61852M

61852M is a super-large-sized heavy-duty single-row deep groove ball bearing that has been deeply strengthened through the M marking process. Its core function is to serve as the key component for high-load, high-durability rotational support in extreme heavy industrial environments with ultra-high pressure and long-term continuous operation. It is specifically designed to provide reliable protection for large and heavy critical equipment that has strict requirements for load capacity, structural stability, and fatigue resistance life. It features an optimized compact structure with an inner diameter of 260mm, an outer diameter of 320mm, and a width of 26mm. It precisely fits the limited installation space of heavy equipment. The raceways and rolling elements are made of high-strength GCr15 high-carbon chromium bearing steel (corresponding to 52100 bearing steel). After special strengthening process treatment, its fatigue resistance strength, wear resistance and durability, and overall rigidity have been significantly improved. It can stably withstand radial loads and bidirectional axial loads under ultra-high pressure heavy-duty conditions. The low-friction design meets the requirements of medium-speed operation, and it supports open or sealed customization. Factory pre-installed with long-lasting lithium-based composite lubricating grease, it is convenient to maintain and has low costs. It is widely used in the core transmission systems of metallurgical ultra-heavy equipment, large heavy-duty motor shaft systems, key transmission components of mining machinery, heavy industrial gearboxes, port giant lifting equipment, high-pressure compressors and water pumps, general extreme heavy machinery, and heavy-load core parts of automated production lines, providing long-lasting and stable rotational support for ultra-high load and long-term continuous operation in extreme heavy-duty conditions.
