  3. Roller Production (Casting/Forging & Machining):

    For metallic rollers (aluminum, cast iron), the process involves either casting (pouring molten metal into molds) or forging (shaping metal under immense pressure) to create robust blanks. These blanks then undergo CNC machining to achieve precise dimensions, surface finish, and bearing seat tolerances. Nylon rollers are typically injection molded or machined from extruded rods. The smooth, low-friction surface is critical to prevent cable abrasion.

  4. Surface Treatment and Coating:

    Galvanized steel frames receive hot-dip galvanization or powder coating for enhanced corrosion resistance, particularly crucial for petrochemical and marine applications. Aluminum frames may be anodized. Rollers might be polished or coated with specialized low-friction materials. This step is vital for extending the service life of the roller, especially in harsh outdoor or industrial environments.

  5. Assembly:

    Precision bearings are pressed into the rollers, which are then mounted onto axles within the frame. All fasteners are secured, and movable parts are lubricated. This stage ensures smooth rotation and robust connection of all components.

  6. Testing and Quality Assurance:

    Each finished straight cable roller undergoes rigorous testing. This includes load capacity testing (e.g., in accordance with ISO 12100), rotational friction tests, dimensional accuracy verification, and material integrity checks. Fatigue testing and environmental simulation (e.g., salt spray tests for corrosion) are also conducted on sample batches to ensure compliance with international standards like ISO 9001 and ANSI specifications. The target service life for our rollers typically exceeds 10 years under normal operating conditions, attributed to superior material selection and manufacturing.

This meticulous process ensures that each straight cable roller delivers superior performance, energy saving by reducing pulling force, and exceptional corrosion resistance, making them ideal for target industries such as petrochemical, metallurgy, water supply & drainage, and power transmission.
