61828M

61828M is a single-row deep groove ball bearing with a specially optimized design (corresponding to the M marking). Its core function is to provide a high rigidity and stability support component for medium to heavy load scenarios. It is specifically designed for industrial equipment that has advanced requirements for rotational accuracy, bearing strength, and adaptability to working conditions, offering reliable rotational support. It retains the compact structure of the 61828 series with an inner diameter of 140mm, an outer diameter of 175mm, and a width of 18mm. It uses GCr15 high-carbon chromium bearing steel as the main material and undergoes process optimization or structural improvements corresponding to the M marking to further enhance structural rigidity and wear resistance. It can stably withstand larger radial loads and bidirectional axial loads. This bearing has a low friction coefficient and precise size accuracy, is suitable for medium-high speed operation requirements, supports open or sealed customization, and is pre-filled with long-lasting lithium-based composite lubricating grease upon leaving the factory. It has low maintenance frequency and is widely used in large motor shaft systems, industrial gearboxes, precision machine auxiliary components, key parts of automated production lines, metallurgical equipment, heavy machinery transmission, and other fields, providing a long-lasting, stable, and low-maintenance rotational support solution for equipment under high-load and high-precision conditions.
