618/900F1

The 618/900F1 is a specially customized model of the 618 series extra-large deep groove ball bearing. Its core function is to provide a more adaptable and stable rotational support for the critical rotating mechanisms of large heavy-duty industrial equipment. Built upon the 618/900 base model, with the optimized carbon steel solid cage structure corresponding to the post code F1, this bearing further enhances the structural rigidity and adaptability of the bearing under heavy-load conditions. It is specifically designed to match the transmission scenarios of ultra-large-sized shaft components with specific requirements for bearing cage material and load-bearing stability. In this model, the "6" clearly indicates the basic attribute of the deep groove ball bearing, featuring a simple structure and convenient installation. The 900mm ultra-large inner diameter can precisely meet the assembly requirements of large equipment shafts. Combined with a size design of 1090mm outer diameter and 85mm width, it can adapt to the large-sized transmission system installation space of heavy machinery. The cage made of carbon steel, combined with the ring and balls made of GCR15 high-carbon chromium bearing steel, ensures overall high strength and high wear resistance. The adaptability of the carbon steel cage enables the bearing to more stably constrain the movement of rolling elements under heavy-load conditions, reducing impact losses during operation. It can stably withstand radial loads and certain axial loads under heavy loads. Its applicable scenarios cover industries such as metallurgy, wind power, mining, and heavy machinery manufacturing. It is commonly found in critical parts of steel mills' heavy-duty transmission devices, main shafts of large wind turbines, and rotating components of mining machinery. It can not only meet the stability requirements of equipment for long-term continuous operation but also reduce the maintenance frequency under special conditions through optimization of adaptability. Combined with its spot supply advantage, it provides reliable core rotational component support for the efficient operation of related industry's large equipment.
