61872M

The 61872M is a 618 series large-sized single-row deep groove ball bearing. Its core function is to be a highly stable and adaptable rotating component suitable for heavy industrial and heavy-load scenarios. It maintains the large-sized structure design of 360mm inner diameter, 440mm outer diameter, and 38mm width. While retaining the fatigue resistance and wear resistance of high-carbon chromium bearing steel, the M-type optimization design enhances the structural rigidity and operational smoothness. It has a strong bearing capacity of approximately 205kN for basic rated dynamic load and 320kN for basic rated static load, capable of stably withstanding large radial loads and certain bidirectional axial loads. Its low friction coefficient characteristic is suitable for long-term heavy-load working conditions and meets the requirements of long-term transmission. It is easy to install, has low maintenance costs, and can be quickly adapted to equipment without complex assembly processes. It is compatible with general lubrication schemes and various adjustment needs for different working conditions. It is widely used in heavy machine tool spindles, large motors and reducers, metallurgical heavy equipment, mining machinery, port lifting equipment, wind power core transmission systems, engineering hydraulic machinery, etc., providing reliable support for the core rotating parts of various large-sized heavy-load industrial equipment, and covering the stable transmission requirements of heavy machinery in multiple industries.
