double row cylindrical roller bearing
Double-row cylindrical roller bearing is a type of rolling bearing with two rows of cylindrical rollers, widely used in industrial equipment requiring high rigidity and load carrying capacity. The main structure includes an inner ring, an outer ring, two columns of cylindrical rollers and a cage. Due to the double-row design, the roller is in linear contact with the raceway, which can withstand greater radial loads while providing higher rigidity and stability. Double-row cylindrical roller bearings are suitable for high-precision and high-speed operation conditions, and are often used in machine tool spindles, rolling mills, heavy machinery and other fields. Although it mainly bears radial loads, it can also bear certain axial loads. Regular lubrication and maintenance can extend its service life and ensure reliable operation of the equipment.
