61820

61820, as a 618 series large-sized deep groove ball bearing, its core function is to serve as a universal high-speed supporting component suitable for medium-heavy loads and compact installation spaces. It is specifically designed for medium-high-speed operations where there are high requirements for structural strength, operational stability, and load-bearing capacity. It uses GCr15 high-carbon chromium bearing steel as the main body and a stamped steel cage. With a 100mm inner diameter, 125mm outer diameter, and 13mm width, the compact size not only simplifies the installation space but also enhances the medium-heavy load-bearing performance. It can stably withstand radial loads and bidirectional axial loads, featuring low friction and high rotational speed characteristics. It offers open or sealed design options to adapt to different working conditions. The open version is convenient for flexible lubrication replenishment, while the sealed version can effectively prevent contamination and leakage, reducing maintenance frequency. Its rated dynamic and static loads can fully meet the requirements of medium-heavy load 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 stable， long-lasting， and reliable rotational support for high-load and medium-high-speed operating equipment.
