   • Rubber Compounds: Custom-formulated rubber is chosen based on application requirements. Options include natural rubber for excellent abrasion resistance, SBR for general purpose, NBR for oil resistance, EPDM for weather and ozone resistance, and neoprene for flame retardation. These compounds are prepared with specific additives to optimize hardness (typically 60-70 Shore A), elasticity, and environmental resilience.
2. Shaft Machining:

   High-precision CNC machining is employed to cut and shape the steel shafts to exact dimensional tolerances. This ensures perfect alignment with bearings and housings, critical for smooth rotation and extended service life. Forging may be used for heavy-duty shafts to enhance strength.

3. Shell Fabrication:

   Steel plates are cut, rolled, and seam-welded (e.g., submerged arc welding) to form the cylindrical roller shell. Strict quality control ensures uniform wall thickness and concentricity, preventing vibration and premature wear on the `conveyor belt roll`.

4. Bearing Housing Assembly:

   Bearing housings, often stamped or cast, are welded to the ends of the roller shell. This step requires precise alignment and strong, clean welds to secure the bearings. Advanced sealing systems (multi-labyrinth, contact seals) are incorporated here to protect the bearings from dust, moisture, and contaminants, significantly extending the service life of `conveyor idlers`.

5. Rubber Lagging/Vulcanization:

   The prepared rubber compound is applied to the steel shell using either cold bonding or, more commonly, hot vulcanization. Hot vulcanization involves high pressure and temperature to chemically bond the rubber to the steel, creating an inseparable and highly durable covering. This process ensures exceptional adhesion and uniform thickness, critical for the performance of `belt conveyor roller types`.

6. Surface Finishing and Balancing:

   After vulcanization, the rubber surface is often ground to achieve precise dimensions and a smooth finish. Dynamic balancing is then performed to eliminate any eccentricities, minimizing vibration and noise during operation, thereby extending the life of both the roller and the conveyor belt itself.

7. Quality Control and Testing:

   Each `belt conveyor roller` undergoes rigorous testing, adhering to international standards such as ISO (e.g., ISO 1536 Conveyor belts – Test methods for wear resistance, ISO 9001 for quality management) and ANSI/CEMA standards (e.g., CEMA B105.1 for conveyor idlers). Tests include dimensional accuracy, run-out, static and dynamic balancing, seal effectiveness, rotational resistance, and load capacity. This ensures a reliable service life of 50,000 to 100,000 hours or more under optimal conditions.
