23030K

The 23030K is a tapered-hole self-aligning roller bearing. Its core function is to provide stable rotational support with high load capacity and strong adaptability for heavy equipment in the metallurgy, mining, and construction materials industries that have installation deviations or running vibrations. It is suitable for mechanical operation scenarios that require frequent handling of heavy loads and have requirements for installation flexibility. This bearing has a specification of 150mm inner diameter, 225mm outer diameter, and 56mm width. The suffix K corresponds to the tapered hole design, which enables convenient installation in conjunction with conical shaft necks and can adapt to different operating conditions by adjusting the tightness of the fit, significantly enhancing the convenience of installation and later disassembly and maintenance. It has a basic rated dynamic load of 445kN and a basic rated static load of 775kN. The grease lubrication limit speed reaches 1300r/min, and the oil lubrication can reach 2000r/min. Combined with the double-row rollers and spherical outer raceway structure of the self-aligning roller bearing, it can easily withstand large radial loads and bidirectional axial loads, and can automatically compensate for shaft deflection and installation deviations during equipment operation. It is made of GCR15 bearing steel, which ensures sufficient wear resistance and fatigue resistance in the long-term operation of heavy crushers, auxiliary equipment for rolling mills, cement mills, etc. Its balanced load-bearing capacity and flexible installation characteristics can reduce faults caused by improper assembly or fluctuations in operating conditions, providing a solid support foundation for the continuous and stable operation of various heavy machinery.
