618/630F1

The 618/630F1 is a performance-optimized single-row deep groove ball bearing of the 618 series with an ultra-large specification. Its core positioning is to be a highly reliable and precise supporting bearing for ultra-large heavy-duty and harsh industrial equipment. Based on the 630mm inner diameter, 780mm outer diameter, and 69mm ultra-large size foundation, the suffix "F1" corresponds to a structure reinforcement and material compatibility design, which further enhances the impact resistance, deformation resistance, and high-temperature working condition adaptability. It can stably bear ultra-large radial loads and bidirectional axial loads, and can calmly handle harsh scenarios such as continuous operation of heavy machinery, frequent start-stop, and fluctuating working conditions. It also balances long-term durability and precise operation stability. It uses high-carbon chromium bearing steel as the main body (optimized through special heat treatment) and high-strength customized metal cages. The structural design is in line with the core transmission requirements of ultra-large equipment. Installation and maintenance are convenient and the adaptability is strong. It can be integrated into the key transmission system without complex modifications, providing stable, reliable, and long-lasting support and protection for core parts of equipment such as metallurgical heavy rolling mills, large-scale mining crushers, ultra-large reducers, port heavy cranes, and power giant rotors.
