the traditional sharp edge that can “pizza cut” the belt doesn’t exist.

     

    BBCP weigh rollers are supplied with 2RS NSK greased-for-life bearings and include double-sided triple-labyrinth seals, plus a dust seal which also includes a labyrinth seal. Weigh rollers are suitable for heavy duty applications, in materials handling applications ranging from the smallest quarries up to major mining operations (iron ore, hard rock, black coal, etc,). Weigh rollers are suitable for underground applications. They are powdercoated as standard and can be coloured to your choice.
