Toothless Three Row Cylindrical Roller Slewing Bearing

The toothless three-row cylindrical roller slew bearing is a high-load mechanical core component specially designed for heavy-load conditions. It consists of an inner ring, an outer ring and three rows of independently arranged cylindrical rollers. The ring-less structure allows it to focus on load-bearing and rotation functions, and is suitable for scenarios where bearings are not required to transmit power. Its core advantage lies in the division of labor design of three rows of rollers: two rows of rollers are arranged in the axial direction and are specially designed to bear bidirectional axial loads; one row of rollers are arranged in the radial direction and are responsible for carrying radial loads. The three rows of rollers work together to efficiently withstand huge axial force, radial force and overturning moment at the same time. The load-bearing capacity far exceeds that of single-row or double-row structures, and the rollers and raceways are in line contact, with even load…
