618/1120

The bearing 618/1120, as a large-sized single-row deep groove ball bearing, is primarily designed to provide high-reliability rotational support components for large industrial equipment under heavy-load and demanding conditions. It focuses on scenarios with high requirements for stability and low maintenance, particularly in heavy machinery where stability and durability are crucial. This bearing offers a large inner diameter of 1120mm, an outer diameter of 1360mm, and a thickness of 106mm. It is equipped with a brass cage and a medium internal clearance design, which can withstand radial loads and bidirectional axial loads. It also adapts to certain high-speed operation requirements due to its low friction characteristics. Without frequent maintenance, it can maintain stable performance, significantly reducing equipment downtime costs and failure risks. The application scenarios of this bearing are clearly defined. It can be used in general industrial machinery such as electric pumps and centrifugal pumps, and also meets the operation requirements of high-temperature equipment in steel mills, such as rolling mills and continuous casting lines. It can also be adapted to key components in the chemical industry, such as compressors and turbines in power generation, with high thermal intensity. Through stable supporting performance, it avoids equipment shutdown due to bearing failures, thereby ensuring the continuity and safety of industrial production. It is an important basic component for ensuring efficient, safe, and long-term operation of equipment in the heavy industry sector.
