61840M

61840M is a large-sized heavy-duty single-row deep groove ball bearing that has been strengthened by the M marking process. Its core function is to serve as a high-capacity and highly durable rotating support component for continuous operation scenarios in heavy industry. It is specifically designed to provide reliable protection for large equipment with strict requirements for bearing strength, structural stability, and fatigue resistance. It features a compact structure with an inner diameter of 200mm, an outer diameter of 250mm, and a width of 24mm. It is suitable for the limited installation space of heavy equipment and is made of GCr15 high-carbon chromium bearing steel, which has been specially optimized through process improvements. This design enhances the wear resistance and durability, as well as the overall rigidity. It can stably withstand radial loads and bidirectional axial loads under heavy-duty conditions. The low-friction design is suitable for medium-high-speed operation requirements and supports open or sealed customization. It is factory-pre-installed with long-lasting lithium-based composite lubricating grease, resulting in low maintenance costs. It is widely used in large heavy motor shaft systems, heavy industrial gearboxes, metallurgical heavy equipment, mining mechanical transmission systems, and the core parts of automated production lines with heavy loads, providing a durable and stable rotating support for high-load and continuous operation heavy-duty conditions.
