23072

23072 is a double-row self-aligning roller bearing. Its core function is to provide high load capacity, self-alignment and reliable operation support for the shaft systems of heavy machinery. The inner diameter of this bearing is 360mm, the outer diameter is 540mm, and the width is 134mm. It adopts a double-row roller structure. The outer ring has one shared spherical raceway, and the inner ring has two raceways. This structure enables it to have automatic self-aligning performance, and it is less affected by the error caused by the angle between the shaft and the bearing housing seat or the bending of the shaft. It can withstand large radial loads and bidirectional axial loads. The basic rated dynamic load is between 2390kN and 2850kN, and the basic rated static load is between 4640kN and 4800kN. The limit speeds of different brands vary slightly. For example, the limit speed of NSK's 23072CAE4 grease-lubricated bearing is 530r/min, and the oil-lubricated limit speed is 670r/min. The limit speed of TIMKEN's 23072YMB grease-lubricated bearing is 680r/min, and the oil-lubricated limit speed is 800r/min. The 23072 bearing is suitable for industries such as metallurgy, mining, cement and building materials, as well as port machinery. It can be used in equipment like annealing furnaces, crushers, conveyors, mixers, etc. It can maintain stable performance in harsh working conditions and ensure the normal operation of the equipment.
