Heavy-Duty HDPE Rollers

For use in any environment: Iron Ore, Hard Rock, Gold Mining, Bauxite and all other extreme, moist and dusty environments.

Megaroller Hybrid Rollers are unique combination steel/high-density polyethylene (HDPE) conveyor rollers. Megahybrid Roller provide the desired attributes of steel rollers, without the negative characteristics of a steel-based bearing housing.

Some advantages are:

Ultimate Bearing Protection:

  • Advanced Sealing Arrangement (Patent number 99/5238): The market’s most efficient sealing system. The arrangement is completely water tight and bearings are completely protected from moisture and grit.
    High-impact Bearing and Seal Housing (Patent number 2001/6883): Due to its innovative design, the bearing and sealing housing is able to absorb the impact imposed by uneven loads and belt speed.
    High quality lubricant. Megarollers are lubricated for life.
    Only the best quality bearing brands (SKF or FAG) are used in our products.

Stringent Concentricity Specification:

  • Megaroller only procures high quality roller ERW conveyor tube that confirms to a concentricity tolerance of TIR maximum 0.4mm.

Energy Efficient:

  • Lighter weight than conventional steel rollers. Lower breakaway mass results in significant reduction in energy or start-up costs on conveyor drives.
    Megaroller seal offers a low friction coefficient.
    Energy Efficient bearings ensures a low power demand for conveyors.

Highly Durable Roller Body:

  • The main body is made entirely from steel, which has been trusted in conveyor roller systems for years.
    100% Belt Friendly
    MegaHyrid bearing housings are made from precision injection moulded HDPE. In the event of Bearing failure, HDPE can’t damage the belt.

Megaroller’s standard roller incorporates all the advantages of the Megaroller design.


Anti-static

Our innovative anti-static technology, comprising of a copper strip inside of the roller, which connects the outer shell to the shaft, can be applied to the Megahybrid roller. Static electricity is thus earthed inside the roller, to mitigate the risk of an open spark within methane rich underground mines.


Anti-runback

Our anti-runback conveyor roller can be applied to incline belts to prevent the belt from running back in the event of “belt snap”. The rollers are fitted with a roller brake system which ensure that the rollers only run in one direction.
