Rulmeca operates a Service centre fully dedicated to the repair and assembly of Motorized Pulleys
HDR roller is Rulmeca engineered solution for those extremely bulk material handling applications where extra heavy-duty conveyor rollers are required.
The robust design incorporates premium quality components and material to deliver high-performance and extended service life – typically 8 years with 24/7 operation – in the most demanding conditions and environments:
This heavy-duty construction, combined with the sophisticated hermetic sealing system with multiple labyrinth seals, ensures superior load capacity, resistance to impact, corrosion and abrasion, and reliability under low and high temperatures (between -20°C and +100°C).
HDR roller is specifically design for open mining applications but it excels in the most challeging conveyor systems for handling a variety of bulk materials, including also quarrying, cement production, coal power generation, and dock operations.
The standard design can be tailored to meet specific customer requirements. Options include mass-limited version, varying shell thicknesses, lagging for aggressive or corrosive environments, additional sealing for extreme conditions, specialized greasing for harsher temperatures. Custom configurations are also available, including different types of garlands for belt speeds up to 10 m/s.
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
HDR 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, our roller is engineered to provide superior performance in industries such as mining, cement production, and bulk material handling. Its robust design ensures it maintains efficiency even in the most challenging environments, providing long-lasting service with minimal maintenance
The bearing housings of HDR roller are either forged or massive, welded steel constructions, offering unmatched strength and precision. Manufactured with high tolerances, they ensure perfect alignment and secure bearing placement, providing superior load distribution and stability. The welded design adds extra durability, making our rolle 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 HDR roller 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, our roller contributes to energy efficiency and reduced maintenance, making it a reliable choice for demanding conveyor systems
