618/900

The 618/900 is the core model of the 618 series of oversized deep groove ball bearings. Its core function is to provide high-load-bearing and stable rotational support for the critical rotating parts of large heavy-duty equipment. It is specifically designed to meet the strict requirements of industrial scenarios regarding bearing size specifications and load capacity. It combines structural reliability and operational adaptability. The "6" in this model clearly indicates its nature as a deep groove ball bearing, offering basic advantages such as simple structure, convenient installation, and low maintenance costs. The 900mm oversized inner diameter design can meet the assembly requirements of large shaft components and is suitable for large-sized transmission systems of heavy machinery. Relying on the high-quality material and precise manufacturing process of GCR15 high-carbon chromium bearing steel, its load-bearing performance is outstanding. It can stably withstand radial loads and certain axial loads under heavy-duty conditions, and also has good wear resistance and impact resistance. It can be adapted to harsh operating environments in industries such as metallurgy, wind power, mining, heavy machinery manufacturing, and shipbuilding. It is commonly found in key parts of large fans, heavy-load transmission devices in steel mills, rotating components of mining machinery, etc., ensuring the long-term continuous and stable operation of equipment, reducing the frequency of downtime and maintenance, and providing core support for the efficient operation of large industrial equipment.
