HDR heavy-duty conveyor rollers are engineered to deliver high-performance and extended service life (typically 8 years with 24/7 operation) in demanding bulk material handling environments. Their robust design incorporates premium-quality components and materials:
HDR conveyor rollers are specifically designed for open mining applications and are ideal for handling a wide variety of bulk materials. The standard design can be tailored to meet specific customer requirements, with options including mass-limited versions, varying shell thicknesses, lagging for aggressive or corrosive environments, and additional sealing for extreme conditions. Custom configurations are also available, including different types of garlands for belt speeds up to 10 m/s.
These rollers excel in the most challenging conveyor systems, including those in mining, quarrying, cement production, coal power generation, and dock operations. Available in multiple configurations, their heavy-duty steel construction, combined with a sophisticated hermetic sealing system with multiple labyrinth seals, ensures superior load capacity and resistance to impact, corrosion, and abrasion. HDR rollers are designed for extreme environmental conditions, operating reliably between -20°C and +100°C with standard lubrication, and can withstand even harsher temperatures with specialized greasing.
Material handling components ideal for mining applications that require flexibility while guaranteeing durability and safety during transportation.
High-quality material handling components for conveyor systems that offer unrivalled service continuity.
Products that are made to last: material handling components for conveyors resistant to various types of corrosive agents.
Plus
The Extra Heavy Duty Rugged Roller is designed for the most demanding conveyor applications, capable of handling extreme loads and harsh conditions. Its reinforced construction ensures maximum durability and resistance to impact, abrasion, and heavy wear. Built with high-quality materials, these rollers are engineered to provide superior performance in industries such as mining, cement production, and bulk material handling. Their robust design ensures they maintain efficiency even in the most challenging environments, providing long-lasting service with minimal maintenance
The bearing housings of these rollers are either forged or massive, welded steel constructions, offering unmatched strength and precision. Manufactured with high tolerances, these housings ensure perfect alignment and secure bearing placement, providing superior load distribution and stability. The welded design adds extra durability, making these rollers ideal for heavy-duty applications where high impact and continuous operation are common. This design also allows for better protection of internal components, enhancing the roller’s overall longevity and reliability in tough working conditions
The multi-stage labyrinth non-contact seals featured in these rollers provide advanced protection against dust, dirt, and moisture, ensuring optimal performance in extreme environments. This sealing technology minimizes friction and prevents contaminants from entering the bearing housing, significantly extending the lifespan of the roller. The non-contact design reduces wear and running resistance, allowing for smooth and efficient operation, even at high speeds and under heavy loads. With low running resistance, these rollers contribute to energy efficiency and reduced maintenance, making them a reliable choice for demanding conveyor systems
