61880

61880, as a 618 series large-sized deep groove ball bearing, is primarily designed to meet the stability and adaptability requirements for rotational support in various heavy-duty industrial scenarios. With its large size structure of 400mm inner diameter, 500mm outer diameter, and 46mm width, it combines considerable load-bearing and rotational speed performance to become a reliable rotating component for large industrial equipment. It has a dynamic load of 235kN and a static load of 385kN. Under grease lubrication, the maximum rotational speed can reach 950r/min, and with oil lubrication, it can reach 1200r/min. It can stably withstand large radial loads and certain bidirectional axial loads, and is suitable for the working conditions of long-term continuous operation of equipment. This bearing is applicable in a wide range of scenarios, including heavy industrial equipment such as steel rolling machines and rotary dryers, as well as specialized machinery such as AC welders and belt furnaces. It can also be matched with railway vehicle axles, large motors, and reduction devices, providing stable and efficient rotational support for large equipment in various industries. It also meets the strict usage requirements of core rotating components for large equipment in multiple fields, with excellent heavy-duty adaptability and operational reliability.
