Heavy-Duty HDPE Rollers

For use in extreme environments: Iron Ore, Hard Rock, Gold Mining, Bauxite and all other extreme, moist and dusty environments.
Megaroller HDPE Rollers are an innovation in reinforced high-density polyethylene (HDPE) conveyor rollers. Utilising Megaroller’s unique design and incorporating our patented Sealing Arrangement, Bearing and Seal Housing, and Roller Shell, Megaroller HDPE Rollers are a robust, long-lasting and ecologically-sound alternative to conventional steel rollers. All plastic components have been designed in-house and is produced in our factory.
Our HDPE rollers are recognised as the market’s most esteemed roller. The Megaroller design results in unprecedented performance and a market leading lifespan. 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.
- Unique patented fusion process: The roller body is heat fused to the bearing housings, which results in a totally sealed and aligned roller drum.
- High quality lubricant. Megarollers are lubricated for life.
- Only the best quality bearing brands (SKF or FAG) are used in our products.
Perfectly Concentric Design:
- Internal circumference of the roller bodies are precision machined by calibrated machinery to align bearing housings, ensuring bearing alignment.
- Roller Bodies are dynamically balanced and machined to a perfect concentricity – Reduced vibration, noise & extended bearing life, which translates into lower repair and maintenance costs.
- The final result is a roller, which conforms to the highest specification, with concentricity tolerance (TIR) of 0,2mm.
Energy Efficient:
- Lighter weight of the HDPE rollers means a ‘low breakaway’, thus a 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:
- Highly resistant to wear by abrasion.
- The HDPE roller body is reinforced with a 2mm steel tube resulting in a heavy duty application roller.
- Designed to operate in extreme temperatures, harsh operating conditions, and in highly-corrosive chemical or coastal conditions.
Reduced Roller Mass:
- Up to 40% lighter than Steel Rollers.
- Minimise the risk created by manual handling.
- Lower breakaway mass saves start-up cost and power requirements.
100% Belt Friendly:
- HDPE does not damage belt. Its frictional characteristics results in less build up and decreased abrasive action on conveyor belts.
Available in:
Standard
Megaroller’s standard roller incorporates all the advantages of the Megaroller design.
Anti-seize
The roller uses Megaroller’s innovative anti-seize technology, comprising a side flinger which remains static while the roller is running.
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.
