Three Row Cylindrical Roller Slewing Baring With External Toothed Ring

The three-row cylindrical roller slewing bearing with toothed outer ring is an integrated mechanical core component tailor-made for heavy-load working conditions. It consists of an inner ring, an outer ring with an outer ring gear and three rows of independent cylindrical rollers. It has both super load-bearing and direct power transmission functions.Its core advantage lies in the dual design of "loading + transmission": first, three rows of rollers are divided into load bearings**, two rows of axial rollers are specially designed to bear bidirectional axial loads, and one row of radial rollers bear radial loads. The line contact structure allows the load to be evenly distributed and can withstand huge shafts. The load capacity of axial force, radial force and overturning moment far exceeds that of single/double row bearings; secondly, the outer ring gear transmission**, the precision ring gear machined on the outer ring can directly mesh with the driving pinion, eliminating the need for intermediate transmission parts, achieving efficient power transmission and simplifying equipment layout.
This bearing is widely used in heavy-load equipment such as port gantry cranes, large mining excavators, wind power yaw and pitch systems, and metallurgical converters. When working, it not only ensures stable rotation under heavy load through three rows of rollers, but also uses the outer ring gear to complete the power connection, effectively meeting the safe and efficient operation requirements of heavy machinery under harsh working conditions, and is a key supporting component of the heavy-load system.Centripetal Bearings,High-Quality Bearings,Industrial Bearings,Explore our premium centripetal and radial ball bearings.
