National Plastics & Rubber is proud to be at the forefront of manufacturing Bearingless Roller Systems designed for use in draglines, shovels, and other mining equipment. Our innovative approach addresses the common drawbacks of traditional roller systems, offering significant advantages in safety, efficiency, and cost-effectiveness.
The Limitations of Traditional Roller Systems
Conventional rollers consist of polyurethane bonded to a solid shaft that rotates on bearings. While commonly used, this design has several inherent drawbacks:
- Quick Wear and Tear: Polyurethane on traditional rollers wears unevenly due to rope contact, often requiring full replacement despite localised damage.
- High Replacement Costs: Because the entire roller is bonded to the shaft, replacing a worn segment involves removing and replacing the whole unit, a costly process that demands cranes or heavy equipment.
- Stock Requirements: To minimise machine downtime, multiple spare roller systems must be kept in inventory, increasing storage costs and complexity.
- Bearing Seizure: Bearings can seize, leading to roller failure and accelerated rope wear.
The Advantages of Bearingless Roller Systems
National Plastics & Rubber’s Bearingless Roller Systems were engineered to overcome these challenges and offer numerous benefits:
- Easy, Cost-Effective Replacement: Our lightweight polyurethane segments (averaging 8 kg) can be manually handled, eliminating the need for cranes or other heavy lifting equipment and reducing downtime.
- Standardised Segments: We promote the use of uniform segments across various machine areas, streamlining inventory management and reducing the need to stock multiple sizes.
- Segment Rotation Capability: Worn segments can be rotated to a different position and reused as spacers, maximising the life of each component and minimising waste.
- Bearing-Free Design: By removing the need for bearings, our system avoids bearing maintenance issues and comes pre-greased for smooth operation.
Commitment to Innovation
At National Plastics & Rubber, we are dedicated to continuous improvement and innovative solutions tailored to meet the unique challenges of our clients. Our state-of-the-art design facilities allow us to customise products to specific requirements, ensuring optimal performance. Recently, we developed a custom roller system to enhance the continuous movement and rotation of segments, demonstrating our commitment to advancing industry standards.
