61822

61822, as a 618 series large-sized deep groove ball bearing, its core positioning is a compact installation-friendly and high-speed stable general-purpose supporting component for medium and heavy-duty scenarios. It is specifically designed for medium and high-speed operations where high requirements are placed on bearing capacity, operational precision, and structural compatibility. It uses GCr15 high-carbon chromium bearing steel as the main body and a stamped steel cage. With a 110mm inner diameter, 140mm outer diameter, and 16mm width, the compact size simplifies the installation space while enhancing the medium and heavy-duty bearing capacity. It can stably withstand radial loads and bidirectional axial loads. Its low friction characteristics ensure the efficiency of medium and high-speed operation. It offers open or sealed design options to suit different usage scenarios. The open model is convenient for lubrication replenishment, while the sealed model prevents contamination and leakage, reducing maintenance costs. Its rated dynamic and static loads can fully meet the requirements of medium and heavy-duty scenarios, and is widely used in large motor shaft systems, industrial gearboxes, heavy machinery transmission structures, precision instruments and equipment, engineering machinery配套， and automated production lines， providing precise， stable， and long-lasting rotational support for high-load and medium-high-speed operating equipment.
