61848M

61848M is a super-large-sized heavy-duty single-row deep groove ball bearing that has been strengthened through the M marking process. Its core function is to serve as a high-load, high-durability rotating support component for heavy industrial environments with ultra-high pressure and continuous operation. It is specifically designed to provide reliable protection for large and heavy equipment that has strict requirements for load capacity, structural stability, and fatigue resistance. It features a compact structure with an inner diameter of 240mm, an outer diameter of 290mm, and a width of 24mm. It is suitable for the limited installation space of heavy equipment and is made from GCr15 high-carbon chromium bearing steel (corresponding to 52100 bearing steel). The raceway and rolling elements are manufactured, and after special process strengthening, the wear resistance and fatigue strength are significantly improved. It can stably withstand radial loads and bidirectional axial loads under ultra-high pressure heavy-duty conditions. The low-friction design is suitable for medium-speed operation requirements and supports open or sealed customization. Factory-installed long-lasting lithium-based composite lubricating grease is provided, resulting in low maintenance costs. It is widely used in large heavy motor shaft systems, metallurgical ultra-heavy equipment, core transmission systems of mining machinery, heavy industrial gearboxes, port lifting equipment, heavy compressors and water pumps, general extreme heavy-load machinery, and heavy-load core parts of automated production lines, providing a durable and stable rotating support for ultra-high load and long-term continuous operation heavy conditions.
