    Introduction: Powering Durability in Demanding Industrial Environments

    At VIIPLUS, we redefine reliability with ​CuSn8 Graphite-Reinforced Bronze Bearings – precision-engineered components built to excel in high-load, low-speed applications. Combining the superior strength of ​CuSn8 tin-bronze alloy with graphite’s self-lubricating properties, these bearings deliver unmatched wear resistance, reduced friction, and extended service life. Ideal for construction, marine, and automotive industries, VIIPLUS bearings ensure your machinery thrives even in the harshest conditions.


    Why VIIPLUS CuSn8 Graphite Bronze Bearings? Key Features

    1. CuSn8 Bronze Alloy + Graphite Reinforcement

    • High Load Capacity: Supports static loads up to ​120 N/mm² and dynamic loads of ​40 N/mm².
    • Self-Lubricating Graphite: Reduces friction by ​30%, minimizing wear and eliminating frequent lubrication needs.
    • Corrosion Resistance: Thrives in moisture-rich, abrasive, or chemically aggressive environments.

    2. Wrapped Design for Enhanced Protection

    • Contaminant Resistance: Shielded construction prevents debris ingress, extending component lifespan.
    • Secure Installation: Flanged and cylindrical variants (e.g., ​FB092, ​WB700) ensure stable fitment in H7 tolerance housings.

    3. Versatile Applications

    • Heavy Machinery: Excavators, cranes, and winches.
    • Automotive & Transport: Trucks, tractors, and trailer axles.
    • Marine & Underwater: Pelletizer machines and submersible equipment.
