61880M/C4S0

The 61880M/C4S0 is a large-sized high-performance deep groove ball bearing of the 618 series. It is mainly targeted at industrial core transmission scenarios where there are strict requirements for bearing rigidity, stability, and adaptability under heavy load, high speed, and special working conditions. Based on the large-sized structure of 400mm inner diameter, 500mm outer diameter, and 46mm width, the M-type optimized design enhances the overall structural strength and operational smoothness of the bearing. The C4 large clearance specification is suitable for working conditions with significant temperature variations or installation deviations. The S0 special treatment process further improves the material's wear resistance and fatigue resistance. Combined with the excellent base material characteristics of high-carbon chromium bearing steel (GCr15), it has strong bearing capacity and can stably withstand large radial loads and certain bidirectional axial loads. The low friction coefficient design ensures the reliability of long-term continuous operation. This bearing is easy to install, has low maintenance costs, and can flexibly adapt to metallurgical heavy rolling equipment, high-precision heavy machine spindles, large motors and reducers, wind power core transmission systems, port lifting equipment, engineering hydraulic machinery and other fields. It is also compatible with complex working conditions such as high temperature and vibration, providing precise, stable and long-lasting rotational support for various large-sized heavy-load high-end industrial equipment. It also takes into account the heavy-load adaptability, working condition compatibility and high-precision transmission advantages, meeting the strict requirements of various industries for core rotating components.
