618/1060M

The 618/1060M is a high rigidity heavy-duty model of the 618 series extra-large deep groove ball bearings. Its core positioning is to provide "strong bearing capacity + high rigidity + wide adaptability" reliable rotational support for the key rotating systems of ultra-large industrial equipment. It is specifically designed to meet the core requirements of the structural strength and operational stability of the bearing for the bearing structure and operation stability under heavy load and continuous operation conditions of the special large-sized shaft components. The "6" in this model clearly indicates the basic attribute of the deep groove ball bearings, which can withstand both radial loads and certain bidirectional axial loads, and is suitable for multi-load conditions; the 1060mm ultra-large inner diameter, combined with a 1280mm outer diameter and 100mm width size design, precisely meets the assembly space requirements of the shaft components of ultra-large equipment and meets the installation adaptation requirements of heavy machinery. The post-numbered code "M" represents the brass solid cage structure, which significantly improves the structural rigidity and rolling body constraint stability under heavy load conditions compared to the conventional cage, effectively avoiding cage deformation or damage during high-load operation, and extending the bearing service life; the rings and balls use GCR15 (AISI 52100) high-carbon chromium bearing steel, which combines ultra-high strength, high wear resistance and impact resistance, and can stably withstand the continuous high load brought by ultra-large equipment, suitable for harsh industrial environments such as metallurgy, mining, etc. This bearing is widely used in ultra-large heavy-duty transmission devices of metallurgical steel plants, main shafts of large power wind turbines, core rotating components of heavy machinery in mining, large power systems of shipbuilding, and extra-large general machinery industries, and is suitable for the key rotating shaft parts of ultra-large equipment. It can not only meet the long-term stable operation requirements under ultra-large size and high-load conditions, but also reduce the frequency of equipment shutdown and maintenance through the high rigidity structural design, providing core rotational component support for the efficient and reliable operation of ultra-large industrial equipment.
