BT Series Conveyor Roller Bearing - High-Efficiency Solution for Bulk Material Handling

The BT Series Conveyor Roller Bearing is engineered to provide a robust and low-maintenance solution for conveyor systems in bulk material handling applications. Designed for demanding environments, this bearing integrates advanced sealing technology and precision manufacturing to reduce friction, minimize energy consumption, and extend service life. It is an ideal choice for operations seeking to improve system uptime and lower maintenance costs.

Key Features

• Advanced Sealing Technology: Incorporates a multi-lip labyrinth seal design that effectively prevents the ingress of dust, moisture, and other contaminants, which is a common cause of premature bearing failure in conveyor applications. This feature is crucial for maintaining performance in challenging environments like mining, cement, and aggregate processing.
• Robust Construction and Durability: The outer race and inner components are made from high-grade steel, ensuring exceptional strength and resistance to heavy radial and axial loads. This design minimizes wear and tear, significantly extending the lifespan of the conveyor idler roller bearing.
• Reduced Friction and Energy Consumption: Precision-machined raceways and optimized internal geometry lead to lower running torque. This results in reduced energy consumption, contributing to a more sustainable and cost-effective operation. The low-friction design also helps to decrease operational temperatures.

Application Areas

The BT Series Conveyor Roller Bearing is a specialized component for heavy-duty applications, suitable for but not limited to:

• Mining and Quarrying: Use in belt conveyors for transporting ore, gravel, and other raw materials.
• Cement and Concrete Plants: Critical for material handling systems in dusty, high-load environments.
• Grain and Bulk Agricultural Handling: Essential for efficient and reliable operation of grain elevators and conveyor systems.
• Port and Material Terminals: Used in large-scale conveyor belts for loading and unloading bulk cargo.
• Power Generation: Applications in coal-fired power plants for handling fuel.

Frequently Asked Questions

1. How does the BT Series Conveyor Roller Bearing compare to standard deep groove ball bearings in conveyor applications?

The BT Series bearing is specifically designed for the demanding axial and radial loads and severe contamination found in conveyor systems, unlike general-purpose deep groove ball bearings. Our integrated labyrinth seal is engineered to offer superior protection against dust and moisture, a primary cause of conveyor idler failure. While deep groove ball bearings may be less expensive initially, the BT Series provides a significantly longer service life and requires less maintenance, leading to a lower total cost of ownership.

2. What is the expected service life of the BT Series in a high-dust, heavy-load environment, and how can we prevent premature bearing failure?

The service life of the BT Series is optimized for challenging environments, offering a significant improvement over conventional bearings. It is designed to achieve a calculated L10 life of over 100,000 hours under typical conveyor load conditions, largely due to its robust sealing system and high-quality materials. Premature bearing failure in these conditions is most often due to contamination and improper installation. We recommend adherence to proper installation procedures and periodic inspection. For an accurate service life estimation tailored to your specific application, including load cycles and environmental factors, our engineers can perform a detailed analysis and provide a customized recommendation.
